NASA's James Webb Space Telescope finds a red supergiant star before it exploded, offering new clues to why their supernovas ...

Astronomers using the James Webb Space Telescope (JWST) have achieved a remarkable first: capturing a detailed view of a red supergiant star just before it exploded as a supernova. The star, located ...

For the first time, astronomers have spotted a star that exploded not once, but twice. A new image of a roughly 300-year-old supernova provides visual evidence that some dying stars undergo a double ...

Researchers have used machine learning to dramatically speed up the processing time when simulating galaxy evolution coupled with supernova explosion. This approach could help us understand the ...

A new study reveals an intriguing possibility: asupernova explosion might have sent a surge of cosmic rays toward Earth ...

WASHINGTON (Reuters) -Astronomers have observed the calamitous result of a star that picked the wrong dance partner. They have documented what appears to be a new type of supernova, as stellar ...

My hypothesis is that remnants of a supernova—an exploding star —had an impact on Earth's past climate, causing global cooling, between 3 million and 2.6 million years ago and that this indirectly ...

The protocol used to find these young supernova explosions could be used on data from the upcoming Vera C. Rubin Observatory. The early stages of a supernova explosion are revelatory in what they can ...

A supernova event recorded by Chinese and Japanese astronomers in 1181 is at the heart of a first-of-its-kind 3D animated map, unveiling new secrets of a flowering “zombie star.” Supernova Sn 1181 is ...

In 1604, a new star appeared in the night sky that was much brighter than Jupiter and dimmed over several weeks. This event was witnessed by sky watchers including the famous astronomer Johannes ...

For six months in 1181, a dying star left a mark in the night sky. The striking object appeared as bright as Saturn in the vicinity of the constellation Cassiopeia, and historical chronicles from ...
