This Night Sky News we're chatting about what JWST results we've been treated to this week, including a beautiful spectrum of one of the most distant galaxies known, GN-z11. Plus there's been a claim of observational evidence of SMBH growth that can't be accounted for which some researchers have claimed is evidence that black holes are responsible for the accelerated expansion of the Universe (i.e. dark energy). This one hurt my head to film, so let's dive in to understand it together.

👩🏽💻 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.
