"We studied the last several orbits before the merger, when the entwined magnetic fields undergo rapid and dramatic changes, ...

A mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...

The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, ...

Merger of two neutron stars in the aftermath of a supernova may have been observed for the first time, though questions ...

Add Yahoo as a preferred source to see more of our stories on Google. This artist's concepts shows a hypothesized event known as a superkilonova. A massive star explodes in a supernova (left), which ...

More than 4,000 astronomers on Monday revealed the first-ever detection of two neutron stars colliding in space. Such objects are the skeletons of massive stars that have cataclysmically exploded, ...

Gravitational waves are ripples in spacetime predicted by Einstein and first detected by LIGO in 2015, confirming black hole ...

Neutron stars escape collapse into a black hole thanks to degeneracy pressure produced by their neutrons, which is able to fight the crushing force of gravity. What exactly lies at the heart of a ...
