The James Webb Space Telescope has spotted a stellar explosion from a time when the cosmos was still in its infancy, catching ...

The closest cosmic explosion to Earth in the last 10 years became a record breaker for the Search for Extraterrestrial Intelligence Institute (SETI). The supernova, designated (SN) 2023ixf, was first ...

Scientists using the James Webb Space Telescope (JWST) have made an unprecedented breakthrough, capturing the most distant ...

In A.D. 185, ancient Chinese astronomers observed a bright new object burst onto the scene in the night sky. The beacon remained visible to the naked-eye for more than eight months, leading the ...

The shredded remnants of the first supernova ever recorded by humans — which appeared in the sky more than 1,800 years ago and vanished within eight months — rise from the cosmic grave in a stunning ...

Astronomers using the James Webb Space Telescope have detected the most distant supernova ever observed, offering new ...

A new telescope image has shed light on the ghostly remains of the first recorded supernova. More than 1,800 years ago, in the year 185, Chinese astronomers recorded what they called a “guest star” ...

A mysterious remnant from a rare type of supernova recorded in 1181 has been explained for the first time. Two white dwarf stars collided, creating a temporary 'guest star,' now labeled supernova (SN) ...

A puzzling cosmic blast detected in both light and gravitational waves may hint at a previously unseen type of explosion, ...

In early December 185 CE, Chinese astronomers recorded a bright “guest star” in the night sky that shone for eight months in the direction of Alpha Centauri before fading away—most likely the earliest ...

This illustration charts the evolution of the SNR 1181 remnant, from its creation when a carbon-oxygen-based white dwarf and oxygen-neon white dwarf merged, to the formation of its two shock regions.
