supernova

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.

Stars die at different rates depending on how they kick the bucket.

Stars that vanish from the sky may be collapsing directly into black holes without going supernova first, a new study of a bizarre binary star system suggests.

The Hubble Space Telescope's stunning image of the dusty 'train-wreck' galaxy NGC 4753 reveals what may be one of the greatest optical illusions in the nearby universe.

With the nature of the universe's two most elusive components up for debate, physicists have proposed a radical idea: Invisible particles called tachyons, which break causality and move faster than light, may dominate the cosmos.
