Mars's Dramatic Climate Variations are Driven by the Sun

  On Mars’s poles there are ice caps of ice and dust with layers that reflect to past climate variations on Mars. Researchers from the Niels Bohr Institute have related the layers in the ice cap on Mars’s north pole to variations in solar insolation on Mars, thus established the first dated climate history for [continue reading]
