Jupiter Moons Callisto and Io in S106 Cignus by Interanimate

Direct cut from an HD image of the S106 nebula in Cignus. An image of S106 at http://apod.nasa.gov/apod/ap111107.html is thought by many to look like a soaring, celestial snow angel. Superimposed over the cut are two Jupiter moons Callisto and Io.
