New study claims Betelgeuse supernova IMMINENT (decades not centuries!) | Night Sky News June 2023

In this month's Night Sky News we're chatting about a new study claiming Betelgeuse will be going supernova in the next few DECADES, JWST’s discovery of water on a rare type of comet, JWST’s study of the plumes of water from Saturn’s moon Enceladus, and much more.

👩🏽‍💻 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.
