Saturn’s largest moon, Titan, has seas and lakes of liquid methane and ethane dotting its surface, but one question scientists have been trying to figure out is how the hollows in the ground, which hold the lakes, form to begin with. Now, a […]

Saturn is truly the “Lord of the Rings” and one of the most majestic places in the […]

Enceladus' Water Geysers May Be 'Curtain Eruptions' According to New Study

The water vapor jets on Enceladus are now thought to mostly be more like diffuse “curtains” rather than separate plumes. Image Credit: NASA/JPL-Caltech/SSI/PSI

The water vapor geysers on Saturn’s moon Enceladus are one of the most fascinating phenomena in the Solar System; the jets spray far out into space in a dazzling display unseen […]

NASA Actively Working to ‘Save Opportunity and LRO’ From Budget Cutters' Axe

Opportunity at Spirit of Saint Louis crater scanning into Marathon Valley and Endeavour crater from current location on Mars in April 2015 in this photo mosaic. The crater, featuring an odd mound of rocks, is the gateway to Marathon Valley and exposures of water altered clay minerals. This pancam camera photo mosaic was assembled […]

Thunderstorms are a powerful force of nature, but the ones we experience on Earth are dwarfed by the ones on the gas giant planet Saturn. They are huge and can be larger […]

Cassini Finds Evidence for Hydrothermal Activity on Saturn's Moon Enceladus
