One of the largest known stars in the cosmos is poised for catastrophe. After witnessing the massive object undergo a ...

One of our universe's biggest stars has dramatically turned into a rare, yellow 'hypergiant' star, and astronomers aren't sure when it will go supernova.

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.

Scientists have revealed for the first time a jaw-dropping early view of an exploding supernova. Observations with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed ...

Astronomers say one of the universe’s largest stars has dramatically changed since 2014, possibly entering a rare final phase that could end in a spectacular supernova explosion.

An international team of astronomers has carried out photometric and spectroscopic observations of SN 2024abvb—a recently ...

This artist's animation shows a hypothe sized event known as a superkilonova . Initially, a massive star explodes in a supernova, which generates elements like carbon and iron. In the aftermath, two ...

NASA has released an unprecedented time-lapse video showing the evolution of Kepler’s Supernova Remnant, a cosmic relic of a massive stellar explosion. Captured by the Chandra X-ray Observatory over ...

A distant stellar explosion has offered astronomers a rare natural experiment, one that turns gravity into a powerful optical tool. The object, known as SN 2025wny, appears not once but four times in ...

The image of the supernova SN 2022esa (marked by the cross) with its host galaxy, 2MFGC 13525, taken by the Subaru telescope on 2023 June 13. At this late phase (about a year after the discovery), the ...
