Photo of the Day If you could stand on Titan -- what would you see? The featured color view from Titan gazes across an unfamiliar and distant landscape on Saturn's largest moon. The scene was recorded by ESA's Huygens probe in 2005 after a 2.5-hour descent through a thick atmosphere of nitrogen laced with [...]
NASA/JPL-Caltech/Space Science Institute Dramatic plumes, both large and small, spray water ice out from many locations along the famed tiger stripes near the south pole of Saturn’s moon Enceladus in this image released on Feb. 23, 2010. A study published in October 2025 analyzed data from NASA’s Cassini mission and found evidence of previously undetected [...]
