NGC 3132

NGC 3132 (also known as the Eight-Burst Nebula,[2] the Southern Ring Nebula[2], or Caldwell 74) is a bright and extensively studied planetary nebula in the constellation Vela. Its distance from Earth is estimated at about 613 pc. or 2,000 light-years.[2]

Planetary nebula nucleus (PNN)

Images of NGC 3132 reveal two stars close together within the nebulosity, one of 10th magnitude, the other 16th. The central planetary nebula nucleus (PNN) or white dwarf central star is the fainter of these two stars. This hot central star of about 100,000 K has now blown off its layers and is making the nebula fluoresce brightly from the emission of its intense ultraviolet radiation.

gollark: I should be on later today I guess.
gollark: Evil idea: make a GPS server which responds accurately when known GPS tester computers ping it and otherwise lies.
gollark: Want it in CCIM or my base?
gollark: Sure I guess.
gollark: <@114827439070248961> Sure. With some trilateration it may even be possible to accurately locate a misbehaving GPS server.
