NGC 1555, also known as Hind's Variable Nebula, is a variable nebula,
illuminated by the young star T Tauri, located in the constellation Taurus.
It is a Herbig–Haro object. Herbig–Haro (HH) objects are small patches of nebulosity associated with newly born stars, and are formed when narrow jets of partially ionized gas ejected by those stars collide with nearby clouds of gas and dust at speeds of several hundred kilometres per second. HH objects are transient phenomena that last less than a few thousand years. They can evolve visibly over quite short astronomical timescales as they move rapidly away from their parent star into the gas clouds of interstellar space. Besides NGC 1555 also six other HH objects are visible in the above image of this dusty region:
