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蓬aro object.
Herbig蓬aro (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:
HH 255 (=Burnham's Nebula)
HH 355A
HH 355B
HH 355D
HH 355E
HH 355F
