New research suggests Einstein's general relativity explains the rarity of planets orbiting two suns. In tight binary systems ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity ...

At the center of the Milky Way, close to the pull of a supermassive black hole, astronomers have found a strange new radio signal that behaves like a slow, steady clock. This object is more than an ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

Scientists hope to probe the nature of general relativity through a possible pulsar found in the center of the Milky Way, ...
