Astronomers may have discovered one of the clearest examples yet of a rare "pair-instability" supernova. It is a catastrophic ...

But one massive star, hundreds of times heavier than our Sun, self-destructed so catastrophically that it left behind no ...

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

A massive star in the Andromeda Galaxy, one of the most luminous objects in its neighborhood, has quietly disappeared. Over the span of roughly eight years, the star dimmed by more than 10,000 times ...

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

Astronomers have captured the first radio waves ever detected from a rare class of exploding star, a discovery that has given them an unprecedented look into the final years of a massive star before ...

Is a star about to explode in the night sky? If predictions come true, T Coronae Borealis (T CrB) could become visible for a ...

It's never too late to solve a cold case. A new paper from Syracuse University researchers proposes an explanation for both a mysterious stellar object discovered in the year 2013 and an astronomical ...

This collapse leads to a supernova explosion, leaving behind either a black hole or a neutron star.

Earlier this year, a powerful gamma-ray burst traveled through space from a very distant source in the cosmos. The explosion was traced back to the early universe, just millions of years after the Big ...

In a strange turn of events, a supernova birthed twin baby neutron stars that merged to make a powerful kilonova. Reading time 3 minutes When massive stars die, they go out in fiery explosions called ...
