supernova

A Hawaii telescope just captured a sun-like star's glowing gas layers as it expands. The resulting butterfly-shaped nebula is a sight to behold.

The T Coronae Borealis nova will soon burst into life above our heads for the first time in 78 years.

Citizen scientists have discovered what may be a brown dwarf racing through the cosmos at around 1.2 million miles per hour. Now astronomers want to know what launched it.

While headlines around the world claimed that ancient galaxies discovered by the James Webb Space Telescope were "breaking" our understanding of the Big Bang, the truth is much more nuanced — and much more interesting.

A "guest star," briefly seen in 1181, was created by colliding dead stars, according to new simulations that may finally solve an 800-year-old cosmic mystery.

The physicist César Lattes, who is honored today (July 11) in a Google Doodle, is famous across Latin America for his discovery of the pion — a subatomic particle produced by shockwaves from exploding stars.

A low-mass star has been discovered racing through the Milky Way at over a million miles per hour, a journey that began with either the supernova explosion of a vampire star or an encounter with black holes.

The James Webb Space Telescope has spotted a supernova dating to just 1.8 billion years after the Big Bang, as well as 80 others in the early universe. The ancient explosions could help scientists figure out the mysteries of how the cosmos evolved.

The James Webb Space Telescope has caught a snapshot of two massive asteroids colliding in a nearby star system — and it could teach us about how common solar systems like our own are.

Images from the James Webb Space Telescope and the Chandra X-ray Observatory have been combined to reveal how the Crab Nebula's neutron star is changing.
