Titan Lakes are filled with liquid hydrocarbons. Previous research using images and data collected during Cassini's mission has shown that lakes in the dry regions of the moon near the equator contain traces of vaporised material such as bath rings.
Like the lab conditions, the researchers start with a custom made cryostat, a device that keeps things cold. They filled the cryostat with liquid nitrogen to lower the temperature. Then they slightly warmed the chamber, so the nitrogen turned into gas, which is mostly what the atmosphere of Titan contains. They then thrown into Titan, methane and ethane, as well as other carbon-containing molecules, and searched for what was being formed.
The first thing left out of their hydrocarbon soup was the crystals of benzene. Benzol is perhaps best known as a component of gasoline and is a snowflake molecule made of a hexagonal ring of carbon atoms. But Titan's gasoline was surprising: the molecules were rearranged and allowed the ethane molecules to create a co-crystal.
The researchers then discovered the co-crystal of acetylene and butane, which is probably much more common in titanium than benzene crystals.
In the cold climate of the moon, co-crystals of acetylene-butane can form rings around the moon lakes as liquid hydrocarbons evaporate and the minerals fall – at the same time. According to Cable, salts can form peel on the shores of the Earth's lakes and the seas.
To confirm that Titan has rings of baths with coccysts and other undiscovered hydrocarbon crystals, scientists will have to wait until a spacecraft can say, "We do not know yet whether we have these bath rings, said Cable. "It's hard to see through Titan's turbulent atmosphere."
