NGC 2440
About
this Object
Located in the constellation Puppis around 1500 light
years away a star shed its outer gas shell and caused a gaseous
envelope which expanded into space.
Lighting up this gas is one of the hottest stars known, its temperature
nearing 300,000 deg F. The star, a white dwarf, is not resolved
in the image but causes
the central region of this planetary nebula to be extremely
bright.. Click here to see a much more resolved core area taken
