These high resolution images of space scenes are matted to perfection on quality card-stock board and feature a description of the image on back.
Cassiopeia A is a supernova remnant in the constellation Cassiopeia and the brightest astronomical radio source in the sky. The supernova occurred approximately 11,000 light-years away in the Milky Way. The expanding cloud of material left over from the supernova is now approximately 10 light-years across. Despite its radio brilliance, however, it is extremely faint optically, and is only visible on long-exposure photographs.
