AD | Huge thanks to KiwiCo for sponsoring today’s video. Go to kiwico.com/astrodrbecky and use code ASTRODRBECKY for 50% off your first monthly crate! | Hello and welcome to this episode of Night Sky News for May 2025 with me, astrophysicist Dr Becky Smethurst. 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 the proposed cuts to the NASA budget which almost halve the space science programs budget, and its potential impact on astrophysics research, the latest on the construction of the extremely large telescope in Chile, and whether we’ve finally spotted the infamous planet nine at the edge of the solar system…

👩🏽💻 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.
