Fresh Tiger Stripes on Saturn's Enceladus

The tiger stripes on Saturn's moon Enceladus might be active.

Even today, they
may 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.

Recent evidence for this has come from the
robot Cassini spacecraft now orbiting

Cassini detected a marked increase in particle collisions
during its July flyby only 270 kilometers over a South Polar region of

Pictured above,
a high resolution image of Enceladus is shown from the close flyby.

The unusual surface features dubbed
tiger stripes are visible on the left in false-color blue.

Enceladus is active remains a mystery, as the neighboring moon
approximately the same size, appears
quite dead.
