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

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 ...

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 ...

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

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

The idea of relative motion is an aspect of the theory of relativity (strictly, it’s Galilean relativity, rather than ...
