The Twin Jet Nebula (PN M2-9) is a striking example of a bipolar planetary nebula. Bipolar planetary nebulae are formed when the central object is not a single star but a binary system. Studies have shown that the nebula’s size increases with time, and measurements of this rate of increase suggest that the stellar outburst that formed the lobes occurred just 1,200 years ago.

The Butterfly Nebula - NGC 6302 (also called the Bug Nebula, Butterfly Nebula, or Caldwell 69) is a bipolar planetary nebula in the constellation Scorpius. The structure in the nebula is among the most complex ever observed in planetary nebulae. The spectrum of NGC 6302 shows that its central star is one of the hottest stars 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.
