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.

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

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 ...

What can imaging supernovae (plural for supernova) explosions teach astronomers about their behavior and physical characteristics? This is what a recent study published in Nature Astronomy hopes to ...

Astrophysicists have achieved an eye-opening leap in understanding stellar death, capturing unprecedented, detailed images of two exploding stars that demonstrate these blasts are far more complicated ...

"The sheer amount of radiated energy from these bursts is so large that you can't power them with a core collapse stellar ...

What can an exploding star in a distant galaxy teach scientists about red supergiants? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team of ...

Astronomers have succeeded in capturing the first direct, high-resolution images of two stars in the immediate aftermath of their explosion, according to Georgia State University. And the breathtaking ...

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 ...

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 ...
