The Soap bubble nebula	Permalink

The Soap bubble nebula, or PN G75.5+1.7, is a planetary nebula in the constellation Cygnus, near the Crescent Nebula (NGC 6888). It was discovered by amateur astronomer Dave Jurasevich using an Astro-Physics 160 mm refractor telescope who imaged the nebula on June 19, 2007 and on July 6, 2008 Read more __________________

It looks like a soap bubble or perhaps even a camera fault, but the image at right is a newly discovered planetary nebula. Planetary nebulae, which got their name after being misidentified by early astronomers, are formed when an ageing star weighing up to eight times the mass of the sun ejects its outer layers as clouds of luminous gas. Most are elliptical, double-lobed or cigar-shaped, evolving after stars eject gas from each pole. Dave Jurasevich of the Mount Wilson Observatory in California spotted the "Cygnus Bubble" while recording images of the region on 6 July 2008. A few days later, amateur astronomers Mel Helm and Keith Quattrocchi also found it. Read more Position (2000): RA = 20h15m22s.2,Dec = +38d02'58" __________________
