Image description: Located 15,000 light-years away in the constellation Sagitta, the Necklace Nebula is the glowing remains of an ordinary star.  It consists of a bright ring 12 trillion miles wide and is dotted with dense, bright knots of gas that resemble diamonds in a necklace. The Hubble telescope captured this image.
