  • Decoding early Martian weather: Analyzing carbonate minerals in meteorite Allan Hills 84001

    Updated: 2011-10-24 06:20:01
    (PhysOrg.com) -- While geological evidence points to the presence of liquid water on Mars during the Noachian epoch (the period from 4.5 to 3.5 billion years ago), determining the temperature of that water – a factor critical to the probability of its ability to support early life – has hitherto been impossible. Recently, however, researchers at California Institute of Technology Geological and Planetary Sciences have derived a precipitation temperature of 18 °C from carbonate minerals found in the 4.1 billion-year-old Allan Hills 84001 (ALH84001) meteorite. Although this ancient aquifer’s temperature was relatively mild, the researchers note that their findings do not necessarily demonstrate habitability.

    After meticulously stitching together images that were gathered over six years by a NASA spacecraft in orbit around Saturn, astronomers have created a global map of the surface of Titan, the ringed planet’s largest moon, and it features some surprisingly Earth-like geological features. An international team of astronomers, led by the University of Nantes in France, created the striking mosaic of ...
