The University of Colorado at Boulder in early 2007 will open a $180,000 exhibit featuring a floating sphere that can display animated images of Earth's atmosphere, oceans and continents, as well as other planets. Known as "Science on a Sphere," the exhibit will be located in CU-Boulder's Fiske Planetarium and will be open to the public, according to Douglas Duncan, director of the planetarium and the Sommers-Bausch Observatory.
