Saturn has been around the solar system for a while. But, of all the equinoxes it had since its formation, it was only this one that was observed directly with a probe right on the spot, the Cassini spacecraft. It revealed new and stunning images, which show new, previously unidentified quirks in the gas giant's rings, as well as shadows that were not observed until now. According to preliminary analyses of the photos the probe beamed back, Saturn's rings are not completely flat, as thought, but have bumps that are as high as the Rocky Mountains. Naturally, when compared to such a large planet and ring system, features that are only a few miles in height are not very impressive. However, they knocked off the theory holding that the formations were completely flat. “It's like putting on 3-D glasses and seeing the third dimension for the first time. This is among the most important events Cassini has shown us,†NASA Jet Propulsion Laboratory (JPL) Cassini project scient!
ist Bob Pappalardo, from Pasadena, California, says of the finds. The equinox took place on August 11th. Two equinoxes take place during every Saturnine orbit around the Sun, which takes about 29.7 Earth years.“The biggest surprise was to see so many places of vertical relief above and below ...
