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. The cluster is also known as Collinder 470. [4]

The Ring Nebula (also catalogued as Messier 57, M57 and NGC 6720) is a planetary nebula in the northern constellation of Lyra. [4] C] Such a nebula is formed when a star, during the last stages of its evolution before becoming a white dwarf , expels a vast luminous envelope of ionized gas into the surrounding interstellar space .
In mid 2016, a large addon pack project called Celestia Origin was created, which replaces all vanilla textures and graphics with higher-quality renderings, adds more minor objects such as TNOs and asteroids, while also adding more extrasolar planets with custom textures, more nebulae with full 3D and accurate models, more stars and galaxies ...
NGC 6326, a planetary nebula with glowing wisps of outpouring gas that are lit up by a binary [3] central star. A planetary nebula is a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives. [4] The term "planetary nebula" is a misnomer because they are unrelated to ...
