The Ghost Nebula, designated as Sh2-136, is located in the northern constellation Cepheus. It is a relatively dark and dusty region that requires long-exposure astrophotography to capture its ghostly apparitions properly.
What makes the Ghost Nebula Sh2-136 unique compared to other nebulae?
Sh2-136 is a striking reflection nebula that spans over 2 light-years across and is known for containing dark, creeping clouds of dust. It also features Bok globules, which are small, dense knots of cosmic dust where new stars are believed to be forming.
What other catalog names is the Ghost Nebula known by?
Aside from being listed as Sh2-136 in the Sharpless catalog, this same cosmic cloud is cataloged by astronomers as vdB 141 and CB230. These various designations refer to its classification in different stellar and nebular surveys.
What type of nebula is Sh2-136?
Sh2-136 is primarily classified as a reflection nebula, meaning it does not emit light of its own but instead reflects the light of nearby embedded stars. The surrounding dust scatters the starlight, creating the bluish and eerie grayish hues seen in deep space images.
