Latest Moons of Saturn Stories
Researchers report this week in the journal Geophysical Research Letters that NASA's Cassini spacecraft has detected oxygen on one of Saturn's moons.
A set of recent papers, many of which draw on data from NASA's Cassini spacecraft, reveal new details in the emerging picture of how Saturn's moon Titan shifts with the seasons and even throughout the day.
A new analysis of radar data from the Cassini mission has revealed regional variations among sand dunes on Saturn's moon Titan. The result gives new clues about the moon's climatic and geological history.
Researchers studying Saturn’s moon Titan have created a computer model of its atmosphere and methane cycle that, for the first time, explains how lakes and storms form and exist on the distant moon.
No team of reindeer, but radio signals flying clear across the solar system from NASA's Cassini spacecraft have delivered a holiday package of glorious images.
NASA's Cassini spacecraft successfully completed its closest-ever pass over Saturn's moon Dione on Monday, Dec. 12, slaloming its way through the Saturn system on its way to tomorrow's close flyby of Titan.
In an action-packed day and a half, NASA's Cassini spacecraft will be making its closest swoop over the surface of Saturn's moon Dione and scrutinizing the atmosphere of Titan, Saturn's largest moon.
The moon Enceladus, one of the jewels of the Saturn system, sparkles peculiarly bright in new images obtained by NASA's Cassini spacecraft.
New images and animated movies from NASA's Cassini spacecraft chronicle the birth and evolution of the colossal storm that ravaged the northern face of Saturn for nearly a year.
Saturn's moon Enceladus shows its icy face and famous plumes in raw, unprocessed images captured by NASA's Cassini spacecraft during its successful flyby on Nov. 6, 2011.
Lagrangian Point -- In Lagrangian mechanics, a Lagrangian point (or L-point) is one of five positions in space where the gravitational fields of two bodies of substantial but differing mass combine to form a point at which a third body of negligible mass would be stationary relative to the two bodies. Bodies at the L-point will not move relative to the parent bodies if they are not perturbed by other gravitational forces. They are sometimes also referred to as libration points. The...
Saturn's moon Phoebe -- Phoebe is the outermost of Saturn's known moons. Phoebe is almost 4 times more distant from Saturn than its nearest neighbor (Iapetus). It was discovered by William Henry Pickering in 1898. Most of Saturn's moons have very bright surfaces, but Phoebe's albedo is very low (.06), as dark as lampblack. All of Saturn's moons except for Phoebe and Iapetus orbit very nearly in the plane of Saturn's equator. Phoebe's orbit is retrograde, inclined almost 175, and is...
Saturn's moon Hyperion -- Hyperion is a moon of Saturn discovered by Bond and Lassell in 1848. It is the largest highly irregular (non-spherical) body in the solar system (Proteus is quite a bit larger but is almost spherical). It seems likely that Hyperion is a fragment of a larger body that was broken by a large impact in the distant past. The largest crater on its surface is approximately 120 kilometers in diameter and 10 kilometers deep. Like most of Saturn's moons, Hyperion's low...
Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...
Saturn's moon Rhea -- Rhea is the second largest moon of Saturn. It was discovered in 1672 by Giovanni Cassini. Rhea is an icy body with a density of about 1.24 gm/cm3. This low density indicates that it has a rocky core taking up less than one-third of the moon's mass with the rest composed of water-ice. Rhea's features resemble those of Dione, with dissimilar leading and trailing hemispheres, suggesting similar composition and histories. The temperature on Rhea is -174°C in direct...
