Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old.

A research team led by Caltech may have just discovered the first-ever superkilonova, a cosmic phenomenon in which a star ...

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

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.

Astronomers have obtained remarkably detailed images of two stellar explosions -- called novae -- just days after they began.

"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." When you purchase ...

James Webb has spotted the most distant supernova ever seen, exploding just 730 million years after the Big Bang, offering ...

A dozen luminous blue outbursts were thought to be unusual supernovae. A new outburst, the brightest yet, suggests it's ...

A record-bright LFBOT exposes violent encounters between black holes and stars, helping astronomers understand extreme black ...

In a series of observations that read like science fiction, astronomers now suspect they have watched a star quite literally ...

Gravitational wave observatories have been studying black holes that are in the right range to be the source of these LFBOTs. So far, though, no black hole collision has been seen with light-based ...
