WBIR-TVLarry Taylor, a distinguished professor in the Department of Earth and Planetary Sciences, talked with WBIR’s John Becker about his discovery that water on the moon originated from comets. Taylor discovered trace amounts of water on the moon. This discovery debunked beliefs held since the return of the first Apollo rocks that the moon was bone-dry. Then, he discovered water was actually pretty abundant and ubiquitous — enough so a human settlement on the moon is not unquestionable. Now, Taylor and a team of researchers have determined the lunar water may have originated from comets smashing into the moon soon after it formed.
