This 2011 view shows a plume of water ice particles and other material spewing from the moon's south pole via fractures in the ice, backdropped by Saturn's rings glowing brightly in the sunlight. The bright speck to the right of Enceladus is a distant star. The Cassini spacecraft took this image during its time at Saturn, which ended on Sept. 15, 2017. While the Cassini spacecraft is gone, an enormous collection of data about Saturn – the giant planet, its magnetosphere, rings and moons – will continue to yield new discoveries for decades to come.

Observing images of craters on Mars provides scientists insight into the water that carved them and the Red Planet's history of water activity.

What do you think this tadpole-shaped impact crater says about the water that used to fill it? Based on the terrain-height information and knowing that water always flows downhill, scientists were able to infer that the water in the tadpole crater was flowing down, and outward. The image was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on our Mars Reconnaissance Orbiter. Image credit: NASA/JPL-Caltech/Univ. of Arizona #nasa #space mars
