Saturn Nebula (NGC 7009)
Like the Blinking Nebula, the Saturn Nebula has a bright central star at the center of a dark cavity bounded by a football-shaped rim of luminous gas. The cavity and its rim are trapped inside smoothly-distributed material in the shape of a barrel and comprised of the star's former outer layers. At larger distances, and lying along the long axis of the nebula, a pair of ansae, or "handles," each joined to the tips of the cavity by a long jet of material. The photo shown here was taken by the Hubble Space Telescope.
