Titan's Ontario Lacus
Last week, the New York Times ran an article on Alex's Titan research: link.
For those uninitiated into all things planetary science, as I was not long ago, Titan is one of Saturn's moons. Not to be outdone by our own moon, Titan has the unique distinction of being the only other body, besides Earth, in our solar system with an active hydrologic cycle. In other words, it has lakes, evaporation, rain, the works. Only, you won't be swimming in these lakes anytime soon... they're liquid methane.
What Alex's recent research focused on is seasonal changes in Titan's lakes, specifically in Ontario Lacus (pictured above). Ontario Lacus is the largest lake in Titan's southern hemisphere and repeat observations by the Cassini radar over the last few years have shown that the levels of liquid in this lake are dropping over time... confirming a seasonal effect on Titan's hydrologic cycle.
