NGC 6302 (Bug Nebula) is a planetary nebula located 4,000 light years from the Earth in the constellation Scorpius.

The bright clusters and nebulae of planet Earth's night sky are often named for flowers or insects, and NGC 6302 is no exception. With an estimated surface temperature of about 250,000 degrees C, the central star of this particular planetary nebula is exceptionally hot though -- shining brightly in ultraviolet light but hidden from direct view by a dense torus of dust. This dramatically detailed close-up of the dying star's nebula was recorded by the newly upgraded Hubble Space Telescope. Cutting across a bright cavity of ionized gas, the dust torus surrounding the central star is near the center of this view, almost edge-on to the line-of-sight. Molecular hydrogen has been detected in the hot star's dusty cosmic shroud. NGC 6302 lies about 4,000 light-years away in the arachnologically correct constellation Scorpius.

The Butterfly Nebula is only thousands of years old. As a central star of a binary system aged, it threw off its outer envelopes of gas in a strong stellar wind. The remaining stellar core is so hot it ionizes the previously ejected gas, causing it to glow. The different colors of this planetary nebula are determined by small differences in its composition. This bipolar nebula will continue to shine brightly for only a few thousand more years, after which its central star will fade and become a white dwarf star. The above picture is one of the first ever taken by the Very Large Telescope (VLT), a new 8.2-meter telescope located in Chile.

This tiny nebula is very bright and does well in any filter. Also known as the Bug Nebula, it sits very close to SH2-8 part of which part of it can be seen in the upper left corner. A large telescope is needed to get detail and structure in this small nebula. The wider field of view system will pick up the surrounding nebula around the Bug Nebula.

This is NGC 6302, the Bug nebula, the remains of a dying G V class star. You can see an amazing Hubble image of this planetary nebula.
