Take a gander at the other nebulae that are all dressed up for Halloween.Yesterday, the Hubble Telescope warned us of impending doom from Sauron's Eye, but it's hardly the only astronomical body making us nervous. There's the Cat's Eye Nebula, staring at us with its unblinking gaze, the arachnophobia-inducing Tarantula and Red Spider Nebula, the Ghost of Jupiter (our gas giant's spectral doppelganger), and the eerie apparitions contained in the Ghost Head and Little Ghost Nebulae.
