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. This color view of the Cocoon Nebula traces remarkably subtle features within and surrounding the dusty stellar nursery .
