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 ...

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” ...

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 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 ...

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) ...

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 ...

The ESO's Very Large Telescope points at the exact position of the supernova remnant SNR 0509-67.5, or "the expanding shells of a star that detonated twice," located in the Large Magellanic Cloud, a ...

This image combines data from four space telescopes to create a multi-wavelength view of all that remains of RCW 86, the oldest documented example of a supernova. Chinese astronomers witnessed the ...

Astronomers Detect Brightest Supernova on Record A team of researchers from the University of Birmingham say they've identified the brightest supernova explosion on record, and it may be a previously ...

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.
