    A first-of-its-kind, animated map has revealed fresh secrets about a mysterious, flowering "zombie star" lurking in the remnant of a supernova that lit up Earth's skies more than 800 years ago. Today, researchers know that what was once called a “guest star” was actually a powerful supernova, or exploding star, known as SN 1181. However, its origin remained a mystery until 2021. @LiveScience has more: https://flip.it/8XzuLw

    1. Supernova that lit up Earth's skies 843 years ago has a flowering 'zombie star' at its heart — and it's still exploding
      A new animated map sheds light on the superhot "zombie star" at the heart of a nebula leftover from a distant supernova witnessed by astronomers in 1181. The remains of the stellar explosion are unusually wonky and are still exploding at a constant speed.
