Hello and welcome to this episode of Night Sky News for September 2024! This is the show where we chat about what you should look out for in the night sky in the next month, and what’s been happening in space news in the past month. In this episode we’re chatting about SO many things, including which planets you can spot in the night sky, the annular solar eclipse visible across South American, how to look out for C/2023 A3 (Tsuchinshan–ATLAS) if it becomes bright enough as it gets closer to the Sun, plus the successful lunar-earth flyby of the JUICE spacecraft on its way to Jupiter, the new hypothesis to explain the famous unexplained Wow! signal (which sadly isn’t aliens), and a new explanation for JWST’s “impossible” over-massive galaxies!

👩🏽💻 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.
