NGC 6302 (also known as 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 seen in planetary nebulae.

2013年6月7日 · Though its wingspan covers over 3 light-years, NGC 6302 is no exception. With an estimated surface temperature of about 250,000 degrees C, the dying central star of this particular planetary nebula has become exceptionally hot, shining brightly in ultraviolet light but hidden from direct view by a dense torus of dust.

ngc 6302（也稱為臭蟲星雲或蝴蝶星雲）是在天蝎座的一個雙極的 行星狀星雲，距離地球約4000光年。 它是結構複雜的 行星狀星雲 ，NGC 6302的光譜顯示它的中心恆星是銀河系內最熱的天體之一，表面的溫度高達200,000K，暗示形成它的恆星一定也很大。

2009年9月9日 · Scientists have concluded the checkout period for NASA's Hubble Space Telescope and are now revealing images showcasing the power of the much-improved observatory. This is a pan sequence of the planetary nebula NGC 6302 (aka the Butterfly Nebula), located 3,800 light-years away,...

2022年11月21日 · Though its gaseous wingspan covers over 3 light-years and its estimated surface temperature exceeds 200,000 degrees C, the aging central star of NGC 6302, the featured planetary nebula, has become exceptionally hot, shining brightly in visible and ultraviolet light but hidden from direct view by a dense torus of dust.

2020年6月18日 · Hubble was recently retrained on NGC 6302, known as the "Butterfly Nebula," to observe it across a more complete spectrum of light, from near-ultraviolet to near-infrared, helping researchers better understand the mechanics at work in its technicolor "wings" of gas.

2020年6月18日 · This image from the NASA/ESA Hubble Space Telescope depicts NGC 6302, commonly known as the Butterfly Nebula. NGC 6302 lies within our Milky Way galaxy, roughly 3800 light-years away in the constellation of Scorpius.
