There have been many incredible planetary missions over the past several decades, from as close as our Moon to the outer reaches of the Solar System. Right now, there are robotic explorers at Mars, Jupiter, Saturn, Ceres, and […]

Cassini Sends Back Spectacular New Images from First Ring-Grazing Orbit at Saturn

Saturn’s northern hemisphere up close: new image taken by Cassini on Dec. 3, 2016, showing small details in the turbulent atmosphere, including one corner of the “hexagon” with central cyclone. It was taken at a distance of about 240,000 miles (390,000 kilometers) from Saturn. Photo Credit: NASA/JPL-Caltech/Space Science Institute
