The Milky Way’s disc is made up of two components — but where did they come from?
Ever wondered how astronomers study the structure of our own Galaxy from within? Read on to find out how the Gaia mission helps us in this regard!
Major galaxy mergers are thought to be one of the main ways of producing massive elliptical galaxies. Surprisingly though, some of the most massive galaxies in the local universe have gas disks. Here’s how they might be made.
Sorting the Sombrero galaxy into a galaxy classification is difficult to do, but new evidence suggests that like Harry Potter, the Sombrero galaxy may fit into more than one category.
A study of star clusters in the Milky Way has uncovered a peculiar trend in the way they are arranged.
