Using the James Webb Space Telescope (JWST), a team of astronomers has found the earliest known supernova, one which exploded when the universe was just 730 million years old. This observation ...

An international team of astronomers has achieved a first in probing the early universe, using the James Webb Space Telescope (JWST), detecting a supernova – the explosive death of a massive star – at ...

Astronomers using the James Webb Space Telescope (JWST) may have discovered the most distant supernova in the universe. This stellar explosion, hosted by a very faint galaxy, occurred when the ...

The big picture: NASA's James Webb Space Telescope recently managed to capture imagery of the oldest and farthest known supernova explosion – an event that occurred when the universe was just 730 ...

The supernova (dubbed SN 2025kg or affectionately known as "the kangaroo") increased in brightness over several weeks before fading. "The JWST obtained exquisite infrared spectra when 'the kangaroo' ...

The James Webb Space Telescope has observed the oldest known supernova—the explosive death of a star that lived when the universe was only 730 million years old. The ancient blast occurred when the ...

An international team of astronomers, working with researchers from University College Dublin and other institutions, has detected a supernova from an era once thought far beyond reach. Using the ...

Using a combination of telescopes, astronomers have characterized the closest supernova linked to a fast X-ray transient. The observations reveal that these bright blasts of X-rays may be the result ...

Earlier this year, a powerful gamma-ray burst traveled through space from a very distant source in the cosmos. The explosion was traced back to the early universe, just millions of years after the Big ...
