Exotic instruments ranging from an array of mirror telescopes mounted in a rotating building high above the Arizona desert, to x-ray images from orbiting telescopes in space, allow Smithsonian astrophysicists Margaret Geller and John Huchra to painstakingly pinpoint galaxies as much as 300 million light years across time and space from the Earth. In the process, Geller and Huchra have discovered a remarkable structure to the arrangement of galaxies: they are arranged as though on the surface of great "soap bubbles," separated by vast areas of other mysterious phenomena: dark matter. Producers Wes Horner and Ann Finkbeiner present a virtual adventure through space and time.
