    In the 1950s, Stanley Miller demonstrated that organic compounds could form under conditions mimicking the primordial Earth. By re-examining some of Miller's unused samples with modern techniques, scientists have found that volcanoes and sulfur may have been important in life's origin on our planet.

    Springtime on Titan has brought methane rain to the moon's equatorial deserts. Observations suggest that recent weather on Titan is similar to that over Earth´s tropics, only based on methane cycles rather than liquid water. Understanding Titan's weather is an important step in determining the moon's
