Space Mog | Mystery Scar on Dead Star hints at our Sun's grim future @SpaceMog | Uploaded 6 months ago | Updated 3 hours ago
Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! Astronomers have just discovered a bizarre "scar" on a dead star that changes shape as it rotates. This discovery could rewrite our understanding of white dwarfs and even the future of our own Sun!
