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.

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

A cosmic mystery surrounding the universe's most dazzling explosions, superluminous supernovas, appears to have been solved by scientists studying a colossal stellar event a billion light-years from ...

Astrophysicists have identified the cause behind a super-bright supernova in a galaxy a billion light-years away, linking its luminosity to a rapidly spinning magnetar and the twisting of space-time.

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 ...

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 ...
