Why do young stars contain so much lithium? That might seem an odd question, but it’s a question that has nagged astronomers for quite some time.
Astronomers can measure the distance to about a billion stars using the same effect that lets you enjoy a 3D summer blockbuster.
The stars in our galaxy can change orbits over time. Through “close encounters” with other stars, they can find themselves in very different regions of the galaxy than their region of origin. Now new research finds that about a third of stars drift to new orbits in their lifetime.
Brown dwarfs are like the Pluto of stars. New research published in Nature points to a more planetary nature by discovering bright aurora on a brown dwarf.
Giant stars lurk the heart of the Westerlund 1 cluster.
A region of material similar to the Kuiper belt of our solar system has been directly observed around another star.
A Wolf-Rayet star nicknamed “Nasty 1” is having its hydrogen stolen by a companion star.

Caffau’s star is sometimes called an “impossible star.” It’s actually just an interesting star that we don’t fully understand.
