Space Force Secrets, Stellar Speedsters, and Cosmic Communication: S04E47

0:00 Speaker 1: Welcome again to Astronomy Daily. I'm Steve Dunkley, your human host.

0:04 Speaker 1: It's the twenty fourth of February twenty twenty five.

0:09 Speaker 2: Podcast.

0:11 Speaker 1: I mean to be your whole Steve Dunkle. Oh, yes,

0:16 Speaker 1: and thank you for joining us here at Astronomy Daily.

0:18 Speaker 1: Come to you from the studio in Paradise. That's right, Newcastle, Australia.

0:22 Speaker 1: Currently thirty six degrees. I'm so glad to be indoors.

0:26 Speaker 1: That's Celsius for all of you who are wondering, it's

0:28 Speaker 1: a perfect summer's day here on Australia's beautiful East Coast.

0:32 Speaker 1: Not a cloud in the sky. The sun is baking us. Yes,

0:36 Speaker 1: and as dylanor And once said, we're all audibly crackling

0:40 Speaker 1: down here. We're only three kilometers from the surface of

0:44 Speaker 1: the sun. Didn't you know that it is hot? Hot hot?

0:48 Speaker 1: And joining me again is my digital reporter Pale, who's

0:51 Speaker 1: fun to be with.

0:51 Speaker 3: Welcome back, Holle, Hi favorite human. What's new?

0:55 Speaker 1: Oh, Hally, just another week in the real world, just

0:58 Speaker 1: enjoying all the news from the Astronomy Daily newsletter. Now

1:01 Speaker 1: have you found your stories for today?

1:03 Speaker 2: Yes?

1:04 Speaker 3: I have. You'll like one about the mysterious Space Force

1:06 Speaker 3: space plane.

1:07 Speaker 1: I'll stop it. Space Force. You know what that means?

1:10 Speaker 3: Yes, your favorite.

1:12 Speaker 1: Oh people, get ready the Space.

1:13 Speaker 3: Force theme music.

1:14 Speaker 1: Space Oh dear, I'll just click myself out. And what

1:20 Speaker 1: else have you got for us? Helle?

1:21 Speaker 3: Oh? Yes, SpaceX has completed a substantial static fire test

1:27 Speaker 3: that I'll also report on. That sounds very good, It

1:29 Speaker 3: looks promising.

1:30 Speaker 1: That's great, Halle. It's not Space Force, but it's really good.

1:34 Speaker 1: And I am going to have a look at a

1:36 Speaker 1: fast moving star astronomers have discovered toward the center of

1:39 Speaker 1: the galaxy. And you won't believe just how fast we're

1:42 Speaker 1: talking with this one.

1:43 Speaker 3: How fast are we talking?

1:45 Speaker 2: Then?

1:45 Speaker 1: Well, helly, remember that time you asked me to put

1:47 Speaker 1: away the memory cards from the recording sessions last year.

1:50 Speaker 3: Yes, and I'm still waiting anything to get out of

1:53 Speaker 3: a little work.

1:54 Speaker 1: Yeah. Okay, Well this star is way faster than that.

1:56 Speaker 3: Okay, okay, that's pretty quick, tell you.

2:00 Speaker 1: Listeners, she said, not very convincingly.

2:03 Speaker 3: That's a fact.

2:04 Speaker 1: Yeah. Okay, enough of that, Shenantigan's. But before we get

2:08 Speaker 1: stuck into today's stories, Halle, I've got a quick update

2:10 Speaker 1: regarding that approaching asteroid that's been in.

2:13 Speaker 3: The news lately, the one causing all the rumors about

2:16 Speaker 3: certain destruction in twenty thirty two years.

2:18 Speaker 1: That's the one halle straight off the wire today. Asteroid

2:22 Speaker 1: twenty twenty four y are four, as listeners might be

2:25 Speaker 1: already aware, as a recently discovered near Earth object currently

2:30 Speaker 1: being closely monitored by NASA's Planetary Defense teams. Initial observations

2:34 Speaker 1: suggested there might be a potential risk of impact with

2:37 Speaker 1: Earth in the future, but thankfully updated calculations have significantly

2:41 Speaker 1: reduced this possibility. Based on the latest data, the asteroid

2:45 Speaker 1: has an extremely low probability point two eight percent of

2:50 Speaker 1: impacting Earth. On December twenty two, twenty thirty two. However,

2:54 Speaker 1: its chances of colliding with the Moon have slocally increased

2:57 Speaker 1: to one percent.

2:59 Speaker 3: So I can see that the asteroid's orbit continues to

3:01 Speaker 3: be refined through ongoing observations, with NASA's Jet Propulsion Laboratory

3:05 Speaker 3: CENTURY system providing real time updates on its trajectory.

3:09 Speaker 1: That is exactly how it works, and while Asteroid twenty

3:12 Speaker 1: twenty four four doesn't currently pose a significant threat, scientists

3:16 Speaker 1: are remaining vigilant tracking its movements to give more accurate

3:19 Speaker 1: predictions into as says, any potential future risks just in case.

3:24 Speaker 3: That's very wise, and this is why we shouldn't jump

3:27 Speaker 3: to conclusions about trajectories and potential impacts so soon.

3:30 Speaker 1: That's right. The asteroid is a near Earth object of

3:33 Speaker 1: the Apollo type with a estimated diameter between forty and

3:37 Speaker 1: ninety meters, and it was discovered on December twenty seven,

3:40 Speaker 1: twenty twenty four by Atlas, which is the Asteroid Terrestrial

3:43 Speaker 1: Impact Last Alert System at its Chilean station in Rio Hutundo.

3:49 Speaker 3: So nothing to be concerned about, after all, nothing at all.

3:52 Speaker 1: But who knows, we might get to see a spectacular

3:55 Speaker 1: impact on the Moon.

3:56 Speaker 3: Maybe perhaps maybe wouldn't that be something?

4:00 Speaker 1: And it's good today that Atlas is watching the skies.

4:03 Speaker 3: Thanks for that update, human, Now shall we just launch

4:07 Speaker 3: into the episode.

4:07 Speaker 1: Then good idea hit the Gothene Rhightoh.

4:16 Speaker 3: Last week, Ship thirty four completed its engine testing campaign

4:19 Speaker 3: with a long duration static fire. This static fire was

4:23 Speaker 3: nearly a minute long, and according to SpaceX, the extended

4:26 Speaker 3: firing tested new hardware and cycled the six Raptor engines

4:29 Speaker 3: through multiple thrust levels to recreate different conditions seen within

4:32 Speaker 3: the propulsion system during flight. Data from the test will

4:36 Speaker 3: inform upgrades to the ship's hardware and flight profile ahead

4:39 Speaker 3: of the next launch. The new hardware that SpaceX tested

4:43 Speaker 3: was likely related to the anomaly that occurred during flight

4:46 Speaker 3: seven and resulted in the loss of Ship thirty three.

4:49 Speaker 3: This could have been a leak in the liquid oxygen

4:51 Speaker 3: and liquid methane supply lines to the engines, which could

4:54 Speaker 3: have been the source of the fire scene during Ship

4:56 Speaker 3: thirty three's ascent burn. However, there is no official comp

5:00 Speaker 3: information from SpaceX regarding the actual cause of the failure.

5:04 Speaker 3: This test was also done to inform of other upgrades

5:06 Speaker 3: to the vehicle and possible changes to the flight profile,

5:09 Speaker 3: so it is likely that SpaceX still has modifications to

5:12 Speaker 3: be made on Ship thirty four. It is unclear what

5:15 Speaker 3: these modifications could be or how long it will take

5:18 Speaker 3: SpaceX to implement them on Ship thirty four. This long

5:21 Speaker 3: duration static fire is the longest SpaceX has ever fired

5:24 Speaker 3: a starship or booster on the ground, and it can

5:27 Speaker 3: do this because of the flame trench at Massy's It

5:30 Speaker 3: is unclear if this will be a one time test

5:32 Speaker 3: or if crews will do longer duration static fire in

5:35 Speaker 3: the future. There are a few things that SpaceX will

5:38 Speaker 3: likely add to the flight, considering several things couldn't be

5:41 Speaker 3: tested on flight seven. Firstly, there are the dummy starlinks

5:45 Speaker 3: which were loaded into Ship thirty three. A new batch

5:47 Speaker 3: of them was seen in star Factory to be presumably

5:50 Speaker 3: loaded on Ship three four just before rollout to the

5:52 Speaker 3: launch site. SpaceX might use the new starlink loader box

5:56 Speaker 3: that was built inside High Bay rather than the tray

5:58 Speaker 3: loader used on Ship Fife thirty three. As for the

6:02 Speaker 3: other items expected to be added to Ship thirty four,

6:04 Speaker 3: there is the actively cool tile for testing, as well

6:07 Speaker 3: as the catch pins. These catch pins are likely to

6:10 Speaker 3: be just bolted on, as SpaceX does not intend to

6:12 Speaker 3: catch Ship thirty four. Lastly, crews will likely remove all

6:16 Speaker 3: of the tiles that were removed on Ship thirty three

6:18 Speaker 3: to help understand the limits of losing a tile in

6:21 Speaker 3: certain places during re entry. An interesting note about Ship

6:25 Speaker 3: thirty four's engine testing campaign is it took SpaceX seventy

6:28 Speaker 3: two hours to roll it to massi's static fire it

6:31 Speaker 3: and then roll it back to Mega Bay two. This

6:34 Speaker 3: is a record compared to every other ship in the past.

6:37 Speaker 3: Booster fifteen was static fired on February ninth, and it

6:40 Speaker 3: was just the normal ten second static fire with all

6:43 Speaker 3: thirty three engines. With this out of the way, SpaceX

6:46 Speaker 3: rolled the booster back into Mega Bay one for final

6:49 Speaker 3: checkouts and has since received its hot stage train. SpaceX

6:53 Speaker 3: completed the rollout mount on the orbital launch mount and

6:56 Speaker 3: roll back of the booster in just over sixty one hours,

6:58 Speaker 3: which is a new record for bos bosters. This booster

7:02 Speaker 3: doesn't have any major outside changes that are noticeable, but

7:05 Speaker 3: it was the first booster to have the added tanks

7:07 Speaker 3: on the landing tank, but older boosters were likely retrofitted

7:11 Speaker 3: with this upgrade. The final two pieces of the puzzle

7:14 Speaker 3: for flight eight are the launch pad and the regulatory side. First,

7:19 Speaker 3: SpaceX has finally found a rhythm with refurbishing orbital launch

7:22 Speaker 3: pad A, which takes about two to three weeks to

7:24 Speaker 3: refurbish for a booster static fire. Then we will have

7:28 Speaker 3: another few weeks to get it ready for launch again.

7:31 Speaker 3: The second piece is waiting for the mishap investigation to

7:34 Speaker 3: be completed. So far there is no indication of when

7:37 Speaker 3: this might be completed. However, given the post SpaceX made

7:40 Speaker 3: after the long Durationship thirty four static fire. The final

7:44 Speaker 3: part of that investigation could be nearing a close. The

7:47 Speaker 3: next thing to watch out for is a SpaceX post

7:49 Speaker 3: detailing the anomalies, cost, and the fixes they are implementing.

7:53 Speaker 3: The Federal Aviation Administration will also likely post about approving

7:57 Speaker 3: Starship for return to flight after the completed Invents instigation.

8:01 Speaker 3: If SpaceX follows the same trajectory and splash down locations,

8:05 Speaker 3: the license that is currently issued for Starship should still

8:07 Speaker 3: be current. Currently, there is a notice to airmen from

8:11 Speaker 3: Mexican Airspace for February twenty six, with a window of

8:14 Speaker 3: six thirty pm to eight or nine pm Central Standard Time.

8:18 Speaker 3: With all this in mind, SpaceX still has a lot

8:20 Speaker 3: of work to do to launch Flight eight in less

8:22 Speaker 3: than a week.

8:23 Speaker 1: Astronomy Vodka. If you're going to call aliens, you'd better

8:29 Speaker 1: use this number. Let's dive into one of those cosmic

8:32 Speaker 1: curiosities that's bound to blow your mind. Have how about

8:36 Speaker 1: we call some aliens in chat No, and not talking

8:39 Speaker 1: about elaborate coded messages or flashy signals. We're talking about

8:42 Speaker 1: something incredible, incredibly fundamental twenty one centimeter radiation. And if

8:48 Speaker 1: you're planning on having a conversation across the vastness of

8:50 Speaker 1: space using light waves or electromagnetic radiation. It's pretty much

8:56 Speaker 1: your go to option. It's fast, reliable, and well it's

9:00 Speaker 1: most practical way to shout out to other civilizations in

9:03 Speaker 1: the universe. But why specifically twenty one centimeters? Well, that's

9:07 Speaker 1: where things get juicy. This twenty one centimeter radiation isn't

9:11 Speaker 1: just some random frequency we've picked out of a hat.

9:14 Speaker 1: It's tied to something very essential, known as the hydrogen

9:17 Speaker 1: spin flip. Hydrogen atoms consist of one proton and one electron.

9:22 Speaker 1: These tiny particles have a property called spin. Think of

9:26 Speaker 1: spin like a little arrow pointing up or pointing down.

9:30 Speaker 1: Every so often in the vast reaches of space, hydrogen

9:33 Speaker 1: atoms electron can flip its spin, going from a state

9:37 Speaker 1: where its spin is aligned with the proton to one

9:41 Speaker 1: pointing in the opposite direction. This flip releases energy in

9:44 Speaker 1: the form of radiation at you guessed it a wave

9:47 Speaker 1: length of twenty one centimeters. So why does this matter? Well,

9:52 Speaker 1: any smart civilization, whether they have blue skin, tentacles or

9:56 Speaker 1: something more bizarre, will eventually discover hydrogen. Understand that spin

10:01 Speaker 1: dabble in quantum mechanics and figure out this whole twenty

10:04 Speaker 1: one centimeter radiation thing, and they might call it something different.

10:09 Speaker 1: They won't have twenty one or maybe centimeters, but the

10:13 Speaker 1: concept remains universal. It's like it's like the cosmic Rosetta stone.

10:18 Speaker 1: What makes twenty one centimeter radiation perfect for long distance

10:22 Speaker 1: interstellar chats is its ability to cut through into stellar dust.

10:27 Speaker 1: Space is filthy with dust clouds that block out other

10:30 Speaker 1: forms of light. However, twenty one centimeter waves are like

10:34 Speaker 1: the VIPs of the universe, slipping through velvet ropes of

10:38 Speaker 1: cosmic debris to carry their message far and wide. Is

10:41 Speaker 1: the fun fact. NASA's Pioneer spacecraft, launched in the early

10:45 Speaker 1: nineteen seventies, carry plaques, and on these pluks there's a

10:49 Speaker 1: handy diagram of the hydrogen spin flip transition. All other

10:53 Speaker 1: measurements on the plaque, including the height of humans, are

10:56 Speaker 1: made in reference to this fundamental distance. I hope is

11:00 Speaker 1: that aliens can recognize the hydrogen spin flip transition and

11:04 Speaker 1: use that to unlock the rest of our message. Now

11:07 Speaker 1: imagine this scenario. One day, astronomers on Earth detect an

11:10 Speaker 1: unusual surge of twenty one centimeter radiation, and it's not

11:14 Speaker 1: coming from a random hydrogen cloud. It's directional, purposeful, and

11:18 Speaker 1: that could very well be an alien civilization sending us

11:22 Speaker 1: a what's up across the cosmos? A twenty one centimeter

11:26 Speaker 1: radiation makes for a great calling card. Using twenty one

11:30 Speaker 1: centimeter radiation to communicate with extraterrestrial beings leverages a basic

11:36 Speaker 1: universal constant. And who knows, maybe one day, when we

11:39 Speaker 1: finally hear that signal, we'll know that somewhere out there,

11:43 Speaker 1: other intelligent species figured out the same galactic hack we did.

11:48 Speaker 1: So keep your eyes, or rather your telescopes peeled. The

11:52 Speaker 1: next big discovery could just be a spin flip away.

12:43 Speaker 2: See you there, Astronomy Daily. We'll see and Haley Space Space,

12:50 Speaker 2: Science and Astronomy.

13:02 Speaker 3: The United States Space Force just offered a rare glimpse

13:04 Speaker 3: of its shadowy X thirty seven B spaceplane in orbit.

13:08 Speaker 3: The photo, released on Thursday, February twentieth, was taken by

13:12 Speaker 3: a camera on board the X thirty seven B while

13:14 Speaker 3: the secret of spaceplane orbited high above the African continent.

13:18 Speaker 3: One of the plane's solar panels is visible on the

13:21 Speaker 3: left side of the photo, while what appears to be

13:23 Speaker 3: its open payload bay is visible along the top edge.

13:26 Speaker 3: The vehicle has been in orbit for well over a

13:28 Speaker 3: year now, having launched on its seventh mission on December

13:31 Speaker 3: twenty eighth, twenty twenty three, atop a SpaceX Falcon heavy rocket,

13:36 Speaker 3: and now the X thirty seven B has notched another

13:38 Speaker 3: milestone with the Space Force's release of this photo, the

13:41 Speaker 3: first ever image of this spaceplane in orbit that has

13:43 Speaker 3: been shown to the public. While the photo contains scant

13:47 Speaker 3: details about the vehicle and what it's currently testing. It

13:49 Speaker 3: offers a look at Earth in the background, revealing just

13:52 Speaker 3: how high the vehicle is flying on its seventh mission.

13:55 Speaker 3: We've gotten only one other glimpse at the X thirty

13:58 Speaker 3: seven B in orbit prior to this. During the live

14:01 Speaker 3: stream of its most recent launch, a brief shot of

14:03 Speaker 3: the spacecraft deploying from Falcon heavy' upper stage was seen

14:06 Speaker 3: while its service module was still attached. When the X

14:10 Speaker 3: thirty seven B was preparing to launch on its current mission,

14:13 Speaker 3: the US Space Force revealed the flight would include operating

14:15 Speaker 3: the reusable spaceplane in new orbital regimes, experimenting with future

14:19 Speaker 3: space domain awareness technologies, and investigating the radiation effects on

14:23 Speaker 3: materials provided by NASA. According to a Space Force statement,

14:28 Speaker 3: previous X thirty seven B missions were flown in low

14:31 Speaker 3: Earth orbit, but as this photo reveals, the space plane

14:34 Speaker 3: is currently operating much farther from Earth. SpaceX's Falcon Heavy

14:38 Speaker 3: is capable of launching payloads into geosynchronous orbit over twenty

14:42 Speaker 3: two thousand miles thirty five thousand kilometers above our planet.

14:46 Speaker 3: The X thirty seven BE recently made headlines when Space

14:49 Speaker 3: Force and Boeing, who built the vehicle revealed that it

14:51 Speaker 3: would be testing a new aerobraking maneuver that uses the

14:54 Speaker 3: drag or friction generated by Earth's atmosphere to change orbit

14:58 Speaker 3: more efficiently.

15:00 Speaker 2: I mean to Astronomy Daily Fisteve Dunkel.

15:07 Speaker 1: Did you notice how Hallie managed to get my space

15:11 Speaker 1: force story. That's funny how she sneaks away with things

15:15 Speaker 1: like that. Meanwhile, astronomers have found a small, fast moving

15:21 Speaker 1: star racing through the center of our galaxy, possibly with

15:24 Speaker 1: a planet in orbit. If confirmed, this would be the

15:27 Speaker 1: fastest known sorry exo planet system, traveling nearly twice as

15:33 Speaker 1: fast as our Solar system through the Milky Way. You

15:36 Speaker 1: may be wondering how fast that actually is. Hey, I

15:39 Speaker 1: once got an Amazon delivery in less than twenty four hours,

15:42 Speaker 1: but that's just peanuts to how fast this star seems

15:45 Speaker 1: to be tearing across space. The system is estimated to

15:49 Speaker 1: be moving at an incredible speed. Now wait for this,

15:52 Speaker 1: of least one point two million miles per hour. That's

15:57 Speaker 1: five hundred and forty kilometers per second. Wow. We think

16:02 Speaker 1: this is a so called super neptune world orbiting a

16:06 Speaker 1: low mass star at a distance that would be live

16:10 Speaker 1: between the orbits of Venus and Earth. If it, we're

16:12 Speaker 1: in our Solar system, said Sean Terry, a postdoctoral researcher

16:17 Speaker 1: at the University of Maryland and NASA has got out

16:20 Speaker 1: space Flight Center in Greenbelt, Maryland. Since the star is

16:24 Speaker 1: so feeble, that's well outside its habitable zone. If so,

16:27 Speaker 1: it will be the first planet ever found orbiting a

16:30 Speaker 1: hypervelocity star. The findings, led by Terry were published in

16:34 Speaker 1: the Astronomical Journal on February ten. The pair of objects

16:38 Speaker 1: was first spotted indirectly in twenty eleven thanks to a

16:41 Speaker 1: chance alignment. A team of scientists comes through the archived

16:45 Speaker 1: data of MOA. That's the micro Lensing Observations in Astrophysics,

16:50 Speaker 1: a collaborative project focused on micro lensing survey conducted in

16:53 Speaker 1: the University of Canterbury Mount john Obs Observatory in New

16:58 Speaker 1: Zealand in search of life signals that betray the presence

17:02 Speaker 1: of exoplanets or planets outside our Solar System. Micro Lensing

17:06 Speaker 1: occurs when the presence of mass warps the fabric of

17:10 Speaker 1: space time. Anytime an intervening object appears to drift near

17:14 Speaker 1: a background, star light from the star curves as it

17:18 Speaker 1: travels through the space time around the nearer object. If

17:22 Speaker 1: the alignment is especially close, the warping around the object

17:25 Speaker 1: can act like a natural lens, amplifying the background stars light.

17:30 Speaker 1: In this case, micro lensing signals reveal a pair of

17:33 Speaker 1: celestial bodies. Scientists determine their relative masses. One is about

17:38 Speaker 1: twenty three hundred times heavier than the other, but their

17:41 Speaker 1: exact masses depend on how far away they are from

17:43 Speaker 1: the Earth. It's sort of like how the magnification changes

17:47 Speaker 1: if you hold a magnifying glass over a page and

17:49 Speaker 1: move it up and down. Determining the mass ratio is easy,

17:54 Speaker 1: said David Bennett, a research scientists at the University of

17:58 Speaker 1: Maryland College Park and A Godard, who co authored the

18:02 Speaker 1: paper and led the original study in twenty eleven. It's

18:06 Speaker 1: much more difficult, he said, to calculate their actual masses.

18:10 Speaker 1: The twenty eleven discovery team suspected the microlens object where

18:14 Speaker 1: ei they're a star about twenty percent as massive as

18:18 Speaker 1: our Sun and a planet roughly twenty nine times heavy

18:21 Speaker 1: than the Earth, or near a rogue planet about four

18:25 Speaker 1: times of Jupiter's mass with a moon smaller than Earth.

18:29 Speaker 1: To figure out which explanation is more likely, astronomers searched

18:33 Speaker 1: through data from Keck Observatory in Hawaii and the European

18:36 Speaker 1: Space Agency's gay A satellite. If the pair were a

18:39 Speaker 1: rogue planet and moon, they'd be effectively invisible. Dark objects

18:43 Speaker 1: get lost in the inky void of space, but scientists

18:46 Speaker 1: might be able to identify the star if the alternative

18:49 Speaker 1: explanation were correct, though the orbiting planet would be much

18:53 Speaker 1: too faint to actually see. They found a strong suspect

18:57 Speaker 1: located about twenty four thousand light years way, putting it

19:00 Speaker 1: within the Milky Ways galactic bulge the central hub where

19:04 Speaker 1: the stars are more densely packed. By comparing the stars

19:08 Speaker 1: location in twenty eleven and twenty twenty one, the team

19:11 Speaker 1: calculated its high speed, but that's just its two D emotion.

19:15 Speaker 1: If it's also moving toward or away from us, it

19:18 Speaker 1: must be moving even faster. Its true speed may be

19:22 Speaker 1: high enough to exceed the galaxy's escape velocity of just

19:26 Speaker 1: over one point three miles per hour or about six

19:29 Speaker 1: hundred kilometers per second. If so, the planetary system is

19:34 Speaker 1: destined to traverse the intergalactic space many millions of years

19:38 Speaker 1: into the future. To be certain a new identified star

19:42 Speaker 1: is part of the system that caused the twenty eleven signal.

19:45 Speaker 1: We'd like to look again in another year and see

19:48 Speaker 1: if it moves the right amount in the right direction

19:51 Speaker 1: to confirm it it came from the point where we

19:54 Speaker 1: detected the signal. Then it said. If a high resolution

19:58 Speaker 1: observation show that the star just stays in the same position,

20:01 Speaker 1: then we can tell for sure that it's not part

20:03 Speaker 1: of the system that caused that signal, said a Panabatacha,

20:06 Speaker 1: a research scientist at University of Maryland College Park and

20:10 Speaker 1: NASA Goddard who co authored the new paper. That would

20:13 Speaker 1: mean the Roague planet and exomoon model is favored. NASA's

20:18 Speaker 1: upcoming Nancy Grace Roman Space Telescope will help us find

20:22 Speaker 1: out how common planets are around such speedy stars and

20:25 Speaker 1: may offer clues as to how these systems are accelerated.

20:29 Speaker 1: A mission will conduct survey of the galactic bulge, pairing

20:33 Speaker 1: a large views of space with crisp resolution. In this case,

20:37 Speaker 1: we used MOA for its broad field view and then

20:41 Speaker 1: followed up with KEK and GAIA for their sharper resolution.

20:45 Speaker 1: But thanks to Roman's powerful view and planned survey strategy,

20:49 Speaker 1: we won't need to rely on additional telescopes, Terry said,

20:53 Speaker 1: Roman will do it all. Isn't it exciting to see

20:56 Speaker 1: that our view of the skies is becoming clearer and

20:58 Speaker 1: clearer with each new development. It's space telescope technology.
