Today marks the annual celebration of Earth Day that started in 1970. Here's an interesting look at our planet: aerials taken by GeoEye satellites. Headquartered in Dulles, Va., GeoEye is commissioned by various defense, intelligence, urban planning and environmental monitoring groups to keep an eye on Earthly developments.
