IC 417 is an emission nebula and NGC 1931 is an open cluster involved in nebulosity. Together they have the common names of the Spider and the Fly. IC 417, the Spider, is located in the large complex of red hydrogen-alpha emission nebulosity on the right side of the image. NGC 1931, the Fly, is located in the smaller nebula at lower left in the image. Both are located in the constellation of Auriga at a distance of 7, 000 to 10, 000 light-years. Both nebulae have hot young stars in them that formed out of the gas and dust that comprise them. These stars then cause the nebulae to glow. In the case of the blue reflection nebula associated with NGC 1931, this is starlight reflected off of small dust particles. | |
