Although Saturn's moon Tethys appears bland and neutral from space, it contains a number of features of interest. A large impact basin and an enormous trench are just two of the intriguing ...

Tethys is one of the larger of Saturn's 62 known moons. — -- NASA's Cassini spacecraft has spotted a huge impact basin on Tethys, one of Saturn's 62 known moons, shining brightly and spiking ...

On the moon’s eastern limb is the biggest scar of all, the crater Odysseus, which covers 18% of Tethys’s surface. On the far-larger Earth, that would be the equivalent of a crater the size of ...

This week, NASA released a stunning photo of Tethys, a large moon circling Saturn. But all people are talking about is how it looks like the Death Star.

Saturn's moon Tethys streaked with red 'arcs' that may be gone soon. Cassini has found enormous arcs of red material on the surface of Tethys, and astronomers can't explain what they are.

Saturn's icy moon Tethys hovers above the planet's iconic rings in a breathtaking photo by NASA's Cassini spacecraft. Though NASA released the image Monday (Aug. 21), Cassini actually captured it ...

Cassini has been orbiting Saturn since 2004. Over the last few years, Tethys' northern hemisphere has been experiencing its summer, allowing the sun to illuminate formerly dark areas of the moon's ...

New images taken from NASA's Cassini spacecraft appear to show unusual redish arcs marking the surface of the Saturn's icy moon Tethys. The strange features cover significant stretches of the moon ...

Visible in the early-morning sky today, Saturn’s two-toned moon Iapetus reaches superior conjunction just 1.4′ due south of Saturn. The proximity makes the now-11th-magnitude moon easier to find, as ...

While Tethys is 660 miles (1,062 kilometers) across, the crater Odysseus is 280 miles (450 kilometers) across, covering about 18 percent of the moon's surface area.

Tethys' orbit lies deep inside the magnetosphere of Saturn, which means that the plasma co-rotating with the planet strikes the trailing hemisphere of the moon.
