    The Little Ghost Nebula is a planetary nebula. Nothing to do with planets, but they looked like planets in 18th century telescopes. Planetary nebulae form when a star like the Sun runs out of hydrogen and swells into a red giant, throwing off the outer layers of atmosphere. This often happens fairly symmetrically.
