Titan’s second largest lake—Ligeia Mare—appears to be placid, suggesting that there are no winds blowing in that region. That’s the conclusion of a study in Geophysical Research Letters based on data from the Cassini spacecraft’s flyby of Saturn’s largest moon, Titan, on 23 May 2013. The researchers used radar observations to glean insights into the weather patterns above the lake, which other measurements have shown is most likely composed of liquid methane. They also found that the terrain around the lake is most likely made of solid organic material, rather than water ice.
