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

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

A distant stellar explosion has offered astronomers a rare natural experiment, one that turns gravity into a powerful optical tool. The object, known as SN 2025wny, appears not once but four times in ...

Astronomers report a strange cosmic blast that looked like a kilonova, then behaved like a supernova, hinting at a possible first “superkilonova” and leaving scientists debating how stars truly die.

AUSTIN (KXAN) — The insides of a star are on full display thanks to an explosion. New research published this month in Nature is revealing the details of a star’s core. “This is the first time we have ...

A superkilonova candidate event, named AT2025ulz, was observed in 2025; LIGO and Virgo first spotted gravitational waves, ...

This artist’s impression shows a star going supernova. About 22 million light-years away the supernova, SN 2024ggi, exploded in the galaxy NGC 3621. Using the ESO’s Very Large Telescope, astronomers ...

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.

Twinkle, twinkle, little star. How I wonder what you, wait a minute, why are you twinkling so much? Um, guys, that's no ...

Astronomers find an explanation for the fastest stars in the galaxy while uncovering a new mechanism for a supernova explosion. Credit: Technion illustration Astronomers call a special kind of ...
