New observations show a star that blew up in two separate bursts, confirming a long-suspected cosmic phenomenon called a ...

Astronomers have taken the first ever image that shows what happens when a star explodes twice in a supernova.

A supernova explosion occurred on July 4, 1054, resulting from the death of a star estimated to be nine to eleven times the ...

The shattered star at the center was once a white dwarf, a stellar ember no larger than Earth, yet almost as heavy as the Sun ...

Supernovae, these gigantic stellar explosions, release a phenomenal amount of energy. This energy travels through space, ...

Betelgeuse dimmed unexpectedly, sparking theories it was about to go supernova. Though it recovered, scientists confirmed it's in the final phase of its life. Its eventual explosion will be visible ...

This star, nicknamed "Betelbuddy" by researchers, may be orbiting Betelgeuse, sweeping away the surrounding stellar dust. This interaction could make the star appear brighter at times, according to ...

Betelgeuse is about 15 to 20 times more massive than the Sun, and stars of this mass are expected to end their lives in a powerful explosion known as a supernova.

No, it wasn't. Rather, scientists suspected that Betelgeuse, a young, chaotic, roiling star that's rapidly evolving, heaved a hunk of its gaseous atmosphere into space in 2019.

This could be possible as Betelgeuse is known to pulsate — expand and shrink, dim and brighten up — at regular intervals. Most obviously, Betelgeuse's brightness swings up and down every 420 days.
