"The best-case scenario for axions is Fermi catches a supernova. It's just that the chance of that is small." When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

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

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. This artist's concepts shows a hypothesized event known as a superkilonova. A massive star explodes in a supernova (left), which ...

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 ...

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 ...

Axions are the most likely candidate for enigmatic dark matter that dominates the universe. Astrophysicists are searching for evidence of high-mass axions produced during supernovae. Scientists ...

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 ...

A “disappearing” star in the Andromeda galaxy is the closest and best candidate for a newborn black hole that astronomers have ever seen ...

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 ...
