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

Pulsars are a special class of neutron stars that spin very quickly on their axes, releasing pulses of radio waves. These ...

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 ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

Researchers believe they have found the signal of a pulsar, the ancient core of a rapidly spinning star, at the center of the Milky Way, near a supermassive black hole. This discov ...

Ripples in space-time from a pair of merging black holes have been recorded in unprecedented detail, enabling physicists to test predictions of general relativity ...

Albert Einstein won the 1921 Nobel Prize in Physics, but not for relativity—the theory that made him famous. This article unpacks why the Nobel committee hesitated: Alfred Nobel’s rules, distrust of ...
