 PASADENA, Calif. (AP) - Scientists say they now believe rotating eddies are driving Saturn's jet stream winds, not the other way around.
The new view is based on images taken by the orbiting international Cassini spacecraft, which tracked the movement of cloud features on the ringed planet's southern hemisphere. Scientists initially believed eddies, or giant rotating storms, sapped energy out of the jets.
"Instead, what we find is that they are pumping energy into the jets," Cassini scientist Andrew Ingersoll of the California Institute of Technology said in a statement Tuesday.
