Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of ...

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

Neutron star mergers are among the most extreme events in the Universe. A recent simulation shows that the cataclysm begins well in advance. Indeed, a chaotic ballet of their magnetic fields ...

Scientists report a possible pulsar at the Milky Way’s center, discovered through radio observations by the Breakthrough Listen team using the Green Bank Telescope, offering a new laboratory for ...

Neutron stars are formed when giant stars run out of fuel. Their internal pressure is no longer sufficient to fight gravity, and the resulting collapse and supernova explosion leaves a tiny core, with ...

Artist’s impression of the powerful winds blowing from the bright X-ray source GX13+1. The X-rays are coming from a disc of hot matter, known as an accretion disc, that is gradually spiralling down to ...
