Supernova remnants (SNRs) are the remains of a supernova explosion, seen as diffuse, expanding structures. Observations show that SNRs harbor ejected material expanding from the supernova ...

A pair of white dwarfs, located just 150 light-years from Earth, appears doomed to die in a type 1a supernova that will shine brighter than anything currently visible in the night sky. But ...

The explosion is not due for another 23 billion years, however, and despite being so close to our solar system, this supernova will not endanger our planet.

Unlike a supernova, which destroys a dying star, the dwarf star remains intact after the nova explosion. It does, however, blast the material into space in an explosive flash that’s bright ...

In 2024, Tim Cunningham at the Harvard Smithsonian Center for Astrophysics studied an unusual supernova remnant called SN 1181. It has a striking structure quite unlike any previously seen.

That seems to clinch the connection between SN 1181 and Pa 30. But the research also revealed some new mysteries to unravel. A still of the animation created of Pa 30. (W.M. Keck Observatory/Adam ...

A supernova event recorded by Chinese and Japanese astronomers in 1181 is at the heart of a first-of-its-kind 3D animated map, unveiling new secrets of a flowering “zombie star.” ...
