Astronomy News Today
In this month's Night Sky News we chat about how to spot the Moon occulting Mars, the beginnings of the Artemis 1 mission, the latest JWST updates including its new plan to avoid micrometeorites, and a new study on the Winchcombe meteorite that confirms ideas that water was brought to Earth by asteroid impacts.

👩🏽💻 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.
