Photos: Saturn moon wears 'tiger stripes'
The Cassini orbiter had a recent encounter with Saturn's moon Enceladus which is 505 kilometers (314 miles) across, and small enough to fit within the length of the United Kingdom, as illustrated here. The intriguing icy moon also could fit comfortably within the states of Arizona or Colorado.
At the south pole of Enceladus, the Cassini orbiter (route in yellow) found fractures in the surface resembling "tiger stripes" (circled in red). The tiger stripes turned out to be the source of water vapor and a stream of fine, powder-sized icy particles coming from the surface. The particles reached an altitude of 460 kilometers (286 miles).
