Sphere two poles is called the axis of rotation. Circles on the sphere that are parallel to the equator are lines of latitude. This terminology is also used for such approximately spheroidal astronomical bodies as the planet Earth (see geoid). Any plane that includes the center of a sphere divides it into two equal hemispheres. Any two intersecting planes that include the center of a sphere subdivide the sphere into four lunes or biangles, the vertices of which all coincide with the antipodal points lying on the line of intersection of the planes. The antipodal quotient of the sphere is the
Science On a Sphere May 4, 2006 the team unveiled "Footprints", the world's first fully realized spherical film. The project demonstrated a number of dramatic new techniques for visual conceptualization, including the idea of a seamless visual wrap. Since the release of "Footprints", several other movies have been made or are currently in production for SOS, including: Today there are over 80 narrated movies for SOS. Science On a Sphere Science On a Sphere (SOS) is a spherical projection system created by NOAA. It presents high-resolution video on a suspended globe rather than a flat screen, with the aim of better representing global phenomena.
