Astronomers have weighed a neutron star with nearly double the mass of the sun, the heaviest yet found. A mass that high rules out many theories that these ultradense remnants of supernova explosions ...

A: The quick answer to your question is yes, they can gain matter. However, only a small fraction of neutron stars can gain mass — those in binary systems, where mass is transferred from the companion ...

Massive merger: illustration of gravitational waves from a neutron-star merger Data from the recent observation of gravitational waves from the merger of a binary neutron star have been used to place ...

A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent encounters. Scientists have found the first strong evidence that a black hole and a ...

The first observation of neutron stars colliding happened in August 2017 and was notable for showing that both gravitational waves and light were generated by the event. The more recent observation of ...

Astronomers at the Green Bank Observatory in West Virginia have located the most massive neutron star on record, so dense that it may be close to the cusp of collapsing into a black hole. Neutron ...

On Aug. 17, gravity waves rippled through the solar system, slightly squeezing and stretching the space Earth occupies, the result of a catastrophic collision of two compact-but-massive neutron stars, ...

A new study showing how the explosion of a stripped massive star in a supernova can lead to the formation of a heavy neutron star or a light black hole resolves one of the most challenging puzzles to ...
