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.

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 ...

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 ...

Astronomers may have seen a space event that has never been clearly confirmed before. It is called a superkilonova, and it may have been detected in August 2025. The event happened very far from Earth ...

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 ...

"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 ...

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 ...
