APOD 2.7: Spiral Planetary Nebula



The mind-blowing picture of nebula NGC 5189, also known as the Spiral Planetary Nebula (and recently called the Christmas Ornament Nebula), was recently taken by the Hubble Heritage Team. To me, this nebula resembles an approaching celestial lion, stepping forward, his tail curled up and around.

NGC 5189 is a highly complex nebula observed by the Hubble Space Telescope; it is a dying star that is part of a binary star system with a slowly-moving symmetry axis. The nebula spans about three light years and is 3,000 light years away from Earth, near the southern Fly constellation. Previous research done on NGC 5189 showed that the nebula is descended from epochs of "material outflow," lik a bright torus running across.
