More than 100 UFO's have been seen along the India-China border since August. Mysterious yellow spheres of light have been appearing on the Chinese side of the border and move across the sky for three to five hours before disappearing. Scientists were able to photograph and study the objects, but have not been able to pick them up on radar. As result, experts have been able to determine that they are non-metallic and are not unmanned aerial vehicles, meteors or planets. Even though scientists aren't sure what these UFOs are, they're not ready to consider them visitors from another planet, saying that there is no evidence that they are of extraterrestrial origin.
