Latest Moons of Saturn Stories
Researchers of the University of the Basque Country reveal some of the secrets of Saturn's mysterious hexagonal wave, including its rotation period, which could be that of the planet itself
Newly released images from NASA’s Cassini probe have revealed the “birthing” of a tiny moon in orbit around Saturn. The images, taken exactly one year ago on Tuesday, showed evidence of the formation of a tiny icy moon, named “Peggy”
WASHINGTON, April 14, 2014 /PRNewswire-USNewswire/ -- NASA's Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn that may be a new moon, and may
As NASA's Cassini mission approaches its 10th anniversary at Saturn, its team members back here on Earth are already looking ahead to an upcoming phase.
The Cassini spacecraft has discovered evidence of a large underground ocean of liquid water on one of Saturn’s moons, suggesting that the satellite could be home to extraterrestrial microbes.
WASHINGTON, April 3, 2014 /PRNewswire-USNewswire/ -- NASA's Cassini spacecraft and Deep Space Network have uncovered evidence Saturn's moon Enceladus harbors a large underground ocean of liquid
GREENBELT, Md., March 25, 2014 /PRNewswire-USNewswire/ -- NASA's Goddard Space Flight Center's Visitor Center in Greenbelt, Md., will host a free public event celebrating the science and exploration
To help mark 10 years in orbit, NASA's Jet Propulsion Laboratory in Pasadena, Calif., has created a special gallery on the Saturn website where members of the public can experience "15 minutes of frame" by submitting their own amateur images made up from image data brought back by Cassini.
On March 6, NASA’s Cassini spacecraft will swoop down within 933 miles (1,500 kilometers) of Titan to conduct its 100th flyby of the Saturn moon.
Just in time for the holiday season, NASA’s Cassini spacecraft has captured new images of Saturn and two of its moons – including Enceladus, a “white, glittering snowball of a moon.”
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...
