In this month's Night Sky News episode we're chatting about the Amaterasu cosmic ray particle that hit the Earth with 813 billion times more energy than a typical cosmic ray particle! Plus there's three new exoplanet research articles released this past month from the first planet forming system spotted outside the Milky Way in the Large Magellanic Cloud, to a "perfect" 6 planet system all in resonance with each other, and a new paper claiming we sadly don't have any evidence for exomoons. And of course there's all the details on how you can spot the Quadrantids meteor shower in January, and the International Space Station in December.

👩🏽‍💻 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.
