This raw image of the icy crust of Enceladus shows the ridges and valleys that cover the moon%u2019s surface. The grooves are typically a few hundred meters wide, but some rifts can be 125 miles long, up to 6 miles wide and more than half a mile deep.
Because grooved areas such as in the photo above often have no impact craters, they must be younger than 100 million years and suggest that active tectonics has formed the moon%u2019s crust, similar to the tectonic plate motion that shapes Earth%u2019s crust.
