Latest Moons of Saturn Stories
Another glorious, backlit image of the planet Saturn has arrived from NASA's Cassini spacecraft, which has been in orbit around the planet for more than eight years.
The Cassini mission has spotted a miniature extraterrestrial version of the Nile River on Saturn's moon Titan. The find is the first time images have revealed a tier system this vast, and in such high resolution at any place other than Earth.
Scientists have long been intrigued by Titan because of the similarities it shares with Earth. Much like our planet, Titan has a seemingly layered structure, loosely similar to that of an onion.
While American folk singer Pete Seeger may not have considered Titan, the planet Saturn’s largest moon, as something unto which there is a season, it does seem that the moon has seen a type of turn or change in the seasons.
NASA announced on Monday its Cassini spacecraft has helped to discover a "video gamers' paradise" at Saturn.
A literal shot in the dark by imaging cameras on NASA's Cassini spacecraft has yielded an image of a visible glow from Titan, emanating not just from the top of Titan's atmosphere, but also - surprisingly - from deep in the atmosphere through the moon's haze.
NASA's Cassini spacecraft tracked the aftermath of a rare massive storm on Saturn, revealing disturbances in the planet's upper atmosphere long after the visible signs of the storm abated.
What resembles a giant hot cross bun? According to radar images from NASA's Cassini spacecraft, a mysterious, nearly circular feature on Saturn's moon Titan does.
As the Cassini spacecraft hurtles around Saturn along its continuing mission, NASA announced the fifteen-year anniversary of the probe’s launch this week.
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...
