Butterfly Emerges from Stellar Demise in Planetary Nebula NGC 6302
From Wikipedia: NGC 6302 (also called the Bug Nebula or Butterfly Nebula), is a bipolar planetary nebula in the constellation Scorpius. It is one of the most interesting and complex planetary nebulae observed. The spectrum of NGC 6302 shows its central star is one of the hottest objects in the galaxy, with a surface temperature in excess of 200,000 K, 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 is postulated to have caused the star's outflows to form a bipolar structure (Gurzadyan 1997), similar to an hour-glass. This bipolar structure shows many interesting features seen in planetary nebulae such as ionisation walls, knots and sharp edges to the lobes.
