Description

This beautiful multipolar planetary nebula is located in the southern sky in the constellation of Scorpius at a declination of -37 degrees. 

This magnitude 9.6 PN has many names and nicknames.  The names include NGC 6302, Sh2-6, Gum 60, RCW 124, and Caldwell 69.  The nicknames include the Butterfly Nebula, the Bipolar Nebula, and the Bug Nebula.

The PN is located almost 4,000 light years from earth. The butterfly's wingspan is over 3 light-years wide. It is relatively small in the sky at 3 minutes wide.

The butterfly shape is likely due to high speed gas outflow from the central star.  Several different axes of outflow can be seen.  A dark and dusty torus of gas is believed to be the "waist" around the central star, constricting its outflows.

The central star is a very hot white dwarf which is not visible here, nor was it visible in the early Hubble images.   Later Hubble images with the Wide Field Camera 3 revealed a faint central star.
