Sh2-234 - IC417 - THE SPIDER

IC 417 (also known as Sh2-234) is an emission nebula of almost 100 light-years across, located some 10,000 light-years away from Earth in the constellation of Auriga (the Charioteer). It is often referred to as the Spider Nebula and in that case its prey is a nearby emission nebula called the Fly (NGC 1931). The nebula contains a young open cluster of about 40 stars, and is energized by its hot, massive blue stars which are still embedded in glowing hydrogen gas. The bluish clouds of gas at the top of the image are locations of new star formation.
