Uneven supernova explosions may explain the unusual mix of elements in Milky Way stars once thought to be evidence of hypernovas.

The aftermath of a supernova, a stellar explosion, is usually a slowly fading cloud of hot gas. So when astronomers pointed NASA's Chandra X-ray Observatory at the nearby galaxy Messier 83 (M83), they ...

Hubble observations challenge a leading theory of cosmic reionization, revealing that supernova-driven winds hinder escaping radiation while young stars may have helped illuminate the early universe.

This artist’s animation 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 ...

The new image isn’t just stunning—it may also provide clues about how this star survived its own explosion. Previous images of the explosion’s remnants had also captured a sphere of long, ...

A supernova’s changing rhythm offers evidence of a hidden magnetar, while companion observations reveal surrounding-gas interaction.

A distant star has captured astronomers' attention over the past decade, teasing them with indications that it will soon explode as a supernova. But new research shows that something else entirely is ...

Artist’s impression of a hot core—a warm cocoon of molecular gas surrounding a newborn star—discovered in a supernova remnant. Blue represents high-energy regions produced by the supernova explosion, ...
