VDB 1, VDB 1d (LBN 578) - Reflection Nebulae in Cassiopeia

VdB 1 is a Reflection Nebula in Cassiopeia in about 1600 light-years distant. It spans 5 light-years across. To the north east of vdB 1 are situated two interesting nebulae associated with young variable stars and the process of star formation. These are catalogued as Herbig-Haro objects: V633 Cas (HH164) and V376 Cas (HH162). Herbig-Haro objects are typically seen along the rotational axis of the star, and are a relatively brief cosmic light show, they only last a few thousand years.The long spike from above belongs to the bright star Caph (Beta Cassiopeiae).
