Fresh Tiger Stripes on Saturn's Enceladus
Explanation: 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 that orbited
Saturn from 2004 to 2017.
Pictured here, 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. A
recent analysis of
ejected ice grains has yielded evidence that complex organic molecules exist inside Enceladus. These large carbon-rich
molecules bolster -- but do not prove -- that oceans under Enceladus' surface could
contain life.
