Cassini flies through Enceladus plumes

This happened yesterday, no report yet on what they found. For those unfamiliar with the Tiger Stripes, it's basically a 16 gigawatt power source (like, large enough to power Los Angeles) at the south pole of Saturn's moon Enceladus, where no such thing should be.
Meanwhile, I'm looking at this photo from December 2009. Several of you have already made the observation, but this particular photo kind of drives the point home. I'm not typically one to see random shapes in things and assume intelligent design, but, really this just doesn't seem like a naturally occurring thing.

Less than three weeks after its last visit to the Saturnian moon Enceladus, NASA’s Cassini spacecraft returns for an encore. At closest approach on April 14, the spacecraft will be just as low over the moon’s south polar region as it was on March 27 -- 46 miles, or 74 kilometers.

Like the last, this latest flyby is mainly designed for Cassini’s ion and neutral mass spectrometer, which will “taste” the particles in the curious jets spraying from the moon’s south polar region. Combined with the March 27 flyby and a similar flyby on Oct. 1, 2011, this close encounter will provide a sense of the jets’ three-dimensional structure and help determine how much they change over time.

On Cassini’s outbound leg, the spacecraft will pass by another Saturnian moon, Tethys, at a distance of about 6,000 miles (9,000 kilometers). The composite infrared spectrometer will look for patterns in Tethys’ thermal signature. Other instruments will study the moon’s composition and geology. The imaging cameras are expected to obtain new views of Enceladus and Tethys.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate in Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL.
