  • Fun Facts
  • The Cat's Eye Nebula was discovered by William Herschel on February 15, 1786.
  • The centre of the nebula contains a bright star, possibly a binary system, and one of them might be a Wolf-Rayet star.
  • The surface temperatures of known Wolf–Rayet stars range from 35,000 °F to around 377,000 °F, hotter than almost all other kinds of stars.
  • Planetary nebulas are a type of nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives.
