Science On a Sphere® (SOS) is a room sized, global display system that uses computers and video projectors to display planetary data onto a six foot diameter sphere, analogous to a giant animated globe.  Science On a Sphere extends NOAA's educational program goals, which are designed to increase public understanding of the environment. Using NOAA's collective experience and knowledge of the Earth's land, oceans, and atmosphere, NOAA uses Science On a Sphere as an instrument to enhance informal educational programs in science centers, universities, and museums across the country. Science On a Sphere has the added capability of displaying astronomical datasets as well, past and present, bringing the world of Galileo and our current understanding of the Universe to life.
