Saturn’s largest moon, Titan, is a very alien yet eerily Earth-like world, with rain, rivers, lakes, and seas; seen from above, the landscape has a familiar look to it. But those lakes, seas, and rivers are fed by a different kind of rainfall – liquid methane/ethane. It is far too cold on the surface for liquid water, but the liquid hydrocarbons nicely fill in for H20 in Titan’s “water cycle.” Now, a new study shows how this rainfall interacts with and changes underground aquifers.

A recent discovery by scientists may have implications for possible extraterrestrial life: Bacteria have been found thriving in a lake of oil in Trinidad, again showing how life can exist in even the most inhospitable conditions on Earth. The discovery brings to mind the similar environment on Saturn’s moon Titan, where lakes and seas of liquid hydrocarbons (methane/ethane) exist at the moon’s poles.
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.
