A cosmic explosion with an energy equivalent to the output of a billion suns went unnoticed by astronomers until they caught ...

WASHINGTON, March 11 (Reuters) - A supernova - the explosion marking the end of a massive star's life - is one of the ...

Astronomers have discovered that the birth of neutron stars with magnetic fields trillions of times stronger than Earth's magnetosphere is the "magic trick" behind superbright supernovas.

The light did not fade the way it was supposed to. After blazing into view about a billion light-years from Earth, the ...

Astronomers have detected strange "wobbles" in the light curve of a super bright supernova, hinting that a magnetar was born inside the extreme stellar explosion.

Astronomers have discovered a strange new signal coming from an exploding star — a “chirp” that speeds up over time, similar to the signals seen when black holes collide. The unusual pattern appeared ...

Superluminous supernovas are the brightest stellar explosions in the universe. Astronomers may have found a mechanism that ...

It was only last October that telescopes spotted a gamma ray burst—caused by the collapse of a black hole—that was so ...

The discovery of a newborn magnetar inside a distant supernova helps explain why some stellar explosions shine far brighter ...

Astronomers may have found an exciting new clue about dark energy—the mysterious force driving the universe’s accelerating expansion. They discovered an extraordinarily bright supernova from more than ...

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

This violent fate is rare: fewer than about 1% of stars are big enough to end their lives this way. Indeed, these dramatic explosions only occur in so-called “massive stars”. These are stars with a ...
