We have decelerated 3 00:00:09,600 --> 00:00:11,320 Speaker 1: and see clearance to titanium. 4 00:00:11,520 --> 00:00:15,200 Speaker 2: Greetings, USS Hamlet's Father's Ghost. This is Mustard Seed. Can 5 00:00:15,240 --> 00:00:16,520 Speaker 2: you state the purpose of your visit? 6 00:00:16,920 --> 00:00:18,079 Speaker 3: Roger that Mustard Seed. 7 00:00:18,120 --> 00:00:20,760 Speaker 1: I have two hundred and fifty Shakespeare enthusiast on board, 8 00:00:20,880 --> 00:00:23,360 Speaker 1: just waking up for a tour of the Uranian moons. 9 00:00:23,880 --> 00:00:26,920 Speaker 1: Our visit to the Royal Automated Uranian Theater on Titanius 10 00:00:26,960 --> 00:00:28,360 Speaker 1: should be registered in the lock. 11 00:00:29,040 --> 00:00:33,800 Speaker 2: All right, Roger that USSHFG. I can confirm your reservation 12 00:00:34,000 --> 00:00:38,160 Speaker 2: now and docking credentials are good to go with your passengers. 13 00:00:38,200 --> 00:00:41,320 Speaker 2: A pleasant and safe visit to the Uranian satellite system. 14 00:00:41,440 --> 00:00:46,360 Speaker 2: The next automated Thespianoid performance will be let's see Ooh 15 00:00:46,800 --> 00:00:49,280 Speaker 2: Edward the third Well, better luck next time. 16 00:00:53,640 --> 00:00:57,800 Speaker 4: Welcome to Stuff to Blow Your Mind, the production of iHeartRadio. 17 00:01:03,560 --> 00:01:05,479 Speaker 3: Hey you, welcome to Stuff to Blow your Mind. 18 00:01:05,600 --> 00:01:08,560 Speaker 2: My name is Robert Lamb and I'm Joe McCormick, and 19 00:01:08,600 --> 00:01:11,280 Speaker 2: we're back with Part two of our series on the 20 00:01:11,319 --> 00:01:15,520 Speaker 2: planet Uranus and its moons. Now in Part one, we 21 00:01:15,640 --> 00:01:19,880 Speaker 2: focused mainly on the planet itself. This time we're going 22 00:01:19,920 --> 00:01:22,880 Speaker 2: to start getting more into the moons. Maybe we'll do 23 00:01:23,000 --> 00:01:25,399 Speaker 2: all of the moons this time. I think last time 24 00:01:25,400 --> 00:01:27,600 Speaker 2: we promised it would happen. We'll see whether we can 25 00:01:27,600 --> 00:01:30,240 Speaker 2: fit it all into one episode. But I had a 26 00:01:30,280 --> 00:01:33,200 Speaker 2: few more core planet digressions burning a hole in my 27 00:01:33,240 --> 00:01:36,039 Speaker 2: pocket that I wanted to mention before we fly off 28 00:01:36,080 --> 00:01:38,679 Speaker 2: to the satellites. Are you okay with that? Rob, Let's 29 00:01:38,680 --> 00:01:38,960 Speaker 2: do it. 30 00:01:39,400 --> 00:01:39,480 Speaker 3: So. 31 00:01:39,680 --> 00:01:42,800 Speaker 2: First of all, I was wondering what's the density of Uranus, 32 00:01:43,280 --> 00:01:46,880 Speaker 2: And it turns out that Uranus is the second least 33 00:01:47,200 --> 00:01:50,360 Speaker 2: dense planet in the Solar System at one point twenty 34 00:01:50,360 --> 00:01:54,160 Speaker 2: seven grams per cubic centimeter. The only planet less dense 35 00:01:54,240 --> 00:01:57,600 Speaker 2: is actually Saturn, the second largest planet in the Solar System. 36 00:01:58,160 --> 00:02:01,320 Speaker 2: You might wonder which planet is the dense baby, that's Earth. 37 00:02:01,640 --> 00:02:02,160 Speaker 3: That's Earth. 38 00:02:02,440 --> 00:02:04,520 Speaker 2: We are at five point five to one grams per 39 00:02:04,520 --> 00:02:08,120 Speaker 2: cubic centimeter, so we are the density king. But one 40 00:02:08,200 --> 00:02:10,760 Speaker 2: of the real things I wanted to return to was 41 00:02:10,760 --> 00:02:14,360 Speaker 2: a question of materials, because in the last episode we 42 00:02:15,080 --> 00:02:18,440 Speaker 2: mentioned just giving sort of an overview of the basics 43 00:02:18,440 --> 00:02:22,160 Speaker 2: of the planet, that most of the mass of Uranus 44 00:02:22,400 --> 00:02:27,320 Speaker 2: is thought to be a hot, dense fluid of ices, 45 00:02:27,800 --> 00:02:31,600 Speaker 2: probably surrounding a rocky core of some sort. And though 46 00:02:32,080 --> 00:02:34,600 Speaker 2: it might be kind of strange to hear like hot 47 00:02:35,080 --> 00:02:38,639 Speaker 2: dense fluid of ices, that almost kind of doesn't make 48 00:02:38,680 --> 00:02:41,520 Speaker 2: sense based on our definition of ice. And it's true 49 00:02:41,560 --> 00:02:43,120 Speaker 2: that a lot of this ice is going to be 50 00:02:43,240 --> 00:02:46,280 Speaker 2: different than the kind of ice we know. So I 51 00:02:46,320 --> 00:02:48,560 Speaker 2: was reading more about this in an article by a 52 00:02:48,639 --> 00:02:53,120 Speaker 2: planetary atmospheric scientist named Amy Simon, who is a senior 53 00:02:53,160 --> 00:02:56,520 Speaker 2: researcher at NASA Goddard, and this was written for the 54 00:02:56,560 --> 00:02:59,680 Speaker 2: magazine of the Planetary Society. The article is called the 55 00:03:00,400 --> 00:03:03,560 Speaker 2: of the Ice Giants, and one of the questions Simon 56 00:03:03,560 --> 00:03:07,960 Speaker 2: addresses in this article is why are the planets Uranus 57 00:03:08,040 --> 00:03:12,920 Speaker 2: and Neptune called ice giants as opposed to regular gas giants. 58 00:03:13,280 --> 00:03:17,200 Speaker 2: It's because, compared to regular gas giants like Jupiter and Saturn, 59 00:03:17,320 --> 00:03:20,880 Speaker 2: Uranus and Neptune are composed of a higher proportion of 60 00:03:21,040 --> 00:03:25,840 Speaker 2: ice forming molecules like water and methane, though much of 61 00:03:25,880 --> 00:03:29,799 Speaker 2: that so called ice is in a phase unfamiliar to 62 00:03:29,880 --> 00:03:33,000 Speaker 2: us on the surface of Earth. Cymon writes quote, ice 63 00:03:33,080 --> 00:03:36,520 Speaker 2: giants are mostly water, probably in the form of a 64 00:03:36,640 --> 00:03:41,880 Speaker 2: supercritical fluid. The visible clouds likely consist of ice crystals 65 00:03:41,920 --> 00:03:47,720 Speaker 2: with different compositions, So regarding supercritical fluid, a supercritical fluid 66 00:03:47,800 --> 00:03:51,840 Speaker 2: doesn't behave exactly like a liquid, gas or a solid. 67 00:03:51,960 --> 00:03:56,360 Speaker 2: It's an emergent state of matter occurring at temperatures and 68 00:03:56,440 --> 00:04:00,240 Speaker 2: pressures beyond what is known as the critical point for 69 00:04:00,280 --> 00:04:04,840 Speaker 2: each substance. And Simon has a very good paragraph clarifying 70 00:04:04,920 --> 00:04:08,280 Speaker 2: the planetary science use of the term ice, which could 71 00:04:08,320 --> 00:04:11,280 Speaker 2: help clear up any confusion there. She says that on 72 00:04:11,360 --> 00:04:13,880 Speaker 2: Earth we usually use the term ice to refer to 73 00:04:14,000 --> 00:04:16,760 Speaker 2: just water H two O when it is frozen solid, 74 00:04:17,160 --> 00:04:20,360 Speaker 2: but planetary astronomers use the word ice to refer to 75 00:04:20,600 --> 00:04:25,520 Speaker 2: any condensable molecule in its solid form. She writes, quote, 76 00:04:25,760 --> 00:04:30,760 Speaker 2: these tend to be highly reflective form clouds, and unlike minerals, 77 00:04:31,160 --> 00:04:35,360 Speaker 2: can readily change between liquid, solid and gas states at 78 00:04:35,400 --> 00:04:40,160 Speaker 2: relatively low temperatures. So we're mainly familiar with water ice 79 00:04:40,240 --> 00:04:43,160 Speaker 2: on the surface of Earth, but throughout space there are 80 00:04:43,279 --> 00:04:48,240 Speaker 2: lots of ices. There's methane, ammonia, hydrogen sulfide, and phosphene 81 00:04:48,240 --> 00:04:52,839 Speaker 2: pH three, and these are all condensable molecules and could 82 00:04:52,920 --> 00:04:56,839 Speaker 2: all freeze in the atmosphere of Uranus and Neptune also 83 00:04:56,920 --> 00:04:59,680 Speaker 2: for that matter, and Simon writes that most of the 84 00:04:59,680 --> 00:05:02,360 Speaker 2: cloud clouds we see in the atmospheres of these ice 85 00:05:02,440 --> 00:05:07,400 Speaker 2: giants are clouds of methane ice crystals or hydrogen sulfide ice, 86 00:05:07,640 --> 00:05:12,280 Speaker 2: So there's probably weird supercritical fluids down below, and then 87 00:05:12,279 --> 00:05:16,080 Speaker 2: an atmosphere above. The atmosphere in its gas contents, is 88 00:05:16,160 --> 00:05:20,280 Speaker 2: mostly hydrogen and helium, but that atmosphere is probably full 89 00:05:20,360 --> 00:05:23,360 Speaker 2: of traces of different kinds of ice, including not just 90 00:05:23,960 --> 00:05:27,320 Speaker 2: H two O, but things like ammonia and methane. And 91 00:05:27,560 --> 00:05:31,600 Speaker 2: speaking of methane, as we mentioned last time, the blue 92 00:05:31,720 --> 00:05:35,720 Speaker 2: color of both Neptune and Uranus appears to come from 93 00:05:35,839 --> 00:05:39,720 Speaker 2: the presence of methane in their atmospheres, which absorbs the 94 00:05:39,760 --> 00:05:43,600 Speaker 2: red wavelengths of light from the sun and reflects only 95 00:05:43,640 --> 00:05:47,800 Speaker 2: the blue spectrum. But the question is why is Urinus 96 00:05:47,880 --> 00:05:50,680 Speaker 2: a paler shade of blue than Neptune. If you look 97 00:05:50,720 --> 00:05:53,359 Speaker 2: at Neptune, it's often kind of a royal blue, whereas 98 00:05:53,400 --> 00:05:58,200 Speaker 2: in true color, Uranus appears kind of a gray green blue. 99 00:05:58,680 --> 00:06:01,920 Speaker 2: Simon writes that this is quote either because Urinus has 100 00:06:02,040 --> 00:06:05,560 Speaker 2: more haze, so more kind of a cloudy outer shell, 101 00:06:06,720 --> 00:06:09,679 Speaker 2: but she goes on or because Neptune's atmosphere has another 102 00:06:10,080 --> 00:06:15,600 Speaker 2: unidentified constituent that absorbs longer wavelength light even more strongly, 103 00:06:15,720 --> 00:06:18,600 Speaker 2: and of course longer wavelength light would be more red 104 00:06:18,600 --> 00:06:21,800 Speaker 2: shifted toward the red end of the visible spectrum. Okay, 105 00:06:21,800 --> 00:06:24,919 Speaker 2: so that's ice, the atmosphere, the makeup of the planet. 106 00:06:24,920 --> 00:06:27,240 Speaker 2: But there's one more thing you may have seen headlines 107 00:06:27,279 --> 00:06:30,920 Speaker 2: about regarding Urinus in Neptune that if you have seen 108 00:06:30,920 --> 00:06:33,520 Speaker 2: these headlines, I'm sure you're wondering about it, and that 109 00:06:33,680 --> 00:06:37,040 Speaker 2: is the claim that some experts have argued that it 110 00:06:37,240 --> 00:06:42,680 Speaker 2: likely rains diamonds on Urinus in Neptune. And from what 111 00:06:42,760 --> 00:06:45,880 Speaker 2: I can tell, this is true. Now, this is obviously 112 00:06:45,880 --> 00:06:49,840 Speaker 2: something we haven't been able to detect directly with probes 113 00:06:49,920 --> 00:06:54,120 Speaker 2: or anything, so nobody can sense this happening. Instead, it's 114 00:06:54,160 --> 00:06:56,960 Speaker 2: based on what we do know about the planets and 115 00:06:57,240 --> 00:07:01,039 Speaker 2: argue and sort of extrapolating logically from the starting facts. 116 00:07:01,320 --> 00:07:03,880 Speaker 2: So how does the logic go? Well, I was reading 117 00:07:03,920 --> 00:07:07,039 Speaker 2: about this in an article for space dot Com by 118 00:07:07,080 --> 00:07:12,000 Speaker 2: the Sunny Stonybrook astrophysicist Paul M. Sutter, and in this article, 119 00:07:12,080 --> 00:07:16,440 Speaker 2: Sutter explains that we know from mathematical models that the 120 00:07:16,480 --> 00:07:21,160 Speaker 2: inner mantles of ice giants probably have temperatures of about 121 00:07:21,240 --> 00:07:25,480 Speaker 2: seven thousand kelvins or over sixty seven hundred celsius and 122 00:07:25,680 --> 00:07:29,720 Speaker 2: pressure about six million times the atmospheric pressure on the 123 00:07:29,760 --> 00:07:33,600 Speaker 2: surface of Earth. Meanwhile, higher up in the mantle, things 124 00:07:33,600 --> 00:07:37,600 Speaker 2: are cooler about two thousand kelvins and only two hundred 125 00:07:37,640 --> 00:07:42,560 Speaker 2: thousand times Earth's atmospheric pressure. And we know that water, ammonia, 126 00:07:42,640 --> 00:07:46,120 Speaker 2: and methane are present within that mantle. So what happens 127 00:07:46,120 --> 00:07:50,920 Speaker 2: to those substances in those conditions, Well, these conditions of 128 00:07:50,960 --> 00:07:55,800 Speaker 2: temperature and pressure would tend to tear apart molecules of methane, 129 00:07:55,920 --> 00:08:00,520 Speaker 2: methane is H four carbon, and hydrogen. And when those 130 00:08:00,640 --> 00:08:04,200 Speaker 2: molecules get torn apart, we are left with free carbon. 131 00:08:04,360 --> 00:08:08,320 Speaker 2: Free carbon tends to link together with other free carbon 132 00:08:08,600 --> 00:08:12,400 Speaker 2: to form long chains of carbon. What happens to long 133 00:08:12,480 --> 00:08:16,320 Speaker 2: chains of pure carbon under high pressure that gets pressed 134 00:08:16,400 --> 00:08:20,320 Speaker 2: into a diamond? These diamonds would tend to then drop 135 00:08:20,400 --> 00:08:24,760 Speaker 2: down to lower in the mantle where high temperatures vaporize them, 136 00:08:24,880 --> 00:08:27,679 Speaker 2: and then they float back up into the upper mantle, 137 00:08:27,760 --> 00:08:31,440 Speaker 2: and then the cycle repeats, so you're left with diamond rain. 138 00:08:32,120 --> 00:08:35,360 Speaker 2: Sounds like the name of a great alternate universe collaborative 139 00:08:35,400 --> 00:08:38,640 Speaker 2: sci fi movie musical between Prince and David Bowie. Wish 140 00:08:38,640 --> 00:08:40,920 Speaker 2: I could have seen it, but it does appear to 141 00:08:40,920 --> 00:08:44,600 Speaker 2: be very likely a physical reality on Uranus and Neptune 142 00:08:44,640 --> 00:08:45,040 Speaker 2: as well. 143 00:08:45,800 --> 00:08:48,800 Speaker 1: So you're saying that all we have to do is 144 00:08:49,360 --> 00:08:53,640 Speaker 1: jet out to Urinus, dip down into the atmosphere of Uranus, 145 00:08:53,880 --> 00:08:57,200 Speaker 1: scoop up some diamonds, then get back to Earth and 146 00:08:57,240 --> 00:08:58,199 Speaker 1: we're set for life. 147 00:08:58,520 --> 00:09:00,640 Speaker 2: I've always said when I look at but the stars 148 00:09:00,679 --> 00:09:05,800 Speaker 2: at night, what I see is profit. Okay, but one 149 00:09:05,800 --> 00:09:09,400 Speaker 2: more digression before we get to the moons. Since part one, 150 00:09:09,480 --> 00:09:12,120 Speaker 2: we actually got a really great bit of listener mail 151 00:09:12,360 --> 00:09:15,240 Speaker 2: from Joe, not me, but a different Joe who listens 152 00:09:15,280 --> 00:09:18,800 Speaker 2: to the show, who brought to our attention some really 153 00:09:18,840 --> 00:09:22,400 Speaker 2: awesome photos of Uranus recently captured by the James Web 154 00:09:22,440 --> 00:09:26,679 Speaker 2: Space Telescope. Joe writes, quote, I've long awaited with tremulous 155 00:09:26,679 --> 00:09:30,839 Speaker 2: anticipation the resumption of your ural journey to the Heliopause 156 00:09:31,200 --> 00:09:34,240 Speaker 2: and was thrilled to see the recumbent sky King Uranus 157 00:09:34,240 --> 00:09:37,920 Speaker 2: on my podcast Feed Your Choice was timely indeed, as 158 00:09:37,960 --> 00:09:41,200 Speaker 2: the James Web Space Telescope just last month released some 159 00:09:41,360 --> 00:09:46,120 Speaker 2: spectacular visuals of Uranus. These images bost greater clarity than 160 00:09:46,120 --> 00:09:49,640 Speaker 2: the Hubbles effort, especially of the planet's rings. I love 161 00:09:49,720 --> 00:09:51,840 Speaker 2: living under a sky that will never run out of 162 00:09:51,840 --> 00:09:54,640 Speaker 2: extraordinary things to look at and talk about, and I 163 00:09:54,679 --> 00:09:59,160 Speaker 2: appreciate when you cast your gaze upward from time to time. Joe, Well, 164 00:09:59,160 --> 00:10:01,360 Speaker 2: thank you, Joe. Because I had not seen these, I 165 00:10:01,400 --> 00:10:04,960 Speaker 2: looked them up and this is fantastic. So I saw 166 00:10:05,000 --> 00:10:08,720 Speaker 2: these within the context of a NASA press release from 167 00:10:08,800 --> 00:10:12,520 Speaker 2: April sixth, twenty twenty three that Joe shared with us Rob, 168 00:10:12,520 --> 00:10:15,480 Speaker 2: I pasted these two photos here in the outline. One 169 00:10:15,559 --> 00:10:18,120 Speaker 2: is just zoomed in on the planet from the more 170 00:10:18,200 --> 00:10:21,560 Speaker 2: zoomed out second one. I would say, from my perspective, 171 00:10:21,960 --> 00:10:26,160 Speaker 2: these images are gorgeous. They fill one with awe at 172 00:10:26,200 --> 00:10:29,319 Speaker 2: the picture of this frosty, dark recess where the Blue 173 00:10:29,360 --> 00:10:32,800 Speaker 2: God lives. And this might sound a little bit weird, 174 00:10:33,040 --> 00:10:35,760 Speaker 2: but I actually mean this in the best possible way. Somehow, 175 00:10:35,800 --> 00:10:40,719 Speaker 2: in these images, Urinus looks more like an optical artifact 176 00:10:41,000 --> 00:10:44,640 Speaker 2: than a physical object, as if the planet were like 177 00:10:44,760 --> 00:10:48,920 Speaker 2: a glint or a lens flare. And to explain what 178 00:10:48,960 --> 00:10:51,600 Speaker 2: I mean, so the planet is pictured on its side, 179 00:10:51,640 --> 00:10:54,559 Speaker 2: because of course that's how it is. We're not seeing 180 00:10:54,559 --> 00:10:58,160 Speaker 2: the rings laterally from the side, crossing over and behind 181 00:10:58,240 --> 00:11:01,439 Speaker 2: the planet, like we do in most photos of Saturn. Instead, 182 00:11:01,440 --> 00:11:04,720 Speaker 2: we're seeing the rings encircling the planet in an egg 183 00:11:04,760 --> 00:11:08,600 Speaker 2: shape because we're looking roughly down toward the north pole, 184 00:11:09,440 --> 00:11:13,920 Speaker 2: which faces sideways. And in this particular photo, though this 185 00:11:14,040 --> 00:11:17,640 Speaker 2: is not exactly true color, the planet is pale blue 186 00:11:17,640 --> 00:11:21,000 Speaker 2: with a white cap, and the rings sort of fade 187 00:11:21,200 --> 00:11:26,000 Speaker 2: outward to inward from a screaming fluorescent white to a 188 00:11:26,200 --> 00:11:29,960 Speaker 2: dim blue gray as they sink toward the planet's atmosphere. 189 00:11:30,600 --> 00:11:33,760 Speaker 2: And the sunlight seems blinding in these images because we 190 00:11:33,840 --> 00:11:36,520 Speaker 2: actually see it gleaming off the edge of the planet, 191 00:11:36,559 --> 00:11:39,600 Speaker 2: which is even weirder because, as I said, the disk 192 00:11:39,679 --> 00:11:42,480 Speaker 2: of Urinus facing us looks like a glint or a 193 00:11:42,520 --> 00:11:45,559 Speaker 2: gleam itself. And in the more zoomed out of these 194 00:11:45,600 --> 00:11:48,120 Speaker 2: two photos, we can see the blue dots of the 195 00:11:48,200 --> 00:11:52,000 Speaker 2: larger moons surrounding it, also sending out these sort of 196 00:11:52,080 --> 00:11:56,000 Speaker 2: shafts of reflected light in these hexagonal criss crosses out 197 00:11:56,040 --> 00:11:56,600 Speaker 2: into space. 198 00:11:57,120 --> 00:11:59,880 Speaker 1: Yeah, these images are gorgeous. It makes it look like 199 00:12:00,160 --> 00:12:06,560 Speaker 1: Urinus is a planet designed by Japanese illustrator Hajimi Soriyama, whose, 200 00:12:06,600 --> 00:12:09,200 Speaker 1: of course I think he worked on the design for 201 00:12:09,240 --> 00:12:15,760 Speaker 1: the original Sony Aibo robot, but also mostly known for 202 00:12:17,200 --> 00:12:21,640 Speaker 1: robot pin up like really shiny, silvery robot pin up models. 203 00:12:22,800 --> 00:12:25,280 Speaker 1: This artist is on my mind because the movie we're 204 00:12:25,320 --> 00:12:29,160 Speaker 1: watching Friday in for Weird House Cinema, this artist is 205 00:12:29,240 --> 00:12:32,200 Speaker 1: credited like deep down in the credits because there's a 206 00:12:32,280 --> 00:12:34,160 Speaker 1: character in the movie that has some of this art 207 00:12:34,280 --> 00:12:38,760 Speaker 1: up on his workstation. But this kind of but there's 208 00:12:38,800 --> 00:12:43,560 Speaker 1: a certain aside from like the female robot bodies in 209 00:12:43,559 --> 00:12:46,440 Speaker 1: his art, there is this kind of like glimmering, like 210 00:12:46,559 --> 00:12:50,400 Speaker 1: silvery perfection to things. And that's what that's what I 211 00:12:50,480 --> 00:12:53,240 Speaker 1: kind of get from this image of Urinus. And if 212 00:12:53,280 --> 00:12:55,400 Speaker 1: you're into planets, like I mean, put it on a calendar. 213 00:12:55,480 --> 00:12:56,600 Speaker 1: It looks it looks nice. 214 00:12:56,840 --> 00:12:58,920 Speaker 2: It is beautiful. And I will say the blue in 215 00:12:58,960 --> 00:13:01,960 Speaker 2: this photo, as I alluded to, is not exactly true 216 00:13:01,960 --> 00:13:05,400 Speaker 2: color from the visible spectrum. I think it's approximate. So 217 00:13:05,760 --> 00:13:09,360 Speaker 2: the image is from the webs near infrared camera combining 218 00:13:09,440 --> 00:13:13,000 Speaker 2: data from two filters. According to the press release, it 219 00:13:13,080 --> 00:13:16,400 Speaker 2: was one point four and three point zero microns, and 220 00:13:16,440 --> 00:13:19,079 Speaker 2: then the article explains these are coded out to blue 221 00:13:19,120 --> 00:13:23,960 Speaker 2: and orange respectively. Now I mentioned the white cap that 222 00:13:24,000 --> 00:13:28,040 Speaker 2: we see on Uranus in this photo. The article explains 223 00:13:28,080 --> 00:13:30,520 Speaker 2: that this is known as the polar cap, and it 224 00:13:30,559 --> 00:13:34,160 Speaker 2: seems to manifest when the pole of the planet goes 225 00:13:34,240 --> 00:13:38,000 Speaker 2: into direct sunlight during its long polar summer, which, again, 226 00:13:38,640 --> 00:13:41,200 Speaker 2: as we talked about last time, lasts many earth years 227 00:13:41,240 --> 00:13:43,920 Speaker 2: at a time, and then the cap seems to disappear 228 00:13:44,040 --> 00:13:46,480 Speaker 2: in the fall when it starts to turn away from 229 00:13:46,480 --> 00:13:49,040 Speaker 2: the sun. As far as I could find, we aren't 230 00:13:49,080 --> 00:13:51,960 Speaker 2: sure exactly what causes this, or maybe if somebody knows, 231 00:13:51,960 --> 00:13:54,640 Speaker 2: I just didn't dig that up. But so regarding the 232 00:13:54,720 --> 00:13:59,840 Speaker 2: beautiful rings in the picture, Urinus has thirteen known rings, 233 00:14:00,040 --> 00:14:02,440 Speaker 2: and you can see eleven of them in this photo, 234 00:14:02,520 --> 00:14:05,560 Speaker 2: though some of them are so bright that they bleed 235 00:14:05,559 --> 00:14:08,800 Speaker 2: together in the image. There are nine major rings and 236 00:14:08,840 --> 00:14:11,280 Speaker 2: then there are two kind of faint dusty rings that 237 00:14:11,320 --> 00:14:14,240 Speaker 2: were discovered during the approach of Voyager two in nineteen 238 00:14:14,280 --> 00:14:18,400 Speaker 2: eighty six. But speaking of those, rings and moons. Rings 239 00:14:18,400 --> 00:14:22,160 Speaker 2: and moons sometimes have an interesting origin story, so I 240 00:14:22,200 --> 00:14:26,040 Speaker 2: was wondering where do experts generally think they came from 241 00:14:26,280 --> 00:14:29,120 Speaker 2: in the case of Uranus. Going back to that Planetary 242 00:14:29,160 --> 00:14:32,920 Speaker 2: Society article by Amy Simon, Simon writes that the medium 243 00:14:32,960 --> 00:14:37,320 Speaker 2: sized moons of Uranus probably formed in place at the 244 00:14:37,360 --> 00:14:41,920 Speaker 2: same time or after whatever event it was that left 245 00:14:42,040 --> 00:14:44,560 Speaker 2: Uranus tilted on its side. And as we talked about 246 00:14:44,600 --> 00:14:48,200 Speaker 2: last time, it seems likely that Uranus was probably knocked 247 00:14:48,240 --> 00:14:50,680 Speaker 2: on its side and left colder than all the other 248 00:14:50,720 --> 00:14:54,920 Speaker 2: planets because of an impact with a large object, maybe 249 00:14:54,920 --> 00:14:58,720 Speaker 2: like an Earth sized planet billions of years ago. And 250 00:14:58,800 --> 00:15:02,120 Speaker 2: so what we're left with is that the moons orbit 251 00:15:02,320 --> 00:15:06,160 Speaker 2: Urinus on its equatorial plane, so like the planet itself 252 00:15:06,280 --> 00:15:09,960 Speaker 2: and like its rings, the moons are tilted at a 253 00:15:10,080 --> 00:15:13,200 Speaker 2: roughly ninety degree angle to the rest of the Solar System. 254 00:15:13,720 --> 00:15:16,200 Speaker 2: In general, the moons of Urinus are made of ice 255 00:15:16,320 --> 00:15:20,000 Speaker 2: and rock, usually slightly more ice than rock, and they 256 00:15:20,040 --> 00:15:24,240 Speaker 2: show some interesting surface features, like patterns of darkening on 257 00:15:24,320 --> 00:15:29,040 Speaker 2: their surfaces that are caused by some unknown material. Spectral 258 00:15:29,040 --> 00:15:33,000 Speaker 2: analysis reveals the presence of frozen carbon dioxide on a 259 00:15:33,000 --> 00:15:36,960 Speaker 2: lot of the moons. Meanwhile, the origin of the rings, 260 00:15:37,040 --> 00:15:41,640 Speaker 2: the consensus seems to be that they are created by 261 00:15:41,680 --> 00:15:46,840 Speaker 2: the shattering into dust and fragments of formerly solid moons. 262 00:15:47,120 --> 00:15:49,880 Speaker 2: And as we've seen with other planets, the sudden or 263 00:15:50,000 --> 00:15:53,240 Speaker 2: gradual smash up of moons can happen a number of ways, 264 00:15:53,960 --> 00:15:58,480 Speaker 2: by lots of little collisions with meteoroids or other objects, 265 00:15:58,600 --> 00:16:01,760 Speaker 2: or by tidal breakup due to gravity, in any case, 266 00:16:01,840 --> 00:16:07,600 Speaker 2: turning former larger satellites into smaller satellites and rings of 267 00:16:07,720 --> 00:16:08,640 Speaker 2: little fragments. 268 00:16:08,960 --> 00:16:12,720 Speaker 1: Yeah, it's fascinating. How from our human perspective we look 269 00:16:12,800 --> 00:16:15,200 Speaker 1: up at our moon, we consider the moons of other worlds, 270 00:16:15,240 --> 00:16:17,680 Speaker 1: and there's a certain certain stability to them, you know. 271 00:16:18,680 --> 00:16:20,840 Speaker 3: But if you look at. 272 00:16:20,600 --> 00:16:27,120 Speaker 1: Any planets, moons or moon, generally, you're looking at a 273 00:16:27,120 --> 00:16:32,600 Speaker 1: more violent relationship over the vast history of a given planet. 274 00:16:33,080 --> 00:16:45,320 Speaker 1: There's nothing peaceful about it. All right, Well, let's begin, 275 00:16:45,600 --> 00:16:49,280 Speaker 1: at least begin to dip into the moons of Uranus. 276 00:16:50,080 --> 00:16:51,920 Speaker 1: Like I said, we originally set out to do them all. 277 00:16:51,960 --> 00:16:54,280 Speaker 1: Maybe we won't do them all. Maybe we'll get part 278 00:16:54,360 --> 00:16:57,400 Speaker 1: way through the journey and we'll come back on Tuesday. 279 00:16:58,120 --> 00:17:00,880 Speaker 1: Who knows, Maybe we'll just we'll just get we'll finish 280 00:17:00,960 --> 00:17:02,800 Speaker 1: them up, and then we'll go right into Neptune. 281 00:17:03,800 --> 00:17:05,920 Speaker 3: There are no rules. We can do what we want. 282 00:17:06,720 --> 00:17:09,440 Speaker 1: So let's start with the inner moons of Uranus thirteen 283 00:17:09,520 --> 00:17:12,280 Speaker 1: total known. All right, We're going to start with a 284 00:17:12,320 --> 00:17:17,600 Speaker 1: pair of moons, Cordelia and Ophelia. These are named for 285 00:17:17,800 --> 00:17:20,760 Speaker 1: the youngest daughter of King Lear and of course Hamlet's 286 00:17:20,880 --> 00:17:26,919 Speaker 1: tragic beloved, respectively. The main significance of these moons is 287 00:17:26,960 --> 00:17:30,600 Speaker 1: that both Cordelia and Ophelia are shepherd moons, as their 288 00:17:30,600 --> 00:17:34,360 Speaker 1: gravity keeps Uranus's epsilon ring from dispersing. 289 00:17:34,600 --> 00:17:37,080 Speaker 2: Now, I thought this was interesting, so I was looking 290 00:17:37,160 --> 00:17:41,159 Speaker 2: up how exactly it is that shepherd moons work. What 291 00:17:41,160 --> 00:17:45,200 Speaker 2: does the shepherd moon do? These little small moons, how 292 00:17:45,240 --> 00:17:49,080 Speaker 2: do they keep a ring? Essentially, they keep a ring 293 00:17:49,240 --> 00:17:52,880 Speaker 2: in tight formation around the planet and clear these gaps 294 00:17:52,920 --> 00:17:56,440 Speaker 2: between the rings. And it seems that essentially it works 295 00:17:56,520 --> 00:17:59,480 Speaker 2: like this. So you've got a small moon and it's 296 00:17:59,600 --> 00:18:03,000 Speaker 2: orbiting planet. And imagine at first it's orbiting the planet 297 00:18:03,160 --> 00:18:07,639 Speaker 2: along with a bunch of other small particles sort of 298 00:18:07,680 --> 00:18:12,120 Speaker 2: within the lane of that small moon's orbit. Particles that 299 00:18:12,280 --> 00:18:16,720 Speaker 2: are ahead of the small moon will be attracted by 300 00:18:16,840 --> 00:18:20,560 Speaker 2: gravity to it, meaning if they're orbiting ahead of it, 301 00:18:20,600 --> 00:18:23,600 Speaker 2: they will naturally want to slow down in their orbit, 302 00:18:23,680 --> 00:18:27,920 Speaker 2: right because they're getting pulled toward this moon. But slowing 303 00:18:27,960 --> 00:18:31,199 Speaker 2: down in their orbit actually causes them to lose energy 304 00:18:31,640 --> 00:18:35,000 Speaker 2: and fall down closer to the planet that they're orbiting. 305 00:18:35,080 --> 00:18:37,359 Speaker 2: So these like dust and particles and things in the 306 00:18:37,440 --> 00:18:43,680 Speaker 2: ring actually end up sorting down into lower orbit rings. 307 00:18:44,200 --> 00:18:47,880 Speaker 2: And then meanwhile, things that are orbiting along the same 308 00:18:48,000 --> 00:18:51,080 Speaker 2: lane as this moon, that are behind it in its 309 00:18:51,200 --> 00:18:55,000 Speaker 2: orbit are attracted to it and thus sped up. And 310 00:18:55,040 --> 00:18:58,280 Speaker 2: as they get sped up trying to chase after this 311 00:18:58,680 --> 00:19:02,040 Speaker 2: moon by the force of gravity, that acceleration actually causes 312 00:19:02,119 --> 00:19:05,160 Speaker 2: them to have greater energy and to ascend in their 313 00:19:05,280 --> 00:19:08,760 Speaker 2: orbit and end up going into outer rings beyond that 314 00:19:08,960 --> 00:19:09,480 Speaker 2: little moon. 315 00:19:10,359 --> 00:19:12,959 Speaker 1: So again we have the Shepherd moons here. They were 316 00:19:13,000 --> 00:19:16,840 Speaker 1: discovered by Voyager two in nineteen eighty six. Like the 317 00:19:16,880 --> 00:19:19,080 Speaker 1: rest of Uranus's inner moons, they appear to be roughly 318 00:19:19,119 --> 00:19:23,239 Speaker 1: equal split of water, ice and rock. They're small. Of 319 00:19:23,320 --> 00:19:27,200 Speaker 1: note to Cordelia is the closest to the planet, and 320 00:19:27,520 --> 00:19:30,560 Speaker 1: I guess we should also point out or come back 321 00:19:30,560 --> 00:19:34,320 Speaker 1: to the fact that yes, these are both Shakespearean references. 322 00:19:34,520 --> 00:19:37,240 Speaker 1: There are going to be a lot of shakespeare references 323 00:19:37,320 --> 00:19:40,560 Speaker 1: as we go through the moons of Uranus, and these 324 00:19:40,560 --> 00:19:41,440 Speaker 1: are just the first two. 325 00:19:41,680 --> 00:19:43,600 Speaker 2: It seems that a lot of the names of these 326 00:19:43,640 --> 00:19:46,600 Speaker 2: satellites for some reason were chosen either from the works 327 00:19:46,600 --> 00:19:50,440 Speaker 2: of Shakespeare or from the works of Alexander Pope. 328 00:19:50,920 --> 00:19:55,680 Speaker 1: Yeah, predominantly Shakespearean, but definitely there's some key Alexander Pope 329 00:19:55,720 --> 00:19:58,159 Speaker 1: references as well. So as we go through it, we 330 00:19:58,240 --> 00:20:01,800 Speaker 1: can probably talk a little bit about some the namesakes here. 331 00:20:02,040 --> 00:20:04,359 Speaker 2: Well, this was something I was wondering. I don't know 332 00:20:04,359 --> 00:20:07,560 Speaker 2: about the origin exactly, like what people had in mind 333 00:20:07,640 --> 00:20:10,919 Speaker 2: when they were naming these, But so I think, like, 334 00:20:11,080 --> 00:20:15,480 Speaker 2: is there some significance to the innermost minor moon here 335 00:20:15,920 --> 00:20:20,800 Speaker 2: being called Cordelia, because Cordelia is a very poignant character. 336 00:20:21,080 --> 00:20:24,439 Speaker 2: Cordelia is the youngest daughter of King Lear in the 337 00:20:24,480 --> 00:20:26,359 Speaker 2: play King Lear. If you don't know the play or 338 00:20:26,440 --> 00:20:29,359 Speaker 2: need refreshing, the very beginning of it, the first scene 339 00:20:29,560 --> 00:20:32,960 Speaker 2: is King Lear is this old king. He comes out. 340 00:20:32,960 --> 00:20:35,800 Speaker 2: He decides that he will divide up his kingdom between 341 00:20:35,800 --> 00:20:40,560 Speaker 2: his three daughters, Goneril, Reagan, and Cordelia, and he's going 342 00:20:40,600 --> 00:20:43,680 Speaker 2: to give the largest portion to the daughter that loves 343 00:20:43,760 --> 00:20:48,080 Speaker 2: him most. So Goneril and Reagan give these speeches where 344 00:20:48,080 --> 00:20:52,159 Speaker 2: they overwhelm their father with absurd insincere flattery about how 345 00:20:52,200 --> 00:20:55,480 Speaker 2: much they love him. And then when it's Cordelia's time 346 00:20:55,520 --> 00:20:59,960 Speaker 2: to speak, she finds that she cannot put into words, 347 00:21:00,080 --> 00:21:03,879 Speaker 2: She cannot express her love for her father to herself. 348 00:21:03,920 --> 00:21:06,360 Speaker 2: She says that she knows her love is richer than 349 00:21:06,400 --> 00:21:09,040 Speaker 2: her tongue. And then when it's her time to speak, 350 00:21:09,080 --> 00:21:11,760 Speaker 2: she says, unhappy that I am. I cannot heave my 351 00:21:11,920 --> 00:21:15,520 Speaker 2: heart into my mouth. I love your majesty according to 352 00:21:15,560 --> 00:21:19,560 Speaker 2: my bond, no more nor less. And I think he 353 00:21:19,560 --> 00:21:22,639 Speaker 2: gives her a chance to amend her statement. She doesn't really, 354 00:21:22,720 --> 00:21:26,040 Speaker 2: and then so Lee gets furious at this decides to 355 00:21:26,080 --> 00:21:29,719 Speaker 2: disinherit her. He gives nothing to Cordelia, splits his kingdom 356 00:21:30,040 --> 00:21:33,840 Speaker 2: between the other two daughters, Goneril and Reagan, who secretly 357 00:21:33,920 --> 00:21:35,720 Speaker 2: think he is a fool and they will go on 358 00:21:35,800 --> 00:21:38,840 Speaker 2: to betray him once they come to power. And of 359 00:21:38,840 --> 00:21:41,439 Speaker 2: course it's a tragedy, so things just get worse and worries. 360 00:21:41,480 --> 00:21:44,600 Speaker 2: Basically everybody ends up dead but you know, it's a 361 00:21:44,720 --> 00:21:47,800 Speaker 2: very meaningful character and something I think, I don't know. 362 00:21:47,840 --> 00:21:50,439 Speaker 2: That moment in the first scene is something that always 363 00:21:50,440 --> 00:21:53,080 Speaker 2: got me, something I can really relate to, Like the 364 00:21:53,119 --> 00:21:59,359 Speaker 2: feeling of worrying that you don't express positive feelings because 365 00:21:59,400 --> 00:22:02,960 Speaker 2: you're afraid that you can't phrase them in the sincerest way, 366 00:22:03,040 --> 00:22:04,720 Speaker 2: like you don't know how to put them to words. 367 00:22:04,760 --> 00:22:07,320 Speaker 2: So then you worry that like you're perceived as not 368 00:22:07,400 --> 00:22:09,440 Speaker 2: wanting to say a positive thing at all. I don't 369 00:22:09,440 --> 00:22:10,680 Speaker 2: know if that makes sense. 370 00:22:11,400 --> 00:22:13,440 Speaker 1: No, no, no, no, I mean, certainly with the example 371 00:22:14,760 --> 00:22:17,320 Speaker 1: here from the play, absolutely. 372 00:22:17,160 --> 00:22:20,320 Speaker 2: But she's the daughter that truly loved him. She just 373 00:22:20,440 --> 00:22:23,679 Speaker 2: didn't want to give a big, insincere speech. 374 00:22:24,240 --> 00:22:24,640 Speaker 3: Anyway. 375 00:22:24,640 --> 00:22:26,680 Speaker 2: It's a very meaningful character. So I'm wondering, is there 376 00:22:26,760 --> 00:22:29,119 Speaker 2: some similarly at play here in the selection of the 377 00:22:29,200 --> 00:22:31,159 Speaker 2: name for this moon? Maybe not so, Like it's a 378 00:22:31,280 --> 00:22:35,159 Speaker 2: very small satellite, it's the closest to the planet of these. 379 00:22:35,320 --> 00:22:38,439 Speaker 2: It is one of the shepherd moons that sort of 380 00:22:38,840 --> 00:22:42,360 Speaker 2: guides the Epsilon ring and keeps it tight in formation. 381 00:22:43,359 --> 00:22:46,080 Speaker 2: By the end, I mean, she does show great discipline 382 00:22:46,119 --> 00:22:49,200 Speaker 2: because she comes back with an army to try to 383 00:22:49,200 --> 00:22:53,560 Speaker 2: to fight on her father's side against her cruel, duplicitous sisters. 384 00:22:54,200 --> 00:22:56,359 Speaker 2: I don't know, maybe not. I don't know if it fits, 385 00:22:56,400 --> 00:22:57,480 Speaker 2: but I was wondering. 386 00:22:58,320 --> 00:23:02,200 Speaker 1: No, I think it's natural to try and read some 387 00:23:02,240 --> 00:23:04,440 Speaker 1: sort of sense into the naming. 388 00:23:04,680 --> 00:23:04,880 Speaker 3: Though. 389 00:23:04,920 --> 00:23:07,439 Speaker 1: Of course, as we'll discuss it, it's different people at 390 00:23:07,440 --> 00:23:10,199 Speaker 1: different times coming up with these names. You know, some 391 00:23:10,320 --> 00:23:13,520 Speaker 1: are maybe probably a little more up on the works 392 00:23:13,520 --> 00:23:16,959 Speaker 1: of William Shakespeare than others. Sometimes there's there seems like 393 00:23:17,000 --> 00:23:19,199 Speaker 1: something they could be getting, at other times not. And 394 00:23:19,480 --> 00:23:23,159 Speaker 1: also some of these kind of slip by on a technicality, 395 00:23:24,040 --> 00:23:26,919 Speaker 1: so they're kind of all over the place. All right, 396 00:23:26,960 --> 00:23:29,720 Speaker 1: let's let's go into the next one. There's a Bianca 397 00:23:29,800 --> 00:23:33,200 Speaker 1: named after Kate's sister in the Taming of the Shrew. 398 00:23:34,160 --> 00:23:36,879 Speaker 1: This one does nothing really else that I think is 399 00:23:36,920 --> 00:23:39,840 Speaker 1: significant about it, and it was also discovered by Voyager two. 400 00:23:40,119 --> 00:23:42,679 Speaker 1: All right, after that, we have Cressida. This is the 401 00:23:42,680 --> 00:23:46,920 Speaker 1: title character from Troylus and Cresida. Again, nothing other else 402 00:23:46,960 --> 00:23:49,879 Speaker 1: it's really significant about this moon it was also discovered 403 00:23:49,880 --> 00:23:52,560 Speaker 1: by Voyger two. I know some of your probably wondering 404 00:23:52,560 --> 00:23:54,320 Speaker 1: when's Voyager six is going to show up in all this? 405 00:23:54,400 --> 00:23:57,280 Speaker 1: But I guess Voyger six just shot right out there, right. 406 00:23:58,400 --> 00:24:01,280 Speaker 2: I was unsure, but what you're for di vigure here? Right? 407 00:24:01,400 --> 00:24:01,720 Speaker 3: Yes? 408 00:24:01,960 --> 00:24:05,480 Speaker 1: Yeah, Voyager six doesn't actually exist except in the world 409 00:24:05,560 --> 00:24:09,000 Speaker 1: of Star Trek, okay, specifically Star Trek the motion picture, 410 00:24:09,280 --> 00:24:12,920 Speaker 1: the most riveting of all of them, that was pinned 411 00:24:12,960 --> 00:24:16,000 Speaker 1: by Alan Dean Foster. Oh wait, was he the one 412 00:24:16,040 --> 00:24:16,680 Speaker 1: who wrote. 413 00:24:16,480 --> 00:24:20,680 Speaker 2: The novelization of Halloween three or something like that? 414 00:24:21,640 --> 00:24:26,320 Speaker 1: He wrote the novelization of most films? Yes, all right. 415 00:24:26,480 --> 00:24:30,240 Speaker 1: The next moon of note here is Desdemona. This one's 416 00:24:30,280 --> 00:24:33,640 Speaker 1: named after the wife of Othello. No other real significance, 417 00:24:33,720 --> 00:24:36,840 Speaker 1: once again discovered by Voyager two. All right, now we're 418 00:24:36,840 --> 00:24:40,240 Speaker 1: moving on to another one. This is Juliet or Juliet 419 00:24:40,320 --> 00:24:42,919 Speaker 1: right if you're depending on how you're what line from 420 00:24:42,960 --> 00:24:45,520 Speaker 1: the play using sometimes you got to hit two syllables 421 00:24:45,840 --> 00:24:48,120 Speaker 1: instead of three on that. This is of course, named 422 00:24:48,119 --> 00:24:52,080 Speaker 1: after the title character from Romeo and Juliet. Romeo, meanwhile, 423 00:24:52,160 --> 00:24:54,960 Speaker 1: is nowhere to be found amid the moons of Uranus. 424 00:24:56,160 --> 00:24:58,520 Speaker 1: It is kind of interesting that there's a part in 425 00:24:58,640 --> 00:25:02,200 Speaker 1: Romeo and Juliet where Romeo is swearing his love up 426 00:25:02,240 --> 00:25:06,040 Speaker 1: and down the universe and Juliette specifically asked him not 427 00:25:06,119 --> 00:25:09,840 Speaker 1: to swear by the moon. She says, quote, oh, swear 428 00:25:09,920 --> 00:25:14,720 Speaker 1: not by the moon, the inconstant moon that monthly changes 429 00:25:14,800 --> 00:25:19,639 Speaker 1: in her circle orb less that thy love prove likewise variable. 430 00:25:19,480 --> 00:25:22,000 Speaker 2: Changes in her circle? Orb What does that refer to, 431 00:25:22,160 --> 00:25:25,359 Speaker 2: like the like waxing and waning of the moon or 432 00:25:25,440 --> 00:25:27,080 Speaker 2: maybe I'm not sure I know. 433 00:25:27,040 --> 00:25:27,600 Speaker 3: What that means. 434 00:25:28,119 --> 00:25:29,600 Speaker 1: I mean I take it to me and yeah, it's 435 00:25:29,640 --> 00:25:32,119 Speaker 1: like there are different faces of the moon, Like like 436 00:25:32,320 --> 00:25:35,879 Speaker 1: if your love is like the moon Romeo, then I 437 00:25:35,920 --> 00:25:37,320 Speaker 1: don't you know, it's like what am I going to 438 00:25:37,359 --> 00:25:39,879 Speaker 1: get today? I mean it seems like if it is 439 00:25:39,960 --> 00:25:41,439 Speaker 1: like the moon, she could chart it out and then 440 00:25:41,480 --> 00:25:43,480 Speaker 1: she'd have a really good idea of what she's gonna get, 441 00:25:44,680 --> 00:25:47,600 Speaker 1: you know, phase by phase. But yeah, she's like, I 442 00:25:47,640 --> 00:25:49,159 Speaker 1: need consistency. 443 00:25:48,840 --> 00:25:51,840 Speaker 2: Right, your love should not wax and wane. We shouldn't 444 00:25:51,880 --> 00:25:55,040 Speaker 2: have a new moon of your love. Yes, it's were 445 00:25:55,040 --> 00:25:56,080 Speaker 2: wolf night every night. 446 00:25:56,800 --> 00:25:57,800 Speaker 3: Yeah. 447 00:25:57,880 --> 00:26:02,000 Speaker 1: Anyway, Aside from these thoughts, juliet nothing else than literally 448 00:26:02,040 --> 00:26:06,520 Speaker 1: significant once again discovered by Voyger. Two, then we have Portia. 449 00:26:06,760 --> 00:26:09,280 Speaker 1: This one is named after the heroine from the Merchant 450 00:26:09,280 --> 00:26:12,399 Speaker 1: of Venice. This one. I guess the main significance is 451 00:26:12,400 --> 00:26:15,200 Speaker 1: that it orbits Urinus in less than one earth day, 452 00:26:15,640 --> 00:26:16,080 Speaker 1: and it. 453 00:26:16,040 --> 00:26:27,320 Speaker 3: Was discovered by Voyger two. All right. 454 00:26:27,400 --> 00:26:30,639 Speaker 1: Up, next we have Rosalind. Rosalind is one of the 455 00:26:30,760 --> 00:26:34,400 Speaker 1: Duke's daughters in As You Like It. That's the namesake. 456 00:26:34,760 --> 00:26:36,760 Speaker 1: Nothing else really significant to discuss here. 457 00:26:36,840 --> 00:26:39,800 Speaker 3: This one was also discovered by Voyager two. All right. 458 00:26:39,840 --> 00:26:44,439 Speaker 1: The next one is Cupid. This is this one? This 459 00:26:44,480 --> 00:26:47,359 Speaker 1: one is is a tough one to fit in, but okay. 460 00:26:47,400 --> 00:26:49,120 Speaker 1: Cupid is, of course the Roman god of. 461 00:26:49,119 --> 00:26:52,960 Speaker 2: Love, famously invented by William Shakespeare. 462 00:26:53,640 --> 00:26:59,480 Speaker 1: Well, he is technically a character in Shakespeare's what is 463 00:26:59,520 --> 00:27:02,760 Speaker 1: it timin Timon of Athens. I'm not familiar with this play. 464 00:27:03,000 --> 00:27:04,879 Speaker 1: I don't know anything about that one. This may be 465 00:27:04,920 --> 00:27:07,160 Speaker 1: one of the more obscure ones. I don't remember studying 466 00:27:07,160 --> 00:27:11,879 Speaker 1: this one in school. But the discovery of it is 467 00:27:11,960 --> 00:27:14,240 Speaker 1: kind of interesting because it was discovered by m R 468 00:27:14,480 --> 00:27:19,359 Speaker 1: Showalter in JJ Lissauer using the Hubble space telescope in 469 00:27:19,359 --> 00:27:22,680 Speaker 1: two thousand and three. It was too small and too 470 00:27:22,760 --> 00:27:25,960 Speaker 1: dark for Voyager two to spot. And I was thinking 471 00:27:25,960 --> 00:27:28,920 Speaker 1: about this. It's tempting to try and spin this one out. 472 00:27:28,960 --> 00:27:31,280 Speaker 1: And think of like, Okay, here we have Cupid as 473 00:27:31,320 --> 00:27:35,720 Speaker 1: this dark, near invisible shadow press presence, you know, reminding 474 00:27:35,800 --> 00:27:39,200 Speaker 1: us of past discussions about how Cupid was sometimes said 475 00:27:39,240 --> 00:27:41,840 Speaker 1: to shoot lead and arrows. So it's you know, he's 476 00:27:41,840 --> 00:27:45,080 Speaker 1: not only dealing out love with his projectiles, but also 477 00:27:45,600 --> 00:27:48,439 Speaker 1: some of the ramifications of love, and maybe even the 478 00:27:48,480 --> 00:27:53,840 Speaker 1: tragic ramifications of love. But again, this one, this one 479 00:27:53,840 --> 00:27:57,439 Speaker 1: seems to sort of slip by on a technicality in 480 00:27:57,520 --> 00:28:01,679 Speaker 1: terms of its naming. All right, the next one is Belinda, 481 00:28:02,520 --> 00:28:04,600 Speaker 1: And this is one where we have to just have 482 00:28:04,680 --> 00:28:06,840 Speaker 1: to ask Shakespeare to move over, because this one is 483 00:28:06,960 --> 00:28:10,760 Speaker 1: named after the character whose lock of hair is stolen 484 00:28:11,160 --> 00:28:13,600 Speaker 1: in Alexander Pope's Rape of the Lock. 485 00:28:14,160 --> 00:28:18,080 Speaker 2: Now, this is an unfortunately titled poem because it doesn't 486 00:28:18,080 --> 00:28:20,800 Speaker 2: mean what it sounds like. That the poem by Pope 487 00:28:20,960 --> 00:28:24,440 Speaker 2: is an older definition of the word rape, which is basically, 488 00:28:24,480 --> 00:28:28,840 Speaker 2: in this context it means like theft or snatching. So 489 00:28:28,880 --> 00:28:32,560 Speaker 2: the poem is a mock heroic satire. It narrates like 490 00:28:32,640 --> 00:28:35,920 Speaker 2: a social scandal in which a lord of some sort. 491 00:28:37,000 --> 00:28:38,800 Speaker 2: I did read this in school, and I forget a 492 00:28:38,800 --> 00:28:41,120 Speaker 2: lot of the details, but he steals a lock of 493 00:28:41,120 --> 00:28:44,120 Speaker 2: hair from a young woman. But it's written like in 494 00:28:44,160 --> 00:28:47,640 Speaker 2: the style of the Iliad, to be mocking of the like, 495 00:28:47,800 --> 00:28:51,400 Speaker 2: oh hoho, this is actually insignificant. I think Pope's point 496 00:28:51,520 --> 00:28:54,760 Speaker 2: is best summarized in one of its lines, where he says, 497 00:28:55,000 --> 00:28:59,000 Speaker 2: what mighty contests rise from trivial things? Though I don't know, 498 00:28:59,560 --> 00:29:03,080 Speaker 2: thinking on it now, there are obviously much worse crimes, 499 00:29:03,080 --> 00:29:04,960 Speaker 2: but stealing somebody's hair is pretty weird. 500 00:29:05,680 --> 00:29:08,480 Speaker 1: Yeah, Plus hair has magical connotations. They could be stealing 501 00:29:08,480 --> 00:29:10,920 Speaker 1: it to work some sort of magic. Maybe that's explored 502 00:29:10,920 --> 00:29:13,600 Speaker 1: in the poem. I don't know. I have a degree 503 00:29:13,600 --> 00:29:16,400 Speaker 1: in English, and I somehow managed to never read this poem. 504 00:29:16,760 --> 00:29:18,960 Speaker 1: I remember that, you know the course. I'm familiar with 505 00:29:19,080 --> 00:29:23,520 Speaker 1: the author's name and his popularity and importance in English literature, 506 00:29:23,520 --> 00:29:26,720 Speaker 1: but I remember this title would come up and I 507 00:29:26,720 --> 00:29:28,920 Speaker 1: would think, Oh, that doesn't sound like something I want 508 00:29:28,960 --> 00:29:33,000 Speaker 1: to read, not realizing that it's about hair theft Alexander Pope. 509 00:29:33,280 --> 00:29:36,840 Speaker 2: Everything I recall that he wrote is basically satirical in nature. 510 00:29:37,200 --> 00:29:40,320 Speaker 2: I'm sure he must have written serious poems, but like 511 00:29:40,360 --> 00:29:42,960 Speaker 2: the other main thing I remember he wrote is something 512 00:29:43,000 --> 00:29:47,200 Speaker 2: called the Dunceiad, which is a sort of an epic 513 00:29:47,240 --> 00:29:48,720 Speaker 2: poem about stupidity. 514 00:29:49,200 --> 00:29:49,440 Speaker 1: Hmm. 515 00:29:50,120 --> 00:29:52,040 Speaker 2: He was like, it seems like he was just really 516 00:29:52,040 --> 00:29:53,480 Speaker 2: into not suffering fools. 517 00:29:54,040 --> 00:29:54,200 Speaker 1: Though. 518 00:29:54,240 --> 00:29:56,400 Speaker 2: I feel like if that's your main vibe, you really 519 00:29:56,440 --> 00:29:59,120 Speaker 2: open yourself up to scrutiny, don't you. 520 00:30:01,080 --> 00:30:02,640 Speaker 1: All Right, well, we'll come back to Pope's work in 521 00:30:02,680 --> 00:30:05,440 Speaker 1: a bit, because there are more moons named after him. 522 00:30:05,800 --> 00:30:08,320 Speaker 1: The next one is Perdita, and this is the daughter 523 00:30:08,800 --> 00:30:13,800 Speaker 1: of Leontes and Hermione in William Shakespeare's The Winter's Tail. 524 00:30:14,880 --> 00:30:18,000 Speaker 1: This one's discovery is actually pretty interesting because Voyger two 525 00:30:18,040 --> 00:30:21,040 Speaker 1: is involved in its discovery, but it wasn't recognized till 526 00:30:21,040 --> 00:30:27,440 Speaker 1: two thousand and three. Basically, University of Arizona's Eric Karkoshka 527 00:30:27,720 --> 00:30:32,120 Speaker 1: discovered it by comparing Voyger two imagery with Hubble imagery 528 00:30:32,360 --> 00:30:34,959 Speaker 1: and sort of working out its existence based on these 529 00:30:35,000 --> 00:30:39,360 Speaker 1: two different streams. All right, up next, we have Puck Is, 530 00:30:39,360 --> 00:30:42,720 Speaker 1: of course, named after the sprite from A Midsummer Night's Dream. 531 00:30:43,400 --> 00:30:46,200 Speaker 1: Stanley Tucci played him in the nineteen ninety nine film adaptation, 532 00:30:46,280 --> 00:30:48,840 Speaker 1: which had a great cast. I do remember seeing this 533 00:30:48,880 --> 00:30:51,200 Speaker 1: film when it came out, and I imagine I've seen 534 00:30:51,280 --> 00:30:54,240 Speaker 1: multiple it seems like Midsummer Night's Dream is just one 535 00:30:54,240 --> 00:30:56,480 Speaker 1: of those plays that if you're just going to fall 536 00:30:56,480 --> 00:30:58,400 Speaker 1: into seeing it, even if you don't set out to 537 00:30:58,400 --> 00:30:59,640 Speaker 1: watch Shakespeare in life. 538 00:31:00,120 --> 00:31:03,360 Speaker 2: Puck's a great character, great mischief maker, the mischief maker 539 00:31:03,360 --> 00:31:05,760 Speaker 2: who brings wisdom, whether on purpose or not. 540 00:31:06,480 --> 00:31:11,800 Speaker 1: Yeah, yeah, Tucci was perfect casting. Now significance. Here is 541 00:31:11,880 --> 00:31:14,440 Speaker 1: the smallest of the inner moons, with a diameter of 542 00:31:14,480 --> 00:31:17,560 Speaker 1: about one hundred and fifty kilometers or about ninety miles, 543 00:31:18,040 --> 00:31:21,760 Speaker 1: And it was guess what discovered by voyager two? All right, 544 00:31:21,840 --> 00:31:24,880 Speaker 1: up next we have Mab. It's named after Queen Mab, 545 00:31:25,280 --> 00:31:28,760 Speaker 1: queen of the fair Folk and English folklore. She's mentioned 546 00:31:28,760 --> 00:31:31,760 Speaker 1: in Romeo and Juliet So and just mentioned. So it 547 00:31:31,880 --> 00:31:36,400 Speaker 1: just really really squeaks by on a technicality. I mean, 548 00:31:36,920 --> 00:31:38,640 Speaker 1: this is one of those situations where I feel like 549 00:31:38,800 --> 00:31:40,840 Speaker 1: I want to shout a little bit and be like, look, 550 00:31:40,880 --> 00:31:44,680 Speaker 1: there are a lot of names that are mentioned in Shakespeare, 551 00:31:44,800 --> 00:31:47,080 Speaker 1: and there are plenty of characters. I don't know why 552 00:31:47,200 --> 00:31:50,560 Speaker 1: Queen Mab seems like the ideal choice. 553 00:31:50,560 --> 00:31:53,160 Speaker 2: Here is there an inner moon named Julius Caesar? 554 00:31:56,040 --> 00:31:58,080 Speaker 1: No, but you know you could that would have been 555 00:31:58,080 --> 00:32:00,480 Speaker 1: a good one Caesar, right, But that's just off the 556 00:32:00,480 --> 00:32:00,920 Speaker 1: top of my head. 557 00:32:00,920 --> 00:32:02,120 Speaker 3: I'm not sure if there's some other. 558 00:32:03,680 --> 00:32:05,760 Speaker 1: Well, you know, I should also point out when you 559 00:32:05,800 --> 00:32:07,760 Speaker 1: start looking. And I didn't get into this in any 560 00:32:07,760 --> 00:32:12,240 Speaker 1: of my note taking, really, but there are individual features 561 00:32:12,280 --> 00:32:15,040 Speaker 1: on some moons that are likewise named after other things. 562 00:32:15,120 --> 00:32:18,040 Speaker 1: So it could be a Caeesar in there somewhere, you 563 00:32:18,080 --> 00:32:18,280 Speaker 1: know what. 564 00:32:18,360 --> 00:32:20,880 Speaker 2: Actually, I want to be fair, Even a lot of 565 00:32:20,920 --> 00:32:24,960 Speaker 2: the Shakespeare characters that we think of as more original 566 00:32:25,000 --> 00:32:29,480 Speaker 2: shakespeare characters are actually often from like adapted versions of 567 00:32:29,720 --> 00:32:32,600 Speaker 2: pre existing tales. Like a lot of Shakespeare's plays were 568 00:32:32,640 --> 00:32:36,480 Speaker 2: not wholly made up stories. They were based on something 569 00:32:36,520 --> 00:32:39,440 Speaker 2: from history or from an older story or another play, 570 00:32:39,560 --> 00:32:43,200 Speaker 2: or something right right, Like who would have thought of it? 571 00:32:43,280 --> 00:32:43,560 Speaker 1: You know? 572 00:32:43,680 --> 00:32:45,400 Speaker 2: Hamlet is the guy from the Northman. 573 00:32:48,400 --> 00:32:50,440 Speaker 1: Yeah, I mean, if you were around today, he'd be uh, 574 00:32:50,520 --> 00:32:53,160 Speaker 1: you know, he'd be in the MCU somewhere working on 575 00:32:53,320 --> 00:32:54,400 Speaker 1: a project. 576 00:32:55,560 --> 00:32:55,720 Speaker 4: Of it. 577 00:32:55,760 --> 00:32:59,680 Speaker 1: Anyway, Mab is the moon here. This one's discovered in 578 00:33:00,000 --> 00:33:03,400 Speaker 1: two thousand and three by show Alter and Lisaur using 579 00:33:03,440 --> 00:33:04,840 Speaker 1: the Hubble space telescope. 580 00:33:05,080 --> 00:33:08,240 Speaker 2: Interesting in fact, I came across while reading that article 581 00:33:08,280 --> 00:33:12,360 Speaker 2: by the NASA Goddard researcher Amy Simon. She writes that 582 00:33:12,760 --> 00:33:17,920 Speaker 2: Mab quote maybe generating a tenuous blue toned ring like 583 00:33:18,040 --> 00:33:21,880 Speaker 2: Enceladus does for Saturn's e ring, though the source currently 584 00:33:21,920 --> 00:33:23,000 Speaker 2: remains a mystery. 585 00:33:24,520 --> 00:33:26,480 Speaker 1: Well, you know that sounds kind of fitting for the 586 00:33:26,520 --> 00:33:27,680 Speaker 1: Queen of the fairy Folk. 587 00:33:27,880 --> 00:33:29,040 Speaker 3: So I do like that. 588 00:33:29,480 --> 00:33:31,320 Speaker 2: Well, I'm looking at the clock, and do you know 589 00:33:31,360 --> 00:33:35,000 Speaker 2: what the clock reads. It reads a promise broken because 590 00:33:35,040 --> 00:33:36,760 Speaker 2: we said we were going to do all of the 591 00:33:37,200 --> 00:33:39,680 Speaker 2: moons within part two, and I think we have failed 592 00:33:39,680 --> 00:33:41,880 Speaker 2: because we're coming up against a time limit. We got 593 00:33:41,920 --> 00:33:44,480 Speaker 2: to cap it here and we've got all of the 594 00:33:44,560 --> 00:33:46,840 Speaker 2: major moons left to talk about. So I think that's 595 00:33:46,840 --> 00:33:49,280 Speaker 2: going to have to be part three of our series 596 00:33:49,280 --> 00:33:51,200 Speaker 2: on Uranus and its satellites. 597 00:33:51,720 --> 00:33:51,920 Speaker 3: Yeah. 598 00:33:52,000 --> 00:33:54,560 Speaker 1: Yeah, hopefully we didn't mess anybody up there, But I 599 00:33:54,600 --> 00:33:57,360 Speaker 1: think the journey will be better for breaking into three 600 00:33:57,400 --> 00:33:59,040 Speaker 1: parts here, and there's gonna be a lot of fun 601 00:33:59,080 --> 00:34:01,760 Speaker 1: stuff to talk about, especially with the major moons of 602 00:34:01,920 --> 00:34:04,760 Speaker 1: Uranus and then getting also into just some of the 603 00:34:04,760 --> 00:34:06,880 Speaker 1: additional Shakespearean. 604 00:34:06,240 --> 00:34:08,960 Speaker 3: References in the naming of these moons. 605 00:34:09,719 --> 00:34:12,560 Speaker 1: In the meantime, if you would like to catch up 606 00:34:12,560 --> 00:34:15,280 Speaker 1: on past episodes of Stuff to Blow Your Mind, including 607 00:34:15,280 --> 00:34:20,080 Speaker 1: our past episodes dealing with the moons of Jupiter and 608 00:34:20,200 --> 00:34:23,560 Speaker 1: Saturn and Mars and so forth.
