Dark Wolf Nebula B 228

Barnard 228 (B 228), widely known as the Dark Wolf Nebula, is a dense interstellar cloud of dust and gas located in the southern constellation Lupus. Situated roughly 500 light-years from Earth, it is part of the Lupus Molecular Cloud and acts as a stellar nursery, with the nebula's dense, cold dust absorbing visible light to create a striking dark, wolf-like silhouette against the luminous Milky Way background.
