A mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...

Caltech astronomer Mansi Kasliwal and her colleagues were not expecting to chase a mystery that blurred the line between a supernova and a kilonova. Yet that is where the evidence has led after an ...

Do we live in a supernova graveyard? A team of researchers proposes that 10 million years ago two giant neutron stars crashed into each other and debris from that intense explosion (called kilonova) ...

Merger of two neutron stars in the aftermath of a supernova may have been observed for the first time, though questions ...

(Nanowerk News) When the most massive stars reach the ends of their lives, they blow up in spectacular supernova explosions, which seed the universe with heavy elements such as carbon and iron.

The cosmos has delivered a rare kind of fireworks display, and astronomers are racing to understand what it means. A strange double flash from a distant galaxy appears to show two neutron stars ...

This is an artist’s impression of the first confirmed detection of a star system that will one day form a kilonova — the ultra-powerful, gold-producing explosion created by merging neutron stars.

A strange, ultra-bright flash in a distant galaxy has given astronomers their strongest hint yet that a new class of stellar catastrophe exists. The event, tagged ZTF25abjmnps and also known as ...

This artist's impression shows a kilonova produced by two colliding neutron stars. While studying the aftermath of a long gamma-ray burst (GRB), two independent teams of astronomers using a host of ...

This artist's concepts shows a hypothesized event known as a superkilonova. A massive star explodes in a supernova (left), which generates elements like carbon and iron. In the aftermath, two neutron ...
