                        Exploration. What lies out there in the
                        distance? How did it all begin? In recent decades,
                        advances in space research have enabled scientists to
                        investigate these complex questions and answer some
                        simpler ones, such as where falling stars come from,
                        what causes a solar eclipse, and whether or not there is
                        life on Mars. As you explore this fascinating PC CD-ROM,
                        you will learn about the origin of the universe, the
                        development of galaxies, the birth and death of stars,
                        plus much, much, more. Contains written text, narration,
                        photographs, sounds, animated sequences, and full-screen
                        video segments about the universe, the bodies in it,
                        tools used in studying them, and the highlights of
                        astronomical research past and present. (Originally released
                        as Touch the Sky, Touch the Universe). |  |
