NGC 6302 is a high excitation multi-polar
planetary nebula first studied by Emerson Barnard in 1907. The
complex planetary nebula is approximately 1900 years old and is
expanding at 600 KM/sec. A dark lane extends across the waist
of the nebula and obscures the hot central star at optical wavelengths.
The nature of the central star is unknown but evidence suggests
it's progenitor was a massive sun of 5 to 6 solar masses. Its
spectrum suggests a surface temperture of 200,000 K, making it
one of the hottest objects in the galaxy.
