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.

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 ...

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 ...

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 ...

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

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 ...

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 once struggled to measure the true size of the universe. Then came the discovery of Type Ia supernovae — explosions so consistent in brightness they could serve as “standard candles.” By ...
