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

Here is a look at just a few of the biggest developments in astronomy that The Debrief has been tracking in 2025.

A double explosion, in which a dying star split, then recombined, may be a long-hypothesized but never-before-seen "superkilonova." ...

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 ...

A research team led by Caltech may have just discovered the first-ever superkilonova, a cosmic phenomenon in which a star ...

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 traced a mysterious 'scar' of ionized gas around the solar system to two stars that had a close flyby with our ...

The universe is filled with all kinds of explosions - stars dying, black holes feeding on matter, triggering bright eruptions, galaxies clashing with each other and more. Now, scientists are hoping to ...

Nearly 4.5 million years ago, two enormous, blazing stars swung close to the solar system. They did not touch the sun, but they came close enough to leave a permanent mark on the thin mist of gas that ...

Look up at the sky on a clear night, and you’ll see thousands of stars – about 6,000 or so. But that’s only a tiny fraction of all the stars out there. The rest are too far away for us to see them.
