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 ...

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

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

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

JWST uncovers evidence of ancient “monster stars” whose extreme chemistry may explain the origins of early supermassive black holes.

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 ...

Astronomers are uncovering vast, wheel-shaped structures in the cosmos that challenge long-held ideas about how galaxies grow ...

Long, long ago a cloud of stars circled a galaxy-size black hole, safely at a distance. Then about 200 million years ago one ...

When the Kepler space telescope malfunctioned last spring, it looked as though its incredibly successful planet-hunting mission might be over—and NASA made that sad fact official a few months later.

Beyond better testing, we need better protection. Physical shields seem like the obvious first defense. Hydrogen-rich materials such as polyethylene and water-absorbing hydrogels can slow charged ...

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.
