Description

Sharpless 2-188 comprises a planetary nebula located in the constellation Cassiopeia. The expanding gas from the planetary nebula is colliding with ambient gas in the interstellar medium forming an ionisation front. The nebula is circular in shape but is much brighter to the southeast (lower left) because the central star is moving rapidly in that direction. Faint gas clouds can also be seen in the opposite direction.
