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 ...

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars' surface gravities are so intense that the largest "mountains" are only a few ...

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 ...

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

They are smaller than a city yet heavier than the Sun. Neutron stars crush matter, twist space-time, and spin faster than ...

Creating a neutron star Before you can get this ideal cosmic laboratory, a star first has to die. The end of a star’s life depends largely on its mass. Unremarkable stars like the Sun go out with a ...

Gravity from mountains on rapidly rotating neutron stars produces ripples in space-time known as gravitational waves. The Laser Interferometer Gravitational Wave Observatory (LIGO) searches for such ...

It weighs more than 2 times the mass of our sun, but is only 18 miles wide. Astronomers have discovered the "most massive neutron star ever measured," amassing to more than two times the mass of our ...
