Description

Gyulbudaghian's variable Nebula is a bipolar reflection nebula. It is similar to the famous Hubble's Variable Nebula (NGC 2261, Monoceros). The nebula, that changes its shape and luminosity too, discovered by Armen Gyulbudaghian Armenian astronomer in 1977. This nebula is generated by shock waves from a contracting protostar, PV cephei. The bipolar structure is barely visible at the left side of PV cep, it is shaded by the dark dust clouds.
