Weird Saturn Radio Signals Puzzle Astronomers
Saturn is sending astronomers mixed signals — radio signals, that is.
NASA's Cassini spacecraft recently found that the natural radio wave signals coming from the giant planet differ in the northern and southern hemispheres, a split that can affect how scientists measure the length of a Saturn day. But the weirdness doesn't stop there, researchers say.
The signal variations — which are controlled by the planet's rotation — also change dramatically over time, apparently in sync with the Saturnian seasons.
