New comet could be source of Earth's water

Ocean water, long believed to have come from icy comets beyond Neptune, may have originated in asteroids found in warmer regions much closer to Earth, according to astronomers in Hawaii.

Two astronomers at the University of Hawaii found traces of water in an asteroid-like object floating in the solar system near Jupiter. It was a rare discovery in an area so close to the sun and, until know, believed to be orbited only by dry asteroids.
