The Rotten Fish Nebula
Located in the constellation Cepheus, LDN 1251 is a molecular cloud that consists of dark structures, faintly glowing or reflecting dust and gas. It is commonly known as the Rotten Fish Nebula, and its designation "LDN" comes from Lynd's Catalogue of Dark Nebulae. LDN 1251 is relatively close to our solar system, at around 1,000 light years away, and is part of a larger complex of dark nebulae in this area of the sky. Additionally, there are lots of intresting galaxies visible in the background and numerous Herbig-Haro objects that are associated with LDN 1251. They can be seen as small patches of nebulosity within the dark nebula and are linked to newly forming stars.
