ATLANTA — 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 ...

A star system in our own galactic neighborhood is poised to put on a show so bright it could briefly rival the planets and even shine in daytime skies. Astronomers are watching for a sudden eruption ...

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 ...

A new discovery about what happens when a supernova – an exploding star – and a black hole collide could change the way scientists understand the lives and deaths of stars. The finding was the first ...

According to scientists, red supergiant stars should produce more supernovas. But astronomers just aren’t spotting them. Here's how they plan to crack the case.

Dying massive stars can reverse their spin deep inside, reshaping how scientists predict supernovas and stellar collapse.
