Even though Saturn’s rings appear clean and young, they may be as old as the planet itself according to international researchers. It was previously thought that impacts with small rocky debris travelling through space – called micrometeoroids – would dirty and darken the rings over time, but in 2004 the Cassini spacecraft revealed the rings to be clean and bright suggesting that they are not very old.

New analysis of marsquakes, which are similar to earthquakes, could offer clues into how Mars has evolved over billions of years, according to new research from The Australian National University and the Chinese Academy of Sciences.

The Voyager 2 flyby of Uranus in 1986 may have occurred during a rare intense wind event, according to international researchers who say this means our scientific understanding of the planet may be flawed.
