In fact, the distant world reflects over 90 percent of the sunlight it receives, giving its surface about the same reflectivity as fresh snow. A mere 500 kilometers in diameter, Enceladus is a surprisingly active moon. Data and images collected during Cassini’s flybys have revealed water vapor and ice grains spewing from south polar geysers and evidence of an ocean of liquid water hidden beneath…

The gas giant’s ring plane tilts from most open in 2018 to approaching edge-on in 2023 (top to bottom). That’s summer to nearly the autumn equinox for Saturn’s northern hemisphere. In the sharp planetary portraits, Saturn’s northern hexagon and a large storm system…
