Hind’s Variable Nebula (also known as NGC 1555, Sh2-238 or HH 155) is a variable nebula about 4 light-years across, located 400 light-years away at the edge of the Taurus Molecular Cloud in the Taurus.
A variable nebula is a reflection nebulae that changes in brightness because of changes in the star whose light it reflects. In this case the nebula is illuminated by T Tauri (the bright orange star in the image), which is one million year old variable star, ranging in magnitude from 8.5 to 13.5. This star is the prototype of the class of T Tauri variable stars, a class of young (less than a few million years old), Sun-like stars still in the early stages of formation. Contained with in the field is HH 155 a Herbig Haro object.
