Welcome to Saturn moon Enceladus...
7/1/09
Do underground oceans vent through the tiger stripes on Saturn's moon Enceladus?
Long features dubbed tiger stripes are known to be spewing ice from the moon's icy interior into space, creating a cloud of fine ice particles over the moon's South Pole and creating Saturn's mysterious E-ring. Evidence for this has come from the robot Cassini spacecraft now orbiting Saturn.
Pictured above, a high resolution image of Enceladus is shown from a close flyby. The unusual surface features dubbed tiger stripes are visible in false-color blue.
Why Enceladus is active remains a mystery, as the neighboring moon Mimas, approximately the same size, appears quite dead.
Most recently, an analysis of dust captured by Cassini found evidence for sodium as expected in a deep salty ocean.
Conversely however, recent Earth-based observations of ice ejected by Enceladus into Saturn's E-Ring showed no evidence of the expected sodium.
Such research is particularly interesting since such an ocean would be a candidate to contain life.
Have a wonderful day all!!!!
