Titan and its subsurface ocean has tides

It is this subsurface ocean, or rather its interaction with the ice shell that covers it, that a team of researchers led by the Catholic University of Louvain (UCLouvain) in Belgium hope to better understand. More specifically, they wish to understand how the ocean’s depth and the pressure exerted by the icy shell on the underground water body influence the formation of tidal motions and currents inside of it.

When I first heard of “Attack on Titan,” I was disappointed to learn that it didn’t take place actually on Titan. (The title in English is a mistranslation. It should be “Attack of the Titans” or “The Titans Attack” or even “Attacking Titans,” depending.) In any case, it’s a disgusting manga/anime with nothing to do with the icy moon of Saturn. Except for the name. And even that’s a misuse (they should have used “giant” as the storyline is very loosely based on Ymir and the frost giants of Scandinavian myth).

Anyway. It’s a fascinating moon the size of the planet Mercury with a liquid ocean and (mostly) nitrogen atmosphere, making it a candidate for extraterrestrial life. Here’s a cool view of it: https://solarsystem.nasa.gov/moons/saturn-moons/titan/overview/

Remember the Titan! Uh. The moon. Called Titan.

Cyclopropenylidene is the second cyclic or closed-loop molecule detected at Titan; the first was benzene in 2003. Benzene is an organic chemical compound composed of carbon and hydrogen atoms…Cyclic molecules are crucial because they form the backbone rings for the nucleobases of DNA, according to NASA.

The only moon in the solar system that has an atmosphere…4 times denser than the Earth, actually.

Except it rains ethane and methane and is -270C. Not exactly a place to plan a vacation.

But the organic molecules may (BIG may) hint at life of some sort.

And we only have to wait until 2034 to find out!
