Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! Question in from John Lewis to talk about fossil galaxies, so in this week's video, I'll be talking about the fossil galaxy at the centre of our Milky Way and why it's not really a fossil!
