Description

IC417 & NGC 1931, commonly known as the Spider and Fly Nebula.  The Spider is about 10,000 light-years distant while the Fly is a bit closer to us at 7,000 light-years. They reside in the constellation Auriga.  Composed of clouds of gas and dust, this region is the site of new stellar birth.  The glowing nebula is caused by the excitation of the gas by clusters of massive, relatively newly formed, stars located near the centers of the nebulosity.  The large nebula on the right side of the image is the Spider and the small nebula is the Fly.
