Cocoon Nebula Deep Field
Explanation: Inside the Cocoon Nebula is a newly developing cluster of stars. The cosmic Cocoon on the upper right also punctuates a long trail of obscuring
interstellar dust clouds to its left. Cataloged as
IC 5146, the beautiful nebula is nearly 15 light-years wide, located some 3,300 light years away toward the northern constellation of the Swan (
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 a nearly 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 slowly
clears out a cavity in the
molecular cloud's star forming dust and gas. This
exceptionally deep color view of the Cocoon Nebula traces tantalizing features within and surrounding the dusty
stellar nursery.
