    ..Thus, we cannot confirm the reality of ancient oceans or water in active gullies but do see evidence of fluvial modification of geologically recent mid-latitude gullies and equatorial impact craters...

    Lunar and Planetary Laboratory, University of Arizona, Tucson, AZ 85721, USA
    Science 333:740-3. 2011
    ..Liquid brines near the surface might explain this activity, but the exact mechanism and source of water are not understood...

    Science 285:870-4. 1999
    ..A faint green glow appears concentrated on the night side of Io, possibly produced by atomic sodium. Io's disk-averaged emission diminishes with time after entering eclipse, whereas the localized blue glows brighten instead...

    W L Jaeger
    Astrogeology Team, U S Geological Survey, Flagstaff, AZ 86001, USA
    Science 317:1709-11. 2007
    ..Similar volcanic processes may have operated in other ostensibly fluvial channels, which could explain in part why the landers sent to investigate sites of ancient flooding on Mars have predominantly found lava at the surface instead...

    Astrogeology Team, United States Geological Survey USGS, Flagstaff, AZ 86001, USA
    Science 317:1711-5. 2007
    ..Repetition of particular layer types implies that quasi-periodic climate changes influenced the stratigraphic sequence in the polar layered deposits, informing models for recent climate variations on Mars...
