Using Georgia State’s CHARA Array, an international team of scientists has uncovered unexpected complexity in how stars ...

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

A strange cosmic blast that lit up the sky in two distinct acts is forcing astronomers to rethink how stars live and die. The event, tagged AT2025ulz, appears to be the first known case where a ...

A supernova from the early universe looks unexpectedly familiar, challenging ideas about how the first massive stars lived ...

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

For years, telescopes have been finding extremely energetic blue stellar explosions that could not be explained until now.

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

A violent stellar explosion has just given astronomers their clearest look yet at how some of the raw ingredients for biology are forged in space. By dissecting the debris of a recent supernova and ...

For the first time in history, researchers observed a dying star stripped nearly to its bare core before it exploded. This newly discovered supernova, designated SN 2021yfj, offers an unprecedented ...

For years, astronomers talked about coronal mass ejections on other stars almost like ghost stories. You hear signs, hints and clues, but never the thing itself. Our own Sun throws these storms often.

A team of astronomers including George Washington University physics Ph.D. student Eliza Neights recorded an extraordinary cosmic outburst this July which likely heralds a new kind of stellar ...
