Comment: |
Cocoon nebula is a star forming area. A young open cluster of about 80 stars is developing inside the nebula. The Cocoon is molecular cloud with pinkish emission areas, bluish reflection areas and dark absorption nebulous areas. Their combination creates striking colors and appearance of the Cocoon. Massive star visible in the center of the nebula is responsible for much of the light emitted and reflected in that area. It has cleared material in the middle of the nebula, so we can take a look at the stars forming inside. IC5146 is some 4000 ly distant. |
