An international team analyzed data from NASA's Fermi space telescope and detected gamma rays from a rare and exceptionally ...

NASA's Fermi Gamma-ray spacecraft has observed a super-bright, supercharged supernova explosion powered up by the creation of a highly magnetic dead star, or magnetar.

A dying massive star does not go quietly. Its core collapses, matter crashes inward, neutrinos pour out in staggering numbers ...

NASA’s Fermi telescope may have finally uncovered the magnetic powerhouse behind the universe’s brightest supernovae.

One of the biggest questions in the scientific world right now revolves around something we can't see, and can't directly detect in any other way either. Based on the movements of galaxies, ...

A supernova at least twice as bright and energetic, and likely much more massive than any yet recorded has been identified by an international team of astronomers, led by the University of Birmingham.

Chandra X-ray telescope imagery of Kepler’s Supernova Remnant has been time-lapsed to show 25 years of growth. Credit: ...

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 ...

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 supernova exploding in a nearby galaxy is providing an unexpected spectacle for amateur astronomers. The supernova, which appeared in the Pinwheel Galaxy 21 million light-years away, is one of the ...
