C39 (NGC 2392)
This stellar relic was first spied by William Herschel in 1787. The fuzzy outer region is a disk of material embellished with a ring of comet-shaped objects, with their tails streaming away from the central, dying star. The inner nebula also contains some fascinating details. Although this bright central region resembles a ball of twine, it is, in reality, a bubble of material being blown into space by the central star's intense "wind" of high-speed material.
