Speaker 1: When you wish on the star makes a lot of difference,
Speaker 1: or anything your heart desires.
Speaker 2: Will come to.
Speaker 3: How are you young, Mathew?
Speaker 2: Good?
Speaker 3: How are you getting their mate?
Speaker 2: It's sounding better, you might hear.
Speaker 4: I might have a remnants of a cold that I
Speaker 4: had last week.
Speaker 2: So oh did you?
Speaker 1: Yeah?
Speaker 2: Yeah, and this man.
Speaker 5: Flew It's awful stuff in that I know, and the
Speaker 5: girls do not understand how debilitating it can be.
Speaker 2: Well it was really wasn't that debilitating? I did.
Speaker 4: There was a bit of aurora last last Sunday, so
Speaker 4: the smart person in me decided, well, I'm massively sick,
Speaker 4: but I still need to get footage of the aurora,
Speaker 4: So where do you go? I went to Voyage in
Speaker 4: Rock near Brooklyn, and when I got there, after driving
Speaker 4: an hour and a half out there, realized I was
Speaker 4: the only person there. And I only realized that after
Speaker 4: I'd finished walking about fifteen minutes with a cold, having
Speaker 4: the camera taking photos going It's probably not the most
Speaker 4: smartest decision I've ever made, so it took about another
Speaker 4: five minutes. Once I'd finished, I was there for about
Speaker 4: just over now. Thankfully the aurora was there, because it
Speaker 4: would have been a long drive home and spent another
Speaker 4: probably extra five minutes trying to find out where I
Speaker 4: had got onto the rock because there is one path
Speaker 4: in and one path.
Speaker 2: Out from the rock, and it was very very dark.
Speaker 2: Does the cloud cover over?
Speaker 3: So where did this aurora come from in the first place?
Speaker 4: So we got there was a sun sport that sent
Speaker 4: out a solar flare, and that's sent that solar flare
Speaker 4: launched a coronal mass ejection. That was Sat Day that
Speaker 4: May thirty first, and it took just over a day
Speaker 4: and a bit because it was very very fast to hit,
Speaker 4: and so the East Coast and New Zealand got a
Speaker 4: really good show. And then unfortunately, we need the polarity
Speaker 4: of the of the magnetic field of the storm to
Speaker 4: be negative so that it can interact. Get can easily
Speaker 4: get into the magnetic field of the Earth because it's
Speaker 4: a positive charge, and unfortunately it was once it got
Speaker 4: once we got into nighttime, it moved into the positive phase,
Speaker 4: so we kind of didn't get the best of it,
Speaker 4: which was pretty much a shame. So I think it's
Speaker 4: got some decent.
Speaker 1: Take it.
Speaker 2: To get there took about an hour and a half.
Speaker 4: I was there for about an hour just by with
Speaker 4: myself and my thoughts and looking at this amazing milky
Speaker 4: way in the EMU and the night sky with the aurora,
Speaker 4: so I got some really good shots.
Speaker 5: So it's just the bizarre cosmic object or is it
Speaker 5: something totally.
Speaker 4: Do This is something completely different and it's actually Western
Speaker 4: Australian discovery as well. So astronomers at EKRA have been
Speaker 4: using the ASKAP it's the Australian Square Kilometer Array to
Speaker 4: discover there was this object that they look for transient events,
Speaker 4: So these are events that they blink on and off
Speaker 4: and sometimes they're quite long, sometimes they're quite short, so
Speaker 4: normally they're called fast radio bursts, but this one's quite
Speaker 4: interesting and they actually ended up having to use the
Speaker 4: Chandras Seika X ray observatory and also Issa's XMM Newton telescope,
Speaker 4: and it was using this transient event was actually sending
Speaker 4: out extremely regular X ray bursts every twenty minutes that
Speaker 4: lasted up to seven minutes, which is unusual for any
Speaker 4: non object that we know of. It was about fifteen
Speaker 4: thousand light years away in the direction of the constellation
Speaker 4: Scotum the shield, so it's at the legs of the
Speaker 4: EMU and the said tis arm. So what could it
Speaker 4: essentially be. Well, it's not a pulsar because it's too slow.
Speaker 4: So pulsars rotate, you know, the crab pulsar. The one
Speaker 4: in the crab nebula rotates thirty times a seconds, but
Speaker 4: we've seen ones that rotate thousands of times a second.
Speaker 4: It wasn't a typical black hole or a white dwarf
Speaker 4: that just didn't expect the behavior. It could be a
Speaker 4: highly magnetized white dwarf, a dense pack compact star remnant
Speaker 4: with an intense magnetic field, which would be kind of
Speaker 4: be like what our sun will end up being. It's
Speaker 4: too big to go, it's too small to be a
Speaker 4: blow up and be a soup and over on neutron star,
Speaker 4: it could be as a binary system where a magnetized
Speaker 4: white dwarf or a neutron star is orbiting around another star.
Speaker 4: But they actually think it might actually be an ultra
Speaker 4: long period magnetar. So these is another type of neutron
Speaker 4: star that spins extremely slowly, but it has a really
Speaker 4: really strong magnetic film. So yeah, so there's two flavors
Speaker 4: of neutron stars. So these are stars that are really
Speaker 4: really big, but they when they blow up, they're not
Speaker 4: big enough to form a black hole, so all of them,
Speaker 4: if you can remember your high school physics, you've got
Speaker 4: the proton and neutrons in the middle of the atom,
Speaker 4: and then you've got the electrons moving around to them,
Speaker 4: and so the protons are the positive charge, the electrons
Speaker 4: are the negative charge. Well, they get squeezed so much
Speaker 4: in the collapse of the star that they all be
Speaker 4: they form neutron stars. So you basically get this star
Speaker 4: of neutrons. And so there's two types. There's a pulsar
Speaker 4: where it keeps the rotational menum of the star when
Speaker 4: it was millions of kilometers wide, but it's only about
Speaker 4: twenty kilometers across, so it look acts like a little
Speaker 4: bit like a lighthouse, and you can actually use them
Speaker 4: to navigate because they're precise. And then you've got these magnetars,
Speaker 4: which they have ultra dense strong magnetic fields. They have
Speaker 4: like a crust, and they even done some sos where
Speaker 4: you can actually have mountains, but those mountains are like
Speaker 4: one centimeter because if you take a teaspoon of neutron material,
Speaker 4: it's the same wait as Mount Everest. Oh yeah, goodness, yeah,
Speaker 4: it's pretty dense, like you don't want to click your
Speaker 4: fingers and just appear on a pulsar or a magnetar
Speaker 4: because you just go, I.
Speaker 3: Love the quote you've got here.
Speaker 5: It's like the universe left us a cosmic mystery postcard
Speaker 5: and we're still trying to figure out who you said.
Speaker 5: We're going to take a break and then if you'd
Speaker 5: like to have a chat by the way to Matt,
Speaker 5: he'd love to have a chat to you, one double
Speaker 5: three eight eighty two. But we're going to just examine
Speaker 5: this Milky with the Andromeda collision, which we're told, and
Speaker 5: Matt will expand on this may not happen at all.
Speaker 3: Until midnight on Perth six PR.
Speaker 2: This is remember when with Harvey Digan.
Speaker 3: Matt Ward's from the Perth Observe.
Speaker 5: He's in the studio with us, and we've been looking
Speaker 5: over our shoulder, haven't we, because we've been expecting the
Speaker 5: Milky Way to smash into the Andromeda Galaxy pretty soon,
Speaker 5: like in five billion years.
Speaker 2: Yeah, only five billion years.
Speaker 3: So if it hasn't happened, it may not happen.
Speaker 5: No.
Speaker 4: So for people who like me who plan to live forever,
Speaker 4: it's just you you just have to sit and wait.
Speaker 4: But yeah, so the theory has always been that it's
Speaker 4: heading on for a head on collision, and that's been
Speaker 4: for decades. We've thought about that since we've actually known
Speaker 4: that the Andromeda galaxy is actually not part of our galaxy.
Speaker 4: It's Edwin Hubble realized that the great Nebula of Oryan
Speaker 4: was actually another galaxy. And then when they were doing
Speaker 4: this thing, they could actually measuring how far away was
Speaker 4: they could actually see there was blue blue shifted, so
Speaker 4: the light was more in the blue spectrum the light,
Speaker 4: and so that meanut's coming straight for us or coming
Speaker 4: our way. And this is basically because you've got the
Speaker 4: local group of galaxies about one hundred galaxies, and they
Speaker 4: keep themselves pretty much together. And new research coming from
Speaker 4: the European Space Agency's Gaya space telescope, which has just
Speaker 4: retired this year, actually suggests that it might entirely miss us,
Speaker 4: or it might actually only result in a glancing blow.
Speaker 4: So this cataclysmic merger that we think might actually happen
Speaker 4: might actually just only be simply graze one another and
Speaker 4: continue on and reshaped, but not destroyed. So why the
Speaker 4: thinking change is that the Gaya data has been provided
Speaker 4: a more accurate three D motion of measurement of the
Speaker 4: stars in Androma, and it turns out that Andromeda actually
Speaker 4: has more sideways motions, say like a car changing lanes
Speaker 4: rather than heading straight for us. So maybe it's maybe
Speaker 4: it's seen us coming and like just indicated to get
Speaker 4: into the different lane. Now it just has to decide
Speaker 4: who is the one in the wrong lane?
Speaker 2: Are we in the wrong lane or.
Speaker 3: At least they've got a little bit of time to
Speaker 3: sort it out now.
Speaker 4: Well, if they're following, if they're following Australian and British
Speaker 4: Commonwealth Countries road rules, then essentially it's it's in the
Speaker 4: wrong lane. And so that change is predicted has changed
Speaker 4: the predicted interaction modeling, so it'll be more like two
Speaker 4: dances brushling past each other than a full on crash
Speaker 4: as well, so think of it less like a car
Speaker 4: crash and more like a near miss at an intersection.
Speaker 4: So hopefully we'll still have a dashcam footage. They can
Speaker 4: give it to dash cams Australia, so yeah, hope they will. Yeah,
Speaker 4: what's the ladest with Starship? So they have so they
Speaker 4: did back on May the twenty seventh launched Flight nine,
Speaker 4: where was the first use of reuse of a super
Speaker 4: heavy booster, and the booster was successfully launched and it
Speaker 4: broke apart approximately six and a half minutes into the mission,
Speaker 4: which was during the landing burn phase. It wasn't expected
Speaker 4: to be caught again. It was going to land in,
Speaker 4: it was going to have a hard splash in the
Speaker 4: Gulf of America just because they were going to be
Speaker 4: doing some more experiments on it. Unfortunately, they're still having
Speaker 4: issues with Starship. So you have to understand that they
Speaker 4: were having the first lot of starships that re entered
Speaker 4: were the first generation of Starship, and so this one
Speaker 4: is an upgraded version, so this is two point zero,
Speaker 4: so they're still trying to work out the bugs from it.
Speaker 4: But now they're actually just starting the test firing of
Speaker 4: the super heavy for the tenth flight. So that happened
Speaker 4: on during the sixth at Boka Chica, which is SpaceX's
Speaker 4: star based facility in southern Texas, and so it fired
Speaker 4: all thirty three Raptor engines from the super heavy booster.
Speaker 4: So it's looking like maybe in the next few weeks
Speaker 4: to a month or two that we'll get another Starship launch,
Speaker 4: which is I think, you know, it just shows that,
Speaker 4: you know, hopefully it all works. So it's just one
Speaker 4: of those things that SpaceX has used the rapid prototyping
Speaker 4: method of just build it, get it up there quickly,
Speaker 4: if it fails, work out why it failed, and then
Speaker 4: just fixed the other ones before sending them up again.
Speaker 4: So it means it's either successful successful or you get
Speaker 4: a pretty spectacular rapid unscheduled assembly.
Speaker 3: And of course no human lives will be put at
Speaker 3: risk in this, no.
Speaker 2: Tiny bits and pieces of all.
Speaker 4: With the flight I think Flight Tests seven, which blew
Speaker 4: up was the first of the monster blow did have
Speaker 4: a banana in it. Unfortially we lost the first banana
Speaker 4: in space was was lost. So but yeah, so but yeah,
Speaker 4: And as Ming was saying about the Tetris, I have
Speaker 4: to say my packing ability for my car and for
Speaker 4: my house and that that came from Tetris as well.
Speaker 4: So how do they interface. I don't get it. Well,
Speaker 4: the Tetris, well, you know you've got to you've got
Speaker 4: to have your eye working out where you're going to
Speaker 4: put that little bit. So yeah, so when I look
Speaker 4: at my car space and my boot on my car,
Speaker 4: I just start to think tetris so yeah, so yep.
Speaker 3: Right.
Speaker 4: And as a former website developer as well, you.
Speaker 5: Yes, you've been hiding your talent behind a bushel on
Speaker 5: that one, haven't you?
Speaker 2: Stage ming no one korn So I can't tell you.
Speaker 4: The worst website I ever saw was we had a
Speaker 4: company that came to the with a website that hadn't changed.
Speaker 2: This was in the.
Speaker 4: Early late two late two thousands, early twenty tens. It
Speaker 4: was Oh, she's looking, but das yes, I might not
Speaker 4: get out.
Speaker 2: Of here lives. This is when I'm engaged.
Speaker 3: You have a rival, you shouldn't go into business against jud.
Speaker 2: It was it was still table based.
Speaker 4: So when me and I first built our websites, you
Speaker 4: built tables. Labels were still tables. And this was when
Speaker 4: the smartphones first came out, So all of a sudden,
Speaker 4: there's this revolution of mobile responsiveness. So you had to
Speaker 4: make sure the website broke down and so it was visible.
Speaker 4: This thing was mobile responsive before mobile responsive.
Speaker 3: Amazing, well, wonderful stuff.
Speaker 5: Now before you go, what's happening at the observatory and
Speaker 5: how can people switch on to what is happening?
Speaker 3: And you know, learn a bit more about the stars.
Speaker 4: Well, we're into Milky Way season now, so you do
Speaker 4: have to book in advance. She's slowly going. It could
Speaker 4: be troubles here, so if you want to come and
Speaker 4: have a look at the amazing and the night sky,
Speaker 4: highly suggest you book in that. We've still got spots
Speaker 4: in August. We've got our Astronomy one O two course
Speaker 4: which is starting this Wednesday. I think we've still got
Speaker 4: a couple of spots left. And we do actually have
Speaker 4: a whole bunch of astrophotography exhibitions and as workshops that
Speaker 4: I've put up on the website in there's September, October
Speaker 4: and November ones and you can book through the website there.
Speaker 5: So fantastic stuff. All right, Well, I'm going to let
Speaker 5: you two go and just sort all listeners.
Speaker 2: Pray for me.
Speaker 5: I got five dollars each way on ming mate coming
Speaker 5: up after the news. Billy Panell
