In its first glimpse of the heavens following the successful December 1999
servicing mission, NASA's Hubble Space Telescope captured a majestic view of a planetary
nebula, the glowing remains of a dying, Sun-like star. This stellar relic, first spied by
William Herschel in 1787, is nicknamed the "Eskimo" Nebula (NGC 2392) because,
when viewed through ground-based telescopes, it resembles a face surrounded by a fur
parka. In this Hubble telescope image, the "parka" is really a disk of material
embellished with a ring of comet-shaped objects, with their tails streaming away from the
central, dying star. The Eskimo's "face" 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. In this photo, one bubble lies in front of the other, obscuring part
of the second lobe. Scientists believe that a ring of dense material around the star's
equator, ejected during its red giant phase, created the nebula's shape. The bubbles are
not smooth like balloons but have filaments of denser matter. Each bubble is about 1
light-year long and
