NASA's Cassini spacecraft has captured never-before-seen views of Saturn from perspectives high above and below the planet's rings. The spacecraft has climbed to higher and higher inclinations, providing its cameras with glimpses of the planet and rings that have scientists gushing.
Scientists are celebrating the first Cassini spacecraft sighting of spokes, the ghostly radial markings discovered in Saturn's rings by NASA's Voyager spacecraft 25 years ago.
In a spectacular kick-off to its first season of prime ring viewing, which began last month, the Cassini spacecraft has confirmed earlier suspicions of an unseen moon hidden in a gap in Saturn's outer A ring. A new image and movie show the new moon and the waves it raises in the surrounding ring material.
With the latest Titan images showing channels and fluid-like branching, scientists have begun the debate anew whether fluid might have shaped the Earth-like moon. Imaging science team leader for Cassini, Carolyn Porco, describes the initial surprise and excitement of seeing Titan up close.
