For every galaxy that's visible from Earth, there are nine smaller ones that we can't see, even with all the technology we've ...

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.

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

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

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 ...

Learn about what may be the first ever superkilonova ever observed, emitting gravitational waves that hint at the collision of two dead stars.

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 ...

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 ...

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

It's just a matter of time before a dead star reignites in space 3,000 light years away. And you'll be able to see it with the naked eye despite the distance. Astronomers say when the explosion ...

"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 ...
