|2017-9-02: Cocoon Nebula/IC5146 ⬅︎|
| The Cocoon Nebula, also known as IC 5146, is a beautiful emission nebula and star cluster around 4,000 light years away in the constellation Cygnus, the Swan.
It is a stellar nursery -- a place where new stars are being born. It consists of bright red emission nebulas, blue reflection nebulas as well as dark absorption nebulas. Can you spot these different parts?
The massive central star provides the energy source for much of the emitted and reflected light.
Braden Henricksen produced this image by combining seventeen 105 second images for a total time of 30 minutes using the big telescope under the dome at Starry Hill with a Canon 6d camera. Nice job Braden!
