  • Metals Needed for Life’s Origin
    Scientists have proposed a new potential catalyst for jump-starting metabolism, and life itself, on the early Earth. Transition metals like iron, copper and nickel along with small organic molecules could have catalyzed the synthesis of life's building blocks deep in the oceans around hydrothermal vents.

    Astronomers have measured the temperature of a young gas-giant planet and found that its atmosphere is unlike that of any previously studied extrasolar planet. Such observations help astrobiologists understand the properties of extrasolar planets and will aid in the search for habitable worlds beyond our
