IC 5146 (also Caldwell 19, Sh 2-125, Barnard 168, and the Cocoon Nebula) is a reflection [2] /emission [3] nebula and Caldwell object in the constellation Cygnus. The NGC description refers to IC 5146 as a cluster of 9.5 mag stars involved in a bright and dark nebula.

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 Cygnus the Swan.

The Cocoon Nebula in Cygnus is a reflection and emission nebula perfect for astrophotographers looking for a challenging object to image! Get tips and see our pictures of IC 5146 in this guide!

This image shows IC 5146, also known as the Cocoon Nebula. It is both a reflection and an emission nebula about 3300 light years away in the constellation of Cygnus. A reflection nebula reflects the light of nearby stars, while an emission nebula is formed when light from nearby stars ionizes the gas and makes the nebula glow.

The Cocoon Nebula (IC 5146) is located in a crowded field of stars spanning approximately 2 degrees. This interesting emission/reflection nebula resides within the constellation Cygnus, which rises high overhead to stargazers in mid-northern latitudes like myself.

Jan 16, 2025 · IC 5146 (also Caldwell 19, Sh 2-125, Barnard 168, and the Cocoon Nebula) is a reflection =10.5px / emission nebula and Caldwell object in the constellation Cygnus. The NGC description refers to IC 5146 as a cluster of 9.5 mag stars involved in a bright and dark nebula.

IC 5146 (also Caldwell 19, Sh 2-125, and the Cocoon Nebula) is a reflection/emission nebula and Caldwell object in the constellation Cygnus. The NGC description refers to IC 5146 as a cluster of 9.5 mag stars involved in a bright and dark nebula.

IC 5146 was discovered on 28 th July 1894 by the German astronomer Max Wolf. It is an open star cluster, involved in a large galactic nebula consisting of emission nebulae, reflection nebulae and dark nebulae. The designation IC 5146 applies to the star cluster including the nebula.

IC 5146 (also Caldwell 19, Sh 2-125, Barnard 168, and the Cocoon Nebula) is a reflection/emission nebula and Caldwell object in the constellation Cygnus. The cluster is about 4,000 ly away, and the central star that lights it formed about 100,000 years ago; the nebula is about 12 arcmins across, which is equivalent to a span of 15 light years.
