Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...

A string of small gas clouds near the Milky Way’s central black hole has puzzled astronomers for years. Now, new observations suggest those clouds are not random scraps drifting through space. They ...

Since the third Gaia data release in 2022, wide binary stars with separation greater than several thousand astronomical units have been intensely investigated across the world, to probe the nature of ...

In theory, it could happen – one of the very first solutions to the three-body problem was this scenario. But it is very unlikely to be stable over time. You need the stars to have near equal mass and ...

The supermassive black hole at the center of our Milky Way galaxy is associated with wanton destruction, but a recent discovery throws that assumption into question. A team of international ...

Astronomers have confirmed a giant planet orbiting a tightly bound pair of young stars, marking a first in direct exoplanet imaging. The planet, known as HD 143811 AB b, is the closest-in world ever ...

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 ...

University of Warwick astronomers have discovered an extremely rare, high-mass, compact binary star system only ~150 light years away. These two stars are on a collision course to explode as a type 1a ...
