A superkilonova candidate event, named AT2025ulz, was observed in 2025; LIGO and Virgo first spotted gravitational waves, ...

Astronomers may have discovered the first example of an explosive cosmic event called a "superkilonova," in the form of a gravitational wave signal detected on Aug. 18, 2025.

A massive star may have burst, leaving behind two dense, dead cores, which then collided and caused another explosion ...

"The sheer amount of radiated energy from these bursts is so large that you can't power them with a core collapse stellar explosion — or any other type of normal stellar explosion." ...

It's just a matter of time before a dead star reignites in space 3,000 light years away. And you'll be able to see it with the naked eye despite the distance. Astronomers say when the explosion ...

Latvian tennis player Jelena Ostapenko has been forced to deny accusations of racism after she exploded at her victorious Chicago rival Taylor Townsend in a bitter courtside tirade following a U.S.

The new paper argues that, in SN 1181, the first phase of the supernova fizzled out and left behind an unusually active ...

WASHINGTON, Nov 12 (Reuters) - The explosive death of a star - a supernova - is among the most violent cosmic events, but precisely how this cataclysm looks as it unfolds has remained mysterious.

Scientists have revealed for the first time a jaw-dropping early view of an exploding supernova. Observations with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed ...
