Astronomers Uncover Unique 'Zombie Star' in Ancient Supernova Remnant

The Pa 30 nebula, linked to the 1181 supernova, reveals an unusual white dwarf remnant with intriguing properties.

The supernova SN 1181, observed in 1181 AD, was recently identified as a Type Iax supernova, leaving behind a rare 'zombie star.'
Researchers used advanced imaging techniques to study the Pa 30 nebula, uncovering its unique filamentary structure resembling a dandelion.
The nebula's filaments are expanding ballistically at about 1,000 kilometers per second, indicating they have not slowed since the explosion.
The explosion appears to have been asymmetrical, contributing to the nebula's irregular morphology and unusual distribution of elements.
The findings prompt new questions about the nature of supernovae and their remnants, challenging astronomers to explore further.
