NGC 3199 [2] [1] [3] is an emission nebula in the constellation Carina. It is commonly known as the Banana Nebula. [4] The object was discovered in 1826 by the Scottish astronomer James Dunlop. [5] It was thought to be the bow shock around the central star, WR 18, an especially hot and luminous Wolf–Rayet star; however, it was determined that the nebula formed due to the composition of local space, not because of the star's movement.
