Description

Just in time for the new year there is something creepy! :-) vdB 141 or the Ghost Nebula are part of CB 230 (or L1177) - a molecular cloud in the western part of the constellation Cepheus. It belongs to the "Cepheus Flare Region", a large complex of molecular clouds in the Milky Way. At its eastern edge, the cloud contains a globule with several infrared sources, which are protostars, as well as an associated jet. The designation CB 230 is derived from a 1988 catalogue by Dan P. Clemens and Richard Barvainis.

The globule is closely followed by a bright region of the molecular cloud, which contains a star that was catalogued as Reflection Nebula vdB 141 by Sidney van den Bergh in 1966 due to its nebulous appearance. Further west there are pillar-like structures whose appearance is reminding of ghosts. Because of these formations, the nebula is occasionally given names such as "Spooky Nebula", "The Ghosts of Cepheus" or similar.
