The unmanned Cassini spacecraft, after completing two passes in the vast, unexplored area between Saturn’s rings has discovered not much else there, researchers at NASA said. Scientists have been surprised to find that not all that much—not even space dust—lies between Saturn’s iconic rings.
“The region between the rings and Saturn is ‘the big empty,’ apparently,” said Cassini Project Manager Earl Maize of NASA’s Jet Propulsion Laboratory in Pasadena, California, after the probe’s first pass.
The rings themselves are made of fast-moving particles of ice and space debris.
