Latest Tethys Stories
NASA announced on Monday its Cassini spacecraft has helped to discover a "video gamers' paradise" at Saturn.
NASA's Cassini spacecraft made its closest approach to Saturn's tiny moon Methone as part of a trajectory that will take it on a close flyby of another of Saturn's moons, Titan.
These raw, unprocessed images of Saturn's moons Enceladus and Tethys were taken on April 14, 2012, by NASA's Cassini spacecraft.
Over the past decade, the undersea robots known as autonomous underwater vehicles (AUVs) have become increasingly important in oceanographic research.
Scientists using data from NASA's Cassini spacecraft have learned that distinctive, colorful bands and splotches embellish the surfaces of Saturn's inner, mid-size moons.
NASA's Cassini spacecraft has returned Saturnian moon images from its flyby late last week, revealing light and dark contrasts worthy of chiaroscuro painters like Caravaggio.
NASA says its Cassini spacecraft's magnetospheric imaging instrument has detected a new, temporary radiation belt around the orbit of one of Saturn's moons. Scientists located the new radiation belt in the orbit of the moon Dione, about 234,000 miles from the center of the planet. The new belt, which has been named the Dione belt, was detected by the instrument for only a few weeks on three separate occasions in 2005, the space agency said in a statement.
Scientists using the Cassini spacecraft's Magnetospheric Imaging instrument (MIMI) have detected a new, temporary radiation belt at Saturn, located around the orbit of its moon Dione at about 377 000 km from the center of the planet.
Something is about to happen on Saturn that's so pretty, even Hubble will pause to take a look.
Saturn's moon Calypso -- Calypso is a moon of Saturn discovered by Pascu, Seidelmann, Baum and Currie in 1980 from ground-based observations. Calypso is co-orbital with the moon Tethys, and resides in Tethys' trailing Lagrangian point (L5). The moon Telesto resides in Tethys' leading Lagrangian point. ----- Orbital radius: 294,660 km Diameter: 26 km (34 x 22 x 22) Mass: Unknown Orbital period: 1.8878 days Orbital inclination: 0 ----- NASA Learn more on this...
Telesto is a small Trojan moon of the sixth planet from the sun, Saturn. Telesto, which was discovered in 1980 by Smith, Reitsema, Larson and Fountain, is one of around 200 natural satellites in Saturnian orbit. It is one of only 62 moons that have a secure orbit, and only one of 53 named moons orbiting the ringed planet. Telesto was officially designated S/1980 S 13 and was officially named in 1983 after the Greek sea goddess of the same name. This moon is also designated as Saturn XIII...
Saturn's moon Tethys -- Tethys is a moon of Saturn that was discovered by Giovanni Cassini in 1684. Tethys is an icy body similar in nature to Dione and Rhea. The density of Tethys is 1.21 g/cm3, indicating that it is composed almost entirely of water-ice. Tethys's surface is heavily cratered and contains numerous cracks caused by faults in the ice. There are two different types of terrain found on Tethys, one composed of densely cratered regions and the other consisting of a dark...
Saturn's moon Mimas -- Mimas is a moon of Saturn that was discovered in 1789 by William Herschel. Mimas' low density (1.17) indicates that it is composed mostly of water ice with only a small amount of rock. Mimas' most distinctive feature is a colossal impact crater 130 km across, named Herschel after the moon's discoverer. Herschel covers almost 1/3 of the diameter of the entire moon; its walls are approximately 5 km high, parts of its floor measure 10 km deep, and its central peak...
