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

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

In a series of observations that read like science fiction, astronomers now suspect they have watched a star quite literally ...

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

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 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.

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

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

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 ...

Astronomers have captured images of two stellar explosions—known as novae—within days of their eruption and in unprecedented detail. The breakthrough provides direct evidence that these explosions are ...

Crab Nebula reveals gas from ancient supernova explosion Betelgeuse shows late-stage evolution of a massive star Stellar death spreads elements, triggering new star formation ...
