BEYOND STAR CHARTS
Many planetarium programs go far beyond star-charting functions. For example, they may simulate flights around the Solar System, showing the sky from other planets. Some contain still images and movies of planets and deep-sky objects, or evenj allow you to create animated movies of celestial events.
Multimedia programs available on CD-ROM are like electronic, interactive books. You can tour the planets or fly over a landscape on Venus or Mars. Such programs are an excellent way to get your family and friends interested in astronomy.
