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

"Most of the external layers of a massive star are removed during the supernova, but some material falls back, making the neutron star spin faster." When you purchase through links on our site, we may ...

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

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 ...

Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's ...

Astronomers have discovered an extraordinary celestial system containing a runaway pulsar fleeing the scene of a massive stellar supernova explosion. What makes this system even more spectacular is ...

I was exploding with excitement to ask my friend Guy Worthey about supernovas. He’s an astronomer at Washington State University. He told me a supernova is a very energetic explosion in space. There ...

A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...
