Crazy that 30 years ago we didn't know that the Kuiper belt was even real but now we can detect alien Kuiper belts.

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

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

@LaunchPadAstronomy Год назад

That's a pretty cool thought!

@dogcarman Год назад

Oooh! The fish is actually a shark then. Nice.

@EvaFuji Год назад

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

@cykkm Год назад

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.

@VikingTeddy Год назад

"Rings of Fomalhaut" sounds like a great name for a scifi epic. I really want to read it now.

@kagannasuhbeyoglu Год назад

@macdtravis Год назад

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.

@Mr.Snow12 Год назад

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

@LaunchPadAstronomy Год назад

Thanks for the suggestion!

@cavesalamander6308 Год назад

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.

Is there a chance the intermediate ring is just an optical artifact?

@100vg Год назад

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?

These rings are planets in formation. There's probably more.

@ariochiv Год назад

What I'm curious about (both from this and earlier observations) is why the star appears to be well off-center from the disks.

@bee7244 Год назад

Images that NASA didnt released? I wonder how many more that they didnt release? An the purpose behind those actions

@LaunchPadAstronomy Год назад

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.

@Tom-vx5eq 6 месяцев назад

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.

@Tom-vx5eq 6 месяцев назад

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.

@PreppenWolfLLC Год назад

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.
