The Helping Hand Nebula is a very faint dust cloud in the Cassiopeia constellation. The primary target is the central dust cloud in the shape of a right hand/arm, extended as if to give or offer help.
The dust cloud is comprised of 3 dark nebulae, catalogued as objects of Lynd’s Dark Nebulae (LDN): LDN 1357 makes up the fingers, LDN 1355 makes up the palm of the hand, and LDN 1358 is the shoulder of the extended arm.
Below the hand is the reflection nebula, vdB 9, a dust cloud reflecting the bluish light of SU Cassiopeiae. SU Cas is a Cepheid variable, a type of star which allows us to accurately measure cosmic distances in our galaxy and beyond. SU Cas is 1540 light years away from Earth.
