In this episode of Night Sky News we’re chatting about the latest results from the AAS243 meeting including the Big Ring megastructure of galaxies, the most distant fast radio burst, and of course the latest from JWST on the "Crisis in Cosmology" (aka the Hubble Tension) which has ruled out the most likely culprit that we all had our money on. Is it time for some new physics?

👩🏽‍💻 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.
