Data collected by NASA's Chandra X-ray Observatory have revealed that a supernova shock wave traveling through the Cassiopeia A nebula is not expanding as evenly as it should be.

Data from three space telescopes help tell the story of Eta Carinae's explosion.

A new study into the Local Bubble, a cosmic void surrounding Earth, has mapped out the star-forming regions on the bubble's surface and uncovered more information about its explosive birth.

Scientists watched a red supergiant star go supernova in real time, and it was far more violent than they were expecting.

Astronomers discover that two large clouds of gas in the Taurus and Perseus constellations are separated by a 500 light-year-long 'cavity', thanks to an ancient supernova.

Mysterious 'empty sky' gamma-ray bursts could be the work of distant supernova explosions, a new model suggests.

In the 12th century, Chinese and Japanese astronomers spotted a supernova in the sky shining as brightly as Saturn.

Scientists predict that an ancient supernova will reappear in the sky for a 4th time in the year 2037, thanks to the meddling influence of dark matter.

A distant supernova previously imaged by the Hubble Space Telescope will be visible again from Earth and surrounding space in 2037, astronomers predict.

Astronomers have uncovered evidence of explosions triggered by dead stars ramming into live stars, possible proof of a new type of supernova, a new study finds.
