NGC 2392 (also called the Eskimo Nebula or the Clown Face Nebula) in the constellation of Gemini was discovered by William Herschel in 1787.  It is estimated to be 5,000 light years from our solar system, and it is moving away from us at 75 km/sec.  The nebula is expanding at a rate of 60 km/sec.  The Eskimo's "furry parka" (as seen in the Hubble picture) is really a disk of material embellished with a ring of comet-shaped objects, with their tails streaming away from the central, dying star. Scientists are still puzzled about the origin of the comet-shaped features in the "parka." One possible explanation is that these objects formed from a collision of slow- and fast-moving gases.  The Eskimo's "face" resembles a ball of twine, but it is, in reality, a bubble of material being blown into space by the central star's intense "wind" of high-speed material.
