Explanation: Do underground oceans vent through the tiger stripes on Saturn's moon Enceladus? Long features dubbed tiger stripes are known to bespewing ice from the moon's icy interior into space,creating a cloud of fine ice particles over the moon's South Poleand creating Saturn's mysterious E-ring. Evidence for this has come from therobot 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 dubbedtiger stripes are visible in false-color blue. WhyEnceladus is active remains a mystery, as the neighboring moonMimas,approximately the same size, appearsquite 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.<\/p>\n
