Astronomers have found a neutron star that spins 716 times per second. This changes things for astronomers. What they thought ...

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

By developing a new theoretical relation describing just how compact neutron stars — which are the remnants of massive stars that have gone supernova — can get, researchers have found a way to test ...

Astronomers have detected a mysterious cosmic 'heartbeat' repeating every 22 minutes, unlike any known celestial object.

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 ...

Scientists now believe highly magnetised neutron stars, or magnetars, are a significant source of gold and other heavy ...

NASA reveals that a particle wind powers pulsar J1023, aligning optical and X-ray polarization, which calls existing models ...

NASA's NICER telescope halts its mission after a key motor fails; engineers attempt to salvage eight years of space science.

The supernova was the death of a red supergiant star 500 times larger than the sun, in a galaxy just 22 million light-years ...

The explosive death of a star - a supernova - is among the most violent cosmic events, but precisely how this cataclysm looks ...
