NASA develops process to create very accurate eclipse maps

New NASA research reveals a process to generate extremely accurate eclipse maps, which plot the predicted path of the moon's shadow as it crosses the face of Earth. Traditionally, eclipse calculations assume that all observers are at sea level on Earth and that the moon is a smooth sphere that is perfectly symmetrical around its center of mass. As such, these calculations do not take into account different elevations on Earth or the moon's cratered, uneven surface.
