Find a giant soap bubble "floating in space

Sounds like a soap bubble, or even may seem a failure of the camera, but the image is a planetary nebula discovered recently. Planetary nebulae, which received a wrong name to have been poorly identified by astronomers, are formed when an aging star with a mass of up to eight times the mass of the Sun, ejecting their outer layers and creates clouds of luminous gas. Most are elliptical, with two lobes or in a cigar, then move that the stars eject gas from each of its poles Dave Jurasevich, Mount Wilson Observatory in California, discovered the "Bubble Film" ( "Cygnus Bubble ") during a search of images of the region, July 6, 2008. A few days later, the amateur astronomers and Mel Helm Keith Quattrocchi also found. The bubble, which was officially named last week as G75.5 PN 1, 7, has been there long ago. A more detailed observation of images of the second recognition of the Palomar Sky (Palomar Sky Survey) shows that had the same size and brightness for 16 years. Jurasevich think is overlooked because it is very weak. "It is a beautiful example," said Adam Frank, University of Rochester, New York. "The areas are very rare." One explanation is that we are looking at the image of a typical circular cylindrical nebula. However, it remains very symmetrical, says Frank.
