NGC 3132 Eight Burst Nebula

NGC 3132 is nearly half a light year in diameter, and at a distance of about 2,000 light-years in the constellation Vela is one of the nearest known planetary nebulae.

Two very close central stars can be seen within the nebulosity, one of 10th magnitude, the other 16th. The angular separation between these is only 1.7 arc-sec.
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.
