Saturn
New analysis of Cassini spacecraft data reveals that particles from Saturn's rings extend hundreds of thousands of kilometers above and below the planet, forming a giant dusty doughnut. Scientists suggest micrometeorite impacts vaporize ring material, propelling it to these heights. This discovery challenges previous views of the rings as merely thin discs.

New simulations using supercomputers have shown that Enceladus, a moon of Saturn, loses 20 to 40 percent less mass from its icy plumes than previously estimated. Researchers at the University of Texas at Austin analyzed data from NASA's Cassini mission to model the plumes' behavior. These findings could inform future missions probing the moon's subsurface ocean for signs of life.
