Saturn’s moon Titan is known for its methane seas, lakes, and rivers; surprisingly Earth-like in appearance yet distinctly alien at the same time. But there is also evidence for another ocean, this one of water, below the surface. Little is known about this hidden watery world, but now new results suggest it is likely very salty – as much as the Dead Sea on Earth.

Titan is a complex world, reminiscent of our own planet in many ways, with mountains, seas, lakes, rivers and rain. Albeit the liquid on this super-cold moon is methane/ethane instead of water, but the visual similarities are striking. Just how geologically active Titan might be in other ways however isn’t really known yet, but a new discovery might provide some clues. What looks like a new small “island“ has appeared in one of the hydrocarbon seas, where it wasn’t before. Is it really an island, or something else?
Saturn’s moon Titan is one of the murkiest places in the Solar System; its thick smog-like hydrocarbon haze in the upper atmosphere shrouds the entire moon, much like Venus’ perpetual cloud cover. Titan’s surface is completely hidden by this orange-ish haze, making it look rather bland and uninteresting. This unique environment may provide valuable clues to the nature of atmospheres on distant exoplanets, however, according to new findings from scientists with the Cassini mission.
The Cassini spacecraft has taken thousands of images of Saturn and its moons, and this one is another beauty. Titan, Saturn’s largest moon, and the one with the methane rain, rivers and lakes, floats in space out beyond Saturn’s rings.
This is a beautiful montage showing sunlight reflecting off lakes on two different worlds. A water lake (of course) on Earth and a methane lake on Saturn’s moon Titan. While the composition is quite different, the hydrological and methanological processes are remarkably similar, with rain, rivers, lakes and seas. Familiar but alien at the same time… Thanks to Planetary Landscapes for use of this image!
Apart from being composed of liquid methane instead of water, the rivers, lakes and seas of Saturn’s moon Titan are amazingly similar in appearance to those on Earth. The hydrological cycle is also very similar, with Titanian rain replenishing them.
Want to go river rafting on Titan? The largest moon of Saturn is the only other place in the solar system known to have rivers, lakes and seas on its surface. Appearance-wise, they are eerily similar to their earthly counterparts, but are composed of liquid methane instead of water, in Titan’s extremely cold environment. Now, the Cassini spacecraft has found the largest Titanian river system yet, similar to the Nile River on Earth, as announced on December 12, 2012.
With its methane lakes, rivers and rain, Titan is already one of the most fascinating worlds in our solar system, with intriguing parallels to Earth despite the much colder climate.
Saturn’s largest moon, Titan, is in many ways one of the most Earth-like places in the solar system. More like a planet than most moons, it is the only other world, so far anyway, known to have lakes on its surface. Similar to the hydrological cycle on Earth, the lakes are filled by rain, which also creates rivers and streams. Titan, however, is much colder than Earth, so the liquid is methane / ethane, not water.
This discovery has made Titan one of the most fascinating destinations for further exploration. The Cassini spacecraft has increased our knowledge many-fold, but there is only so much that can be done from orbit. But now a new mission proposal may change that, one which would actually send a boat to land in one of the lakes in the northern hemisphere.
