And welcome to this episode of Night Sky News for October 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 ExoMars’ view of interstellar comet 3I ATLAS, JWST’s spotting a supernova before it went supernova, and the latest on the crisis in cosmology, with a new independent measurement of the expansion rate of the Universe… Please note that the intro and outro of this video were recorded before I recently started a course of chemotherapy. The rest of the video was recorded as voiceover only.

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. http://drbecky.uk.com
