Unreferenced date December 2007 Image Pistol star and nebula.jpg thumb right False color image of the Pistol Star and Pistol Nebula, taken by Near Infrared Camera and Multi Object Spectrometer NICMOS The Pistol Nebula surrounds one of the most massive stars known, the Pistol Star . Both are located 25,000 light years away from Earth, near the center of the Milky Way galaxy . The nebula contains approximately 10 solar mass es worth of ionized gas that was ejected by the star several thousand years ago. The nebula was named in the 1980s for its shape as seen in low resolution images that were available at the time. The pistol star, a luminous blue variable is 1.7 million times as bright as the Sun, and 120 200 times as massive.

This is an emission nebula showing glowing gas and darker dust lanes. The nebula is formed by Plasma physics plasma of ionized hydrogen and free electrons . The very brightest part of this nebula the knot at the right is separately classified as NGC 896 , because it was the first part of this nebula to be discovered. The nebula s intense red output and its configuration are driven by the radiation emanating from a small group of stars near the nebula s center. This open cluster of stars known as Melotte 15 contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun s mass. The cluster used to contain a microquasar that was expelled millions of years ago. gallery Image Melotte15HunterWilson.jpg Open Cluster Melotte 15 at the core of IC 1805.

McNeil s Nebula is a variable nebula discovered January 23, 2004 by Jay McNeil of Paducah , Kentucky . Overview Only recently discovered by amateur astronomer Julian W. McNeil II Jay McNeil , this peculiar looking object is currently classified as a cometary type reflection nebula . The newborn nebula was found while processing a wide field image of Orion constellation Orion s Messier 78 nebular region which was taken from McNeil s suburban backyard using a 3 inch refractor. Images taken of the area before September 2003 show absolutely no signs of the nebula nor its ruddy illuminating star, which can be seen near the object s southern apex. Preliminary research by Bo Reipurth Univ. of Hawaii reveals that the nebula was created when the deeply imbedded fetal star previously catalogued as IRAS 05436 0007 somehow erupted and went into outburst. The young star s sudden increase in brightness consequently resulted in the surrounding cocoon of gas and dust becoming illuminated much like a lighthouse would light up a foggy harbor. To actually capture such an eruption of a pre main sequence star so early in its evolution is an extremely rare occurrence. Often regarded as FU Orionis or EX Lupii type events, these sudden outbursts represent a very illusive stage through which most stars are thought to pass as they make final adjustments with their surroundings before settling down and becoming ...

The nebula has been identified on images taken by Evered Kreimer in October 1966, but not in various other images taken between 1951 and 1991.
