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 ...

Stars usually form in clusters, which can also form in pairs or groups. Binary clusters (BCs) are defined as pairs of open ...

Apples-to-apples comparisons in the distant universe are hard to come by. Whether the subject is dwarf galaxies, supermassive black holes, or “hot Jupiters,” astronomers can spend months or years ...

A research team has used both archival Hubble Space Telescope data and new observations to precisely measure the binary star system NGC3603-A1. One star weighs about 93 times the mass of our sun, ...

A nearby binary star system is bereft of giant planets, but scientists think it may still be a decent place to look for life.

Ultimately, this could reveal how stars smaller than Jupiter are born. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Astronomers have ...

For the first time, astronomers have spotted a rapidly spinning neutron star that is gravitationally bound to a helium star companion. The discovery of this unusual binary system helps confirm a long ...

Astronomers have detected a binary star system orbiting Sagittarius A*, the Milky Way's central supermassive black hole. Credit: ESO / S. Guisard Just on the outskirts of a supermassive black hole ...

An international team of researchers has detected a binary star orbiting close to Sagittarius A*, the supermassive black hole at the centre of our galaxy. It is the first time a stellar pair has been ...
