Lunar rock analysis suggests Earth 'born' with water, rather than delivered by asteroid - UPI.com

Feb. 17 (UPI) -- Earth either started off with water or was hit by something that brought it here, and scientists now say that it's most likely the planet was "born" with the key to life.

Researchers at the Lawrence Livermore National Laboratory came to this conclusion by analyzing the isotopic make up of lunar rocks, according to the new study, published Thursday in journal PNAS.
