NGC 1555 (also catalogued as Ced 32B, DG 31, Bernes 84, Sh 2-238, Magakian 66, VdB 28), sometimes called Hind's Variable Nebula, is a variable nebula, illuminated by the star T Tauri, prototype of the class of T Tauri variable stars. It is a Herbig–Haro object. The edge of a molecular cloud, the star and the nebula vary significantly in brightness, but not at the same time, which adds some unanswered questions to the astronomers.The surroundings of Hind's nebula are embedded in layers of obscuring dust and gas. The distance to this area is estimated to be 400 light-years. Despite NGC 1555 is often imaged, there are only few images showing wider FOV of this region.
