## Historical Supernova Observation
Japanese, Chinese, and Arabic astronomers documented a star explosion in 1181 visible for 185 days.
## Pa 30's Unique Structure
The remnant shows uniform knots of ionized gases with red sulfur and blue-green oxygen filaments.
## Proximity to Earth
Pa 30 lies 7,500 light-years from Earth, a quarter the distance to the Milky Way's center.
## Symmetric Explosion Puzzle
The explosion preserved the progenitor star at the center despite chaotic energy release.
## Zombie Star Explanation
Pa 30 is the only known survivor of a Type Iax supernova where two white dwarfs collided.
## Key takeaway

Scientists observed a 1181 supernova remnant in Cassiopeia that shows perfect symmetry despite violent explosion.
