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

In 1181 AD, a bright "guest star" was observed to linger in the sky for around six months. Nearly 850 years later, the likely ...

The James Webb Space Telescope has spotted a stellar explosion from a time when the cosmos was still in its infancy, catching the light of a supernova that detonated less than a billion years after ...

A superkilonova candidate event, named AT2025ulz, was observed in 2025; LIGO and Virgo first spotted gravitational waves, ...

Astronomers have confirmed the most distant supernova, SN in GRB 250314A, which exploded just 730 million years after the Big Bang, using the James Webb Space Telescope.

Astronomers have observed the calamitous result of a star that picked the wrong dance partner. They have documented what appears to be a new type of supernova, as stellar explosions are known, that ...

Swift observations with the European Southern Observatory's Very Large Telescope (ESO's VLT) have revealed the explosive death of a star just as the blast was breaking through the star's surface. For ...

One such superkilonova candidate event, named AT2025ulz, was observed in 2025; LIGO and Virgo first spotted gravitational waves, while the Zwicky Transient Facility was the first to detect light from ...

A dozen luminous blue outbursts were thought to be unusual supernovae. A new outburst, the brightest yet, suggests it's ...
