Cocoon Nebula

This is IC5146, popularly known as the Cocoon Nebula with the brownish molecular nebula Barnard 168 stretching westward in the sky from the Cocoon. The Cocoon's reddish hue is caused by radiation from the nebula's central star, a 100000 year-old star approximately 4000 light years away from us. The diameter of the Cocoon is about 15 light years across.
