Red Spider Nebula (NGC 6537)
A bipolar planetary nebula in the constellation
Sagittarius. It is centered on one of the hottest
white dwarfs ever observed, probably
a member of a binary system. Stellar winds
have been measured blowing from the central stars at over 300 km/s. These
hot winds expand the nebula, flow along the nebula's walls, and cause gas
and dust to collide. The image shown here was taken by the Hubble Space
Telescope. Compare with the Bug Nebula.
