Cocoon Nebula

IC 5146 (also Caldwell 19, Sh 2-125, and the Cocoon Nebula) is a reflection/emission nebula in the constellation Cygnus. It is as a cluster of 9.5 mag stars involved in a bright and dark nebula. It is located near the star Pi Cygni, the open cluster NGC 7209, and the bright open cluster M39.

Cropped

The cluster is about 4,000 light yeas away, and the central star that lights it formed about 100,000 years ago, the nebula is about 12 arc minutes across, which is equivalent to a span of 15 light years. When viewing IC 5146, dark nebula Barnard 168 (B168) is an inseparable part of the experience, forming a dark lane that surrounds the cluster and projects westward forming the appearance of a trail behind the Cocoon.

The Lion Nebula

The Lion Nebula, also known as Sharpless 132 (Sh2-132), is a bright emission nebula located in the constellation Cepheus. It's a region of active star formation, characterized by the presence of young, hot stars that emit intense ultraviolet radiation. This radiation ionizes the surrounding hydrogen gas, causing it to glow in the characteristic red color of hydrogen-alpha emission.
