Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old.

An international team of astronomers has achieved a first in probing the early universe, using the James Webb Space Telescope ...

Astronomers have observed what they are calling a new type of supernova, which has provided an unparalleled glimpse into what happens deep within a star just before it explodes. A study detailing the ...

James Webb has spotted the most distant supernova ever seen, exploding just 730 million years after the Big Bang, offering ...

When astronomers observe a supernova, they typically see strong indications of light elements like hydrogen and helium. Layers of elements including carbon, oxygen, neon, and magnesium are also ...

This timelapse video using data from NASA’s James Webb Space Telescope highlights the evolution of one light echo in the vicinity of the supernova remnant Cassiopeia A.

An image from NASA's Chandra X-ray observatory shows a glowing hand stretching across the cosmos with its palm and fingers sculpted from the wreckage of a massive stellar explosion. When you purchase ...

A novel type of supernova, SN2021yfj, has been discovered, exhibiting an unusual spectral signature rich in silicon, sulfur, and argon, unlike typical supernovae which display lighter elements.

The most dangerous parts of a supernova explosion are the outputs like X-rays and gamma rays. Even though they only share a small fraction of a supernova's power, they are extremely dangerous. But ...

Astronomers have, for the first time, recorded the moment a star’s explosion broke through its surface. The nearby supernova, SN 2024ggi, revealed a surprisingly olive-shaped blast when studied with ...

When one supernova commenced, it looked like an olive — at least before it got shaken and stirred. This insight, reported in the Nov. 12 Science Advances, comes from new observations taken in the wake ...

The supernova was the death of a red supergiant star 500 times larger than the sun, in a galaxy just 22 million light-years away. When you purchase through links on our site, we may earn an affiliate ...
