IC 417 (Spider Nebula)

IC 417 & NGC 1931
The Spider (IC 417) and Fly (NGC 1931) nebulae are situated in Auriga, at around 10 000 and 7000 light years away.
IC 417 was discovered on 25 September 1892 by the German astronomer Max Wolf. It is an emission and reflection nebula with an embedded star cluster, which is part of an extensive H-II nebula complex and star formation region in the Auriga constellation. The age is estimated to be less than 3 million years.
NGC 1931 was discovered by Wilhelm Herschel on 4 February 1793. It is a young star cluster, surrounded by a nebula of gas and dust and has partly amorphous, but partly also a filament-like structure. The dust nebula surrounds a small cluster of faint stars. It resembles a miniature version of the Orion Nebula and is located in a spiral arm of the Milky Way, which is probably an extension of the Perseus arm.
