In new research, found that there was a good correlation between the flicker of a star and its surface gravity.
Astronomers have found a stormy dark spot on a small star.

Astronomers have developed a new method using “twin stars” to measure stellar distances.
Suppose you wanted to build a star. How would you go about making one?
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.
