NGC 6302 (also called the Bug Nebula or Butterfly Nebula [1]), is a planetary nebula in the constellation Scorpius. It is one of the most interesting and complex planetary nebulae observed. The spectrum of NGC 6302 shows it to be one of the hottest objects in the galaxy, with a surface temperature in excess of 200,000K, implying that the star from which it formed must have been very large.
The central star has never been observed and is surrounded by a particularly dense equatorial disc composed of gas and dust. This dense disc has caused the star's outflows to form a bipolar structure [2], similar to an hourglass.
