Dr. Becky | JWST has taken the most DETAILED spectrum of an exoplanet EVER @DrBecky | Uploaded 1 year ago | Updated 3 days ago
JWST has taken a DIRECT spectrum of an exoplanet mass object (it could be a failed star, the jury is still out on that one) and it is the most detailed, beautiful spectrum you ever did see. It's revealed the existence of silicates (think sand) in the atmosphere and suggests it has very dusty clouds and storms. It's also orbiting around TWO stars, so there's been a lot of comparisons to Tatooine from Star Wars! #jwst #astronomy #astrophysics

👩🏽💻 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.
