This is a picture taken by NASA with the Hubble telescope in 2003. They are referring to it as the "Eye of God". What it actually depicts is the so-called Helix Nebula, described by astronomers as "a trillion-mile-long tunnel of glowing gases." At its center is dying star which has ejected masses of dust and gas to form tentacle-like filaments stretching toward an outer rim composed of the same material. [NASA]
