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.

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, ...

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.

Using the NASA/ESA/CSA James Webb Space Telescope, astronomers have for the first time identified the progenitor of a nearby supernova -- a red supergiant star cloaked in thick, dust-rich shrouds that ...

Recently, the Hubble Space Telescope captured a before-and-after image of a star exploding brightly. With the images one year apart, the contrast shows how bright a supernova is, and how that ...

Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's ...

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 just released a new image from its Webb Space Telescope of renowned supernova SN 1987A, located 168,000 light years away in the Large Magellanic Cloud. It was first discovered in February 1987, ...

A new video provides a front-row seat to a cosmic drama that has been playing out for centuries. Since 1604, when astronomers around the world recorded a new 'star' that appeared in the sky, humans ...

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 team discovered the star by analyzing archival data from NASA’s NEOWISE mission. They used a prediction from the 1970s ...
