Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed ...

It's never too late to solve a cold case. A new paper from Syracuse University researchers proposes an explanation for both a mysterious stellar object discovered in the year 2013 and an astronomical ...

NASA's Chandra X-ray Observatory releases its longest-spanning video of X-ray data yet. Credit: NASA / CXC / SAO / Pan-STARRS Astronomers have turned a famous star explosion into a 25‑year time‑lapse, ...

Astronomers have created a detailed forecast of where they expect to observe future stellar explosions in a nearby galaxy, opening a new window into how exploding stars shape the cosmos. Focusing on ...

Many stars die spectacularly when they explode as supernovae. During these violent explosions, they leave behind thick, chaotic clouds of debris shaped like cauliflowers. But supernova remnant Pa 30 ...

Astronomers have turned a famous star explosion into a 25‑year time‑lapse, using a NASA telescope to watch the superheated gas race through space and slam into its surroundings. The new study using ...

In a series of observations that read like science fiction, astronomers now suspect they have watched a star quite literally pull itself apart. Instead of a neat, textbook explosion, the dying object ...

A double explosion, in which a dying star split, then recombined, may be a long-hypothesized but never-before-seen "superkilonova." When you purchase through links on our site, we may earn an ...

This composite image features X-ray, ultraviolet, optical, and near-infrared data of the luminous fast blue optical transient (LFBOT) named AT 2024wpp. The transient is the bright spot at the upper ...
