A double explosion, in which a dying star split, then recombined, may be a long-hypothesized but never-before-seen "superkilonova." ...
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.
The results indicate that the elements essential for life formed within extreme, highly energetic environments deep inside stars, far removed from the calm conditions required for life itself. The ...

Mysterious bright blue cosmic blasts triggered by black holes shredding stars, scientists say. 'It's definitely not just an exploding star.'
"The sheer amount of radiated energy from these bursts is so large that you can't power them with a core collapse stellar ...
Observing the Universe often means contemplating phenomena that occurred millions of years ago. But sometimes, the opportunity arises to capture a cosmic event almost in real-time, as if we were ...

'We were amazed': Scientists using James Webb telescope may have discovered the earliest supernova in the known universe
Astronomers using the James Webb Space Telescope report that a powerful gamma-ray burst detected in March may have been produced by the explosion of a massive star just 730 million years after the Big ...
Solar storms can trigger auroras on Earth. This star’s explosion could destroy a planet’s atmosphere
(CNN) — For the first time, astronomers say they have spotted a giant explosion released by a star beyond our solar system. The eruption was similar in some ways to those unleashed by our sun, such as ...
A rare supernova let scientists glimpse a star's interior, revealing a dense silicon-sulphur shell and unexpected helium that should have vanished earlier. (Nanowerk News) An exploding star has given ...
