Astronomers have identified a tightly bound pair of stars that are spiraling toward a catastrophic merger, turning a distant stellar system into a natural laboratory for testing gravity at its most ...

What can binary stars comprised of two different types of stars teach astronomers about stellar evolution? This is what a recent study published in The Astrophysical Journal hopes to address as a team ...

Every galaxy has a supermassive black hole at its center, much like every egg has a yolk. But sometimes, hens lay eggs with two yolks. In a similar way, astrophysicists like us who study supermassive ...

A team of astronomers have found a pair of supermassive black holes near the center of a newly forming galaxy. The black holes were found hiding in the center of the galaxy merger known as UGC 4211.

A binary pair of red stars -- one giant, one dwarf -- has been discovered by a collaboration of astrophysicists from the UK and China. A binary pair of red stars, one giant one dwarf, has been ...

Some black holes, bound by gravity, rotate around each other, as shown in this simulated image. Simulating eXtreme Spacetimes Lensing (SXS), CC BY-SA Black holes are regions of space where gravity is ...
