A composite image shows the remains of supernova SN 1181, a cataclysmic collision of two stars. The spherical nebula has at its center a hot white dwarf, or "zombie star," left behind after the ...

In 1181 AD, during the Genpei War, a mysterious star appeared in Asia’s skies for a brief time before disappearing again. For 843 years, the cosmic event was a source of confusion for astronomers.

For six months in 1181, a dying star left a mark in the night sky. The striking object appeared as bright as Saturn in the vicinity of the constellation Cassiopeia, and historical chronicles from ...

The search for visual evidence of the supernova, named SN 1181, went on for centuries before amateur astronomer Dana Patchick first discovered its remains in 2013.

Now known as the supernova SN 1181, its remnant has only been traced in 2021 to the nebula Pa 30, found in 2013 by amateur astronomer Dana Patchick while examining an archive of images from the WISE ...

The object, now known as SN 1181, is one of a handful of supernovas documented before the invention of telescopes, and it has puzzled astronomers for centuries.

The object, now known as SN 1181, is one of a handful of supernovas documented before the invention of telescopes, and it has puzzled astronomers for centuries.

A new study has described in detail a dying star initially recorded in 1181. The object may belong to a rare class of supernovas that leaves behind a “zombie star.” A supernova shone in the ...
