In 2006 a star exploded 50 billion times brighter than our sun. New research suggests it wasn't one star, but two. When you purchase through links on our site, we may earn an affiliate commission.

Learn about what may be the first ever superkilonova ever observed, emitting gravitational waves that hint at the collision of two dead stars.

For six months in 1181, a dying star left a mark in the night sky. The striking object appeared as bright as Saturn in the vicinity of the constellation Cassiopeia, and historical chronicles from ...

Two stars are on a collision course and the resulting crash will trigger one of the most powerful forces in nature: a supernova. A team of astronomers at the European Southern Observatory spotted the ...

We've finally unraveled the cause of a mysterious cosmic death. When a star reaches the end of its life and explodes in a supernova, the explosion leaves behind a patch of hot gas and high-energy ...

Astronomers have found dramatic evidence that a black hole or neutron star spiraled its way into the core of a companion star and caused that companion to explode as a supernova. The astronomers were ...

In September 2006 the brightest exploding star — or supernova — ever seen was spotted in a galaxy 240 million light years from Earth. Dubbed SN 2006gy, it was 100 times brighter than a typical ...

A supernova intrinsically two to three times brighter than any previously recorded has been observed, and its characteristics suggest it did not form like others of its class. It appears to have been ...

Astronomers have detected the brightest supernova yet, twice as bright as any seen before. So bright, in fact, that the explosion released tens of times the energy that the Sun will produce in its ...

Scientists have simulated the violent collisions between supernovae and its surrounding gas -- which is ejected before a supernova explosion, thereby giving off an extreme brightness. In a unique ...

The Very Large Array Sky Survey gave astronomers the first clue that ultimately revealed a dramatic story -- the remnant of a star that exploded long ago had plunged into the core of its companion ...
