LIVERMORE, Calif., Aug. 17 (UPI) -- U.S. researchers say tests on rocks from the lunar crust suggest the moon and Earth may be millions of years younger than previously thought.
While the most common estimate of the moon's age is 4.5 billion years, scientists at the Lawrence Livermore National Laboratory in California new measurements of isotopes of lead and neodymium in rocks gathered by the Apollo missions suggest it may be just 4.36 billion years old, a release issued by the laboratory Wednesday said.
