Cygnus Nebulosities
Looking toward the constellation Cygnus [ ], a stunning and complex region of nebulae strewn along the plane of our Milky Way [ ] galaxy is revealed in this unique wide-angle [ ] sky view. Recorded with a filter designed to transmit light emitted by [ absorption.html ] hydrogen atoms, the image emphasizes [ ] cosmic gas clouds in a 34 by 23 degree field centered on the well known Northern Cross asterism. Bright, hot, supergiant star Deneb [ ] (the top of the cross) and popular celestial sights such as the North America [ ] and Pelican [ ] emission regions, the IC 1318 "butterfly [ ]", and the Crescent [ ] and Veil nebulae [ ] can be identified by placing your cursor over the image. Silhouetted by the glowing interstellar [ ] clouds and crowded star fields, the dark Northern Coal Sack is also visible, part of a series of obscuring dust clouds forming the Great Rift in the Milky Way [ ]. These Cygnus nebulosities are all located about 2,000 light-years away. Along with the Sun, they lie within the Orion spiral arm [ ] of our galaxy.
