See a pair of superheavy neutron stars collide in this simulation with gravitational wave audio. "An audible tone and a ...

Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two ...

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 ...

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 ...

XRISM’s observations of GX13+1 revealed a slow, fog-like wind instead of the expected high-speed blast, challenging existing models of radiation-driven outflows. The discovery hints that temperature ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of millions of years, these stars progressively cool down, radiating heat into ...

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 ...
