LBN 468 and Gyulbudaghian’s Nebula

LBN 468 is a nebula 1,600 light years away from earth in the constellation Cepheus. One of the most interesting parts of the nebula is the bright part on the top left. This nebula is called Gyulbudaghian’s Nebula. This bipolar reflection nebula is generated by shock waves from a contracting protostar, PV Cephei. The nebula changes its shape and luminosity very fast, as illustrated below in the small animation.
