00:43 - What did JWST observe?
02:43 - Your FAQ from Instagram
03:42 - 1) How did JWST know where to look?
05:44 - 2) Why did only the rings block light from the star?
07:11 - 3) How do we know its rings and not something else?
08:42 - 4) How normal is it for asteroids to have RINGS?
11:09 - 5) What can we learn from these JWST observations? Where did water on Earth come from?

👩🏽💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.
