Cocoon Nebula

Inside the Cocoon Nebula is a newly developing cluster of stars.
Cataloged as IC 5146, the beautiful nebula is nearly 15 light-years wide, located some 4,000 light years away toward the northern constellation Cygnus.
Like other star forming regions, it stands out in red, glowing, hydrogen gas excited by young, hot stars and blue, dust-reflected starlight at the edge of an otherwise invisible molecular cloud. In fact, the bright star near the center of this nebula is likely only a few hundred thousand years old, powering the nebular glow as it clears out a cavity in the molecular cloud's star forming dust and gas.

The color image seen here is based on data coming from several photographic plates taken between 1987 and 1991 by the Palomar Observatory's 48-inch (1.2-meter) Samuel Oschin Telescope as a part of the second National Geographic Palomar Observatory Sky Survey (POSS II). The images were recorded on two type of glass photographic plates - one sensitive to red light and the other to blue and later they were digitized.

The original file is about 17 Megapixels
with a resolution of about 1 arcsec per pixel.
The image shows an area of sky large 1,3
1,0 (for comparison, the full-Moon has a diameter of about 0,5).
The image is available for Museum, Planetariums, exhibitions, publishers and authors in very high-resolution. If interested in using the image, please read my policy and e-mail me with your request.
