Just in time for Halloween, astronomers have discovered a nebula that looks like the profile of a wicked witch.The star cluster is a massive cloud of gas reflecting light from nearby stars. It's also a stellar nursery. The red dots on the witch's warty chin are stars being born.The image was taken by the Wide-field Infrared Survey Explorer, or WISE, a space-based telescope that surveyed the entire sky in 2010 and early 2011.The Witch Head nebula is estimated by the Jet Propulsion Laboratory to be hundreds of light-years away in the Orion constellation, just off the famous hunter's knee.WISE was recently "awakened" to hunt for asteroids in a program called NEOWISE.
