- The star Fomalhaut seems to have three asteroid belts, based on new James Webb Space Telescope observations. Drs. András Gáspár, George Rieke, and Schuyler Wolff tell us why!
00:00 Introduction
02:06 Interview begins
03:40 Hunting for exo-asteroids at Vega and Epsilon Eridani
04:30 What are "Thermal Locations" in a planetary system?
06:29 Why is there a debris disk?
09:02 Are the rings caused by planets?
09:41 Why weren't these rings seen by Hubble or ALMA?
10:58 What happened to the "exoplanet" Fomalhaut b?
12:26 Why don't we see planets with Webb/MIRI?
13:09 How were the images made with MIRI?
14:23 Unreleased composite images of Fomalhaut!
15:00 Will Fomalhaut be around long enough to have a solar system like ours?
15:32 Bloopers

Crazy that 30 years ago we didn't know that the Kuiper belt was even real but now we can detect alien Kuiper belts.
That’s a pretty cool thing!
@@LaunchPadAstronomyit's cool you have all these friends that are actually working on this stuff
yooo, good editing!! awesome video! it was not boring and easy to follow/understand! 😸
Thank you! I've found that editing interviews to be a lot tricker than I thought they would be. Figuring out what to show to support what they're saying is a dark art :)
I love when you have these interesting guests on your show breaking down all of the new information from JWST as well as other telescopes ! It’s the perfect way to start your day. 👍🏻🔭
I'm really excited for the Vega and E Eri observations.
I find it facinating that one of the key features in a novel published in 1981 (The Pride of Chanur by C.J. Cherryh) was a solar system exactly like this. She likened it to a 'fried egg' and spent a great deal of time describing what travel through this system would be like
Yes, yes, yes, Fomalhaut has a planet again!! Until now, I still was mourning planet "Dagon", which turned out to be a dust cloud.
Another fantastic video!
Thanks man!
We are so fortunate to be living in theses times, so many new technological discoveries. Think what’s yet to come, amazing.
This is exactly the video that I wanted to watch!!
Great! I'm glad you enjoyed it :)
Oh how fantastic to see this video. I took Dr. Riecke's Astronomy 101 at the UofA.... a bit ago lol.
Cool! I would have liked to have been his student, he seems like a great guy!
So cool to hear from the authors of the paper thank you!
Thank you for making these videos!
Thank you for the share!
Never gets old watching these informative videos!
Thanks!
looks like sunshine daydream...... Thanks Christian, every one of your videos is fascinating and informative, keep 'em coming for as long as you can man!
As long as I can keep the days between videos as short as possible.
You just got yourself a new subscriber! Just saw your Beetlejuice video and wow was I impressed with how you explained and documented and put that video together anything space science especially to do with this stuff I'm all over it thank you for making these videos I cannot wait watch the rest of them seriously Round of Applause for you 👏👏👏👏💜
Wow thank you, and I'm glad to have you along for the ride!
@@LaunchPadAstronomy you are very welcome. like seriously the way you approach things so calmly and go about presenting these videos is really refreshing, wherever you might be Greece from Southern California!(:
It really hammers home just how vulnerable we are here.
Fomalhaut is Arabic for "Mouth of the Fish" and is the mouth part of the constellation of the Southern Fish (Piscis Austrinus) Since there are fishes with several layers of teeth/fangs, I wonder if these asteroid belts coincidentally represent the layer of fangs of the fish constellation
That's a pretty cool thought!
Oooh! The fish is actually a shark then. Nice.
well ancient astronomers didn't know about the asteroid belts so no but from a modern perspective its a call observation even though its not the only star with asteroid belts
Literally فم الحوت, “mouth of the whale.” حوت generally meant “whale;” in the modern literary language the baleen whale, specifically. Ancient Arabic-speaking peoples weren't very much into fishing, considering the geography, and there had been relatively few words for different kinds of sea creatures. And no, of course they didn't see the ring.
"Rings of Fomalhaut" sounds like a great name for a scifi epic. I really want to read it now.
thanks for the video
My pleasure!
Thank you Christian. Thats awesome
Appreciate it!
It's very impressive.
What is a temperature of disks' material? What about theirs density and chemical composition? Does distribution of temperature correspond with any good model?
Good point: we see objects with size >= wave length. It's pretty obvious, but it's worth remembering.
0:19 SOFIA has both entered and left the chat.
So, Sauron´s eye has a ring under it, he must be tired 🙂
Visually it looks like there are peaks and troughs in the dust. So the light emitting from the sun is being block, similar to a shadow being casted by a whirlpool in a water body.
Hey there, could you do a video of the early galaxies that were discovered, that are too close to the "big bang" and what your thoughts are? Maybe you could even talk with someone about it. That would be an interesting video to watch
Thanks for the suggestion!
I don't know if I'm actually recording you. You may come to regret this
🎉🎉🎉
Is there a chance the intermediate ring is just an optical artifact?
So 😎 if that doesn't get people into astronomy nothing well
If Fomalhaut is a star, then why is its shape so odd? Rocky looking with what I'll call Tabs on top and bottom with the top one much taller? Don't stars usually appear to be a globe?
سبحان الله و بحمده سبحان الله العظيم
These rings are planets in formation. There's probably more.
🖖👽
What I'm curious about (both from this and earlier observations) is why the star appears to be well off-center from the disks.
Images that NASA didnt released? I wonder how many more that they didnt release? An the purpose behind those actions
All of the images are freely available to the public on the MAST archive. However, processing those images for public release requires a fair amount of time and effort. Fortunately, the science team did their own image processing on the data which we discussed in the video.
NASA is obligated to release to the public. Everything they do is public. However, do you know how to process imagery in wavelengths other than visual? Probably not. Those who do aren't going to make every single piece of data that comes through into something you can understand. Learn about wavelengths and GIS before you say they aren't releasing photos. They aren't even photos. Just pieces of information the general public can't even comprehend.
To clarify. Every piece of data that comes from a NASA satellite is available. You just need to be smart to translate it, and they don't translate their garbage data.
Sorry Scott Manley...
Alot of us want Webb to be looking for Life. Not Rocks. Lets Go !

Thumb down for spelling Fomalhaut wrong in the thumbnail. Names matter, more than most other words. And it's trivial to check this online.
Awesome, great catch. Thanks!
@@LaunchPadAstronomy Wow, that's unusually gracious. Enough so that I flipped it to a like. I don't know when I've ever done that.
@@ronaldgarrison8478
The man has class. According to your comment, something you don’t have or understand.
@@AttilaTheHun333333 I see you don't like my attitude, but I don't see you telling me I'm wrong. Take a moment to notice, and you may see that the owner of the channel handled this much better than you have.
Cool images. Far too much blatant conjecture about how the rings form stated basically as fact. There's clearly a lot we haven't seen and don't understand about stars and solar system formations. No one is just willing to say "we don't know". More scientists need to stick with science and make it clear when they are saying things that are guesses and not facts.
