New Hubble images of Comet 3I Atlas.	speaker_0	neutral	en
And in Space Bites plus, staring right down the jet of an actively feeding supermassive black hole.	speaker_0	neutral	en
All this and more, in this week's Space Bites.	speaker_0	happy	en
[digital screen click] All right, this is it, this is the moment we've all been waiting for.	speaker_0	angry	en
Uh, Webb has been looking at the planets, one by one, in the TRAPPIST-1 system.	speaker_0	angry	en
And finally, when Webb arrived, it was the right machine, capable of being able to observe atmospheres on exoplanets.	speaker_0	angry	en
What do we find?	speaker_0	angry	en
And so far, nothing.	speaker_0	angry	en
So the closest two planets to the TRAPPIST-1 star, these are TRAPPIST-1b and TRAPPIST-1c.	speaker_0	angry	en
And it was always assumed that this was a very long-shot chance to be able to detect anything, but the hope was that you would get something like a Venus, where you've got these Earth-sized worlds orbiting close to the star, they're superheated, thick atmospheres of carbon dioxide.	speaker_0	angry	en
But they pretty conclusively have been found to have no atmosphere.	speaker_0	angry	en
And that's not very surprising because TRAPPIST-1 is a super flare star, which means that it generates a tremendous amount of flare activity that would scour the atmospheres off of any planets that are too close.	speaker_0	angry	en
Now, the first planet that is just barely within the habitable zone is TRAPPIST-1d.	speaker_0	angry	en
We've been anticipating this day for a very long time, and the results are no atmosphere detected.	speaker_0	angry	en
Now, this doesn't mean there's no atmosphere.	speaker_0	angry	en
It just means that there was no atmosphere detected, and there's a couple of possibilities that could explain that.	speaker_0	angry	en
It's just not enough atmosphere to be able to make this detection.	speaker_0	happy	en
But the other possibility is that it's actually a very thick atmosphere, like Venus, but just such a thick layer of clouds at the top that it's obscuring any of the elements underneath.	speaker_0	angry	en
And we didn't get any detection of carbon dioxide or methane or water vapor in the atmosphere.	speaker_0	angry	en
It's at best inconclusive, and at worst, there's just no atmosphere there at all.	speaker_0	angry	en
But it's still early days and astronomers are still developing their techniques on how to be able to make these kinds of observations.	speaker_0	neutral	en
And I had a fantastic interview with Megan Giacaluca earlier this year, where she went through each of the planets in order and gave us sort of a sneak peek of what we might expect with TRAPPIST-1d.	speaker_0	angry	en
Stay tuned.	speaker_0	angry	en
But if you want more information, we've got a story about this by Evan Goff.	speaker_0	angry	en
[Digital screen click] Now, speaking of TRAPPIST-1, we've got more information about the star itself, and this is probably the biggest challenge that astronomers are dealing with, is that because TRAPPIST-1 is a flare star, in other words, it puts out a lot of very powerful flares, very active, it's really difficult to distinguish what is the signal of the light that's coming from the planets around	speaker_0	angry	en
Once you get a sense of just how active the star is, then you can set that as a baseline to then tease out the atmospheric information of the planets in orbit around it.	speaker_0	angry	en
And we know that the star is covered by various magnetic features.	speaker_0	angry	en
You've got sunspots, you've got faculae, you've got w- areas of convection and that magnetic fields that are twisting and turning, and this is all contributing to the changes in brightness of the star.	speaker_0	happy	en
When are we seeing a flare or some kind of magnetic event on the surface of the star?	speaker_0	angry	en
[static] All right, let's move on to Comet 3I Atlas, which is the third interstellar object to pass through the solar system.	speaker_0	angry	en
And unlike the previous two, 'Oumuamua and Borisov, 3I Atlas, we are seeing it inbound into the inner solar system, but it is moving faster than any interstellar object that we've seen so far today.	speaker_0	neutral	en
And its coma, the ball of gas and dust around the central nucleus, and the tail are starting to form.	speaker_0	happy	en
And normally a comet within the solar system, say from the Oort cloud, is only giving off between 3 and 5% of its surface is giving away water when it's this distance away from the sun.	speaker_0	neutral	en
And so you have less heavier elements.	speaker_0	angry	en
This is gonna be really interesting as the comet gets closer, as it reaches higher amounts of sublimation from the radiation coming from the sun, and then astronomers are gonna be able to watch it through this entire process once it crosses that closest point and starts to move away from the sun again.	speaker_0	neutral	en
How quickly will that tail die down?	speaker_0	angry	en
You'll get even more information about the star system that the comet came from.	speaker_0	neutral	en
One other thing is that normally at this point when you see a comet, you see cyanogen gas coming off a comet.	speaker_0	neutral	en
But normally at this point, you see cyanogen gas coming off of the comet, and yet so far, we don't see any of that gas.	speaker_0	neutral	en
We've got a longer story about that by Andy Thomas Wick.	speaker_0	neutral	en
[static] And, of course, the Hubble Space Telescope has joined in the fun and taken its first images of Comet 3I Atlas.	speaker_0	angry	en
So here is your picture of 3I Atlas taken by Hubble, and this picture was taken at 3.	speaker_0	angry	en
All of this gas and dust is starting to surround the central nucleus of the comet.	speaker_0	neutral	en
And of course, as we said, a lot of this, a surprising amount of this, is water, and you're starting to see that tail start to form, and this is just getting bigger and bigger and bigger.	speaker_0	happy	en
As it gets closer to the sun, there's more radiation pressure, it's starting to push away this material.	speaker_0	angry	en
You're gonna see that big, wonderful tail from an interstellar object.	speaker_0	angry	en
So thanks to Hubble, we're learning a ton more about this.	speaker_0	angry	en
And again, like we're still, you know, it's not gonna get to its closest point until October.	speaker_0	angry	en
We've got lots more time to study this object as it gets closer and closer and then gets farther and farther.	speaker_0	neutral	en
[static] All right, let's go back to talking about little red dots.	speaker_0	angry	en
What do we know about them?	speaker_0	angry	en
They are bright and they are early.	speaker_0	angry	en
They're within the first billion years after the Big Bang, and they're putting out a surprising amount of radiation in a very tight place.	speaker_0	angry	en
And so how do you get that much radiation from such a small grouping?	speaker_0	angry	en
Like they probably have about one tenth the size of a galaxy like the Milky Way.	speaker_0	neutral	en
One possibility is that you've got a supermassive black hole that is starting to feed and is putting out large amounts of radiation.	speaker_0	neutral	en
The other possibility is that you've just got a very compact galaxy where you've got lots of stars in a small area.	speaker_0	angry	en
But as we talked about last week, if it is a supermassive black hole, not only would you expect to see large amounts of the radiation seen by Webb, but you would detect the radiation with other telescopes in other wavelengths, like in x-rays, and we don't see that.	speaker_0	neutral	en
And so if these things are rotating very quickly, which is what is more common, then you get this centripetal outward force that causes the galaxy and the stars to get more distributed.	speaker_0	neutral	en
And so that might help explain why you can get all those stars that much closer together.	speaker_0	neutral	en
You know, the, the quest to understand these little red dots goes on, and we still have decades left to try and figure this out before we lose Webb.	speaker_0	happy	en
And we've got a story on this from Mark Thompson.	speaker_0	neutral	en
Just for comparison, the supermassive black hole at the heart of the Milky Way, Sgr A*, contains 4.	speaker_0	neutral	en
There's probably 100 million solar mass black hole at the heart of Andromeda, and astronomers have found ones that have billions of times the mass of the sun.	speaker_0	angry	en
And now they think they found the most massive, one with $36-Billion times the mass of the sun.	speaker_0	angry	en
And the gravity around the cosmic horseshoe is so strong that it has a beautiful Einstein lens surrounding it, where you've got almost this perfect circle of gravitational lensing around this galaxy.	speaker_0	happy	en
Astronomers have used several methods to try to measure the mass of the black hole at the heart of this galaxy.	speaker_0	neutral	en
And so one method is that they measure the pathways that the light is taking, that as it gets closer to the center of the galaxy, it's pulled by the super massive black hole, and that allows you to measure how much mass is pulling on that light.	speaker_0	happy	en
The other method is to be able to actually measure the movements of the stars at the center of the galaxy.	speaker_0	angry	en
And they're going very fast.	speaker_0	angry	en
In fact, this is how they discovered the super massive black hole at the heart of the Milky Way.	speaker_0	angry	en
They did the same thing with the cosmic horseshoe and measured the stars moving 400 kilometers per second around nothing.	speaker_0	angry	en
I'm sure this record will be broken again, but still, uh, very interesting.	speaker_0	angry	en
And you can learn more about the method they used to figure this out by reading the story from Evan Gough.	speaker_0	angry	en
[tape scratching] When our sun dies, it will become a white dwarf star.	speaker_0	angry	en
And that accounts for about 50% the mass of the sun.	speaker_0	angry	en
And if a white dwarf eventually feeds off some partner star and gets up to 1.	speaker_0	angry	en
So how did it get that massive?	speaker_0	angry	en
Well, one possibility is that it fed off some partner star and isn't doing that anymore.	speaker_0	neutral	en
But the other possibility is that it merged with another white dwarf star, and some really valuable clues there.	speaker_0	neutral	en
When astronomers observed this white dwarf, they detected the presence of carbon in the atmosphere of the star.	speaker_0	neutral	en
But not only do you see carbon, you see other heavier elements, like silicon or neon.	speaker_0	angry	en
But in this case, they didn't find those heavier elements.	speaker_0	neutral	en
And so it appears that you got two white dwarfs that merged to become a 1.	speaker_0	neutral	en
[tape scratching] Every week we do a vote on our channel where you tell us what you thought was the best space news story of the week, and the winner this week was, what?	speaker_0	angry	en
What a surprise.	speaker_0	angry	en
[children cheering] Planet found at Alpha Centauri.	speaker_0	neutral	en
[mouse clicking] Click on the notifications bell [bell ringing] and then train the algorithm.	speaker_0	angry	en
[tape scratching] On to Mars.	speaker_0	angry	en
One of the big challenges in driving a rover round on Mars is the regolith, and we learned this when NASA's Spirit Rover got stuck in the sand as it was trying to go across an area on Mars.	speaker_0	angry	en
Its wheels got stuck, it wasn't able to point its solar panels towards the sun, and then it wasn't able to keep itself warm during the night on Mars, and it died.	speaker_0	neutral	en
So don't get caught in the sand is like rule number one for Mars rover drivers.	speaker_0	angry	en
Does that look like sand?	speaker_0	angry	en
Let's avoid it.	speaker_0	angry	en
Try to stay on the rock.	speaker_0	angry	en
You can reduce the weight of your rover.	speaker_0	angry	en
You know, you tie ropes to it and then it appears like it's one third the normal weight is what it would feel like when it's on Mars.	speaker_0	neutral	en
But you can't change the weight of the individual particles of the sand, and the sand changes differently when it's in a lower gravity environment.	speaker_0	angry	en
And so researchers are now trying to split the difference.	speaker_0	angry	en
They've developed a really cool simulation on computer where they simulate the effect of a rover going on sand.	speaker_0	angry	en
