The new James Webb Space Telescope images of the Cartwheel Galaxy are STUNNING. But is that the colour we’d really see? What science can we learn from these images? And what are those objects that have moved since the Hubble Space Telescope took a look in 1995?

All raw JWST data that has been made public is accessed via MAST:

👩🏽‍💻 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.
