Scientists Find Symmetric Supernova Remnant in Milky Way

Astronomers reveal Pa 30, a star explosion remnant from 1181 that defies physics with perfect symmetry.

In brief

Astronomers reveal Pa 30, a star explosion remnant from 1181 that defies physics with perfect symmetry. Scientists observed a 1181 supernova remnant in Cassiopeia that shows perfect symmetry despite violent explosion. Originally reported by Futurism.

Historical Supernova Observation

Pa 30, the likely remnant of the historical supernova witnessed in the year 1181.

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

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.

The main idea

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