The Cassini spacecraft continues to make new discoveries about Titan’s methane seas and lakes, answering some questions but raising additional ones as well. As announced this week, Cassini has discovered two more of the unusual “magic islands” – bright features which seem to appear in the seas where they didn’t exist before – and has measured the depth of the largest Titanian sea.

Saturn’s moon Titan is a very unique world, and the only place in the solar system known to have seas and lakes (liquid methane/ethane) on its surface, other than Earth. And just like our home world, if you look at them at the right moment from space, you can see sunlight gleaming off of them, as the Cassini spacecraft just did again on Aug. 21, 2014.
Titan is the only moon in the solar system known to have a dense atmosphere, and while similar to Earth’s atmosphere in some ways, such as being rich in nitrogen, it also holds surprises for planetary scientists. Analysis of data from Cassini of a huge cloud which hovers over the moon’s south pole shows that it is both toxic and colder than expected.
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.
