The Snake Nebula (also known as Barnard 72) is a dark nebula in the Ophiuchus constellation. It is a small but readily apparent SP-shaped dust lane that snakes out in front of the Milky Way star clouds from the north-north-west edge of the bowl of the Pipe Nebula. Its thickness runs between 2′ and 3′ and runs around 6′ in the north-west / south-east orientation. A good view in a 4" to 6" telescope requires clear dark skies.

Змея или Barnard 72 — тёмная туманность в созвездии Змееносца, открытая Эдвардом Барнардом в начале 20-го века. Представляет собой небольшой сгусток межзвёздной пыли, расположенной к северо-северо-востоку от туманности Курительной Трубки. Толщина туманности примерно от ≈2' до ≈3' по краям и ≈6' в середине. Является частью туманности Тёмного Коня.
