Explanation: How did this nebula get created? The Cocoon Nebula, cataloged as IC 5146, is
a strikingly beautiful nebula located about 4,000 light years away toward the constellation of
Cygnus. Inside the Cocoon is a newly developing open cluster of stars. Like other stellar
nurseries, the Cocoon Nebula is, at the same time, an emission nebula, a reflection nebula,
and an absorption nebula.
