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

What can imaging supernovae (plural for supernova) explosions teach astronomers about their behavior and physical ...

The results indicate that the elements essential for life formed within extreme, highly energetic environments deep inside stars, far removed from the calm conditions required for life itself. The ...

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

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

"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 ...

Astronomers have spotted another never-before-seen "nova" blaze to life in the night sky. This may be the first time that simultaneous stellar explosions have been visible to the naked eye in recorded ...

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

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

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.
