ASTRONOMY - IC 5146: The Cocoon Nebula

 2024 August 19

A red emission nebula is shown against a busy starfield 
with many dark dust filaments near the nebula's center. 
Near the bottom of the image is a smaller blue reflection 
nebula. 
Please see the explanation for more detailed information.

Explanation: Inside the Cocoon Nebula is a newly developing cluster of stars. Cataloged as IC 5146, the beautiful nebula is nearly 15 light-years wide. Soaring high in northern summer night skies, it's located some 4,000 light years away toward the constellation of the Swan (Cygnus). Like other star forming regions, it stands out in red, glowing, hydrogen gas excited by young, hot stars, and dust-reflected starlight at the edge of an otherwise invisible molecular cloud. In fact, the bright star found 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. A 48-hour long integration resulted in this exceptionally deep color view tracing tantalizing features within and surrounding the dusty stellar nursery.

Explanation: Inside the Cocoon Nebula is a newly developing cluster of stars. Cataloged as IC 5146, the beautiful nebula is nearly 15 light-years wide. Climbing high in northern summer night skies, it's located some 4,000 light years away toward the constellation Cygnus the Swan. Like other star forming regions, it stands out in red, glowing, hydrogen gas excited by young, hot stars, and dust-reflected starlight at the edge of an otherwise invisible molecular cloud. In fact, the bright star found 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. A 29 hour long integration with a small telescope from Ayr, Ontario, Canada resulted in this exceptionally deep color view tracing tantalizing features within and surrounding the dusty stellar nursery.
