description Bug Nebula Overview
The Bug Nebula, formally NGC 6302, is a bipolar planetary nebula located in the Scorpius constellation approximately 3,400 light-years from Earth. This notable object displays a distinctive twin lobe shape created by expanding gas ejected from a rapidly dying star. The central star within the nebula boasts exceptionally high temperatures, exceeding 200,000 Kelvin – one of the hottest known stellar cores. Astronomers and researchers studying stellar evolution and planetary nebulae find this object particularly valuable for observing extreme conditions in post-main sequence stars.
insights Why this score
Bug Nebula ranks #71 of 577 in the Nebula ranking, behind Christmas Tree Cluster Nebula, ahead of NGC 3576.
help Bug Nebula FAQ
Are the Bug Nebula and Butterfly Nebula the same object?
Yes. Both names refer to NGC 6302, which is also cataloged as Caldwell 69 in the constellation Scorpius.
What created the Bug Nebula's two wings?
A dying star expelled gas in opposing directions, producing two large lobes that span more than 3 light-years. A dense ring of dust around the center constrains the outflow and creates the nebula's pinched waist.
How hot is the star inside NGC 6302?
Estimates place the central star above 200,000 kelvins, making it one of the hottest known stars in the Milky Way. Its ultraviolet radiation ionizes the expelled gas and causes the nebula to glow.
Why was the Bug Nebula's central star difficult to observe?
A thick, doughnut-shaped dust structure obscures the star at visible wavelengths. Hubble observations reported in 2009 identified it directly, while later infrared work provided a clearer view through the dust.
