1. Habitability of the Young Earth Could Boost the Chances of Life Elsewhere

    The conditions on the early Earth have long been a mystery, but researchers from NASA and the University of Washington have now devised a way to account for the uncertain variables of the time, in turn discovering that the conditions of early Earth may have been more moderate than previously thought.

    By applying these findings to other rocky planets, the researchers, whose results are published in the Proceedings of the National Academy of Sciences, conclude that the time-frame and likelihood of life persisting elsewhere is greater than first thought.
