The temperature of elementary particles has been observed in the radioactive glow following the collision of two neutron stars and the birth of a black hole. This has, for the first time, made it ...

A record-shattering stellar blast has been caught on camera in unprecedented detail, and the footage is forcing astronomers to rethink how stars die. The event, linked to an extreme gamma-ray outburst ...

The blast may have been a kilonova — a type of neutron star merger — in the wake of a more traditional supernova.

Do dead stars glow? A strange gravitational phenomenon could be generating enormous amounts of light around neutron stars, new research suggests. When you purchase through links on our site, we may ...

A tiny, dense stellar corpse in a nearby galaxy is pumping out so much energy that, on paper, it should have blown itself ...

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 ...
