Barnard 5 (B5) is a dark nebula located in the constellation Ophiuchus. It is part of the Barnard catalog, a collection of dark nebulae compiled by astronomer Edward Emerson Barnard in the early 20th century. Dark nebulae like Barnard 5 are regions of space that contain a high concentration of dust and gas, which makes them appear opaque against the backdrop of bright stars and other celestial objects.
