Lakes On Titan Will Have Layers, Like Lakes On Earth, But for a Completely Different Reason

Lakes on Earth are a common sight in many locales.  They’re central to the recreation and livelihood of millions of people.  Few of those people think of the hydrodynamics that happen in a lake system.  It is common for lakes to stratify into different layers. On Earth that stratification is the result of the sun heating the upper layer of water, which then becomes less dense and floats on top of the colder, more dense layer beneath it.  Now, scientists from the Planetary Science Institute (PSI) have found similar dynamic cycles in a different kind of lake – the ethane and methane lakes on Titan.

Whoa. Lakes on Titan Might be the Craters from Massive Underground Explosions

The Cassini spacecraft ended its mission to Saturn and its moons two years ago when it was sent plunging into Saturn to be destroyed. But after two years, scientists are still studying the data from the Cassini mission. A new paper based on Cassini data proposes a new explanation for how some lakes on Titan may have formed.

Methane-Filled Lakes on Titan are “Surprisingly Deep”

The Cassini mission to Saturn and its moons wrapped up in 2017, when the spacecraft was sent plunging into the gas giant to meet its end. But there’s still a lot of data from the mission to keep scientists busy. A team of scientists working with Cassini data have made a surprising discovery: Titan’s methane-filled lakes are much deeper, and weirder, than expected.
