Astronomers have found a remarkable pair of stars that may finally prove a long-debated theory. Described in the journal ...

Astronomers from the Yunnan University in China and other institutions have carried out photometric and spectroscopic observations of a recently detected supernova designated SN 2024aecx. Results ...

The SN 1181 remnant is not the usual supernova remnant. It has a “zombie star” at its heart. This is a dense, dead star called a white dwarf that triggers a thermonuclear explosion resulting in a ...

In a paper published in The Astrophysical Journal Letters, researchers studied Parker's Star Nebula 30 (Pa 30), the type Iax supernova remnant associated with supernova 1181 (SN 1181).The nebula ...

Known today as supernova SN 1181, this “zombie star” has remained a scientific curiosity for centuries and has recently resurfaced as a subject of interest for entirely new reasons. For years, the ...

This one—called “Parker’s Star,” the remnant of the supernova SN 1181, named for the year it appeared in Earth’s skies—lies about 8,000 light-years from our solar system, ...

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.

When a supernova was seen glittering in the night sky for six months in 1181, it was so bright that Chinese and Japanese astronomers recorded it as a "guest star" in the Cassiopeia constellation.Now, ...
