A Northwestern University-led team of astronomers used NASA’s James Webb Space Telescope to discover a former star that ...

NASA has detected a precursor or progenitor to a supernova for the first time – and it's all thanks to old photos.

NASA’s James Webb Space Telescope has identified the earliest known supernova, which exploded when the universe was approximately 730 million years old. The supernova, designated GRB 250314A, was ...

NASA’s James Webb Space Telescope captured the first published detection of a supernova progenitor in galaxy NGC 1637, revealing a red supergiant star before explosion.

The light from the explosion did not reach Earth till June 29, 2025, when the All-Sky Automated Survey for Supernovae ...

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 ...

Forty million years ago, a star in a nearby galaxy exploded, spewing material across space and generating a brilliant beacon of light. That light traveled across the cosmos, reaching Earth June 29, ...

NASA has released a stunning new image of what appears to be a colossal “cosmic hand” stretching across 150 light-years of space, shaped by one of the galaxy's most powerful electromagnetic engines.

The James Webb Space Telescope spots evidence of a stellar explosion that could help solve the cosmic mystery of "missing red supergiants." ...

Astronomers report a supergiant star in the Andromeda Galaxy, M31-2014-DS1, collapsed directly into a black hole without a supernova, confirming predictions of failed stellar explosions.

(Phys.org) —These delicate wisps of gas make up an object known as SNR B0519-69.0, or SNR 0519 for short. The thin, blood-red shells are actually the remnants from when an unstable progenitor star ...
