The Methods: Photochemical modeling by a Caltech team indicates that ethane, a hydrocarbon detected on Titan by both of the Voyager spacecraft and the European Infrared Space Observatory, is created when solar ultraviolet light breaks down methane, a minor component of Titan's nitrogen - rich atmosphere, into a stew of organic molecules that form a dense orange - brown smog.
Originally it was thought that the ethane condenses into droplets, and rains down in the frigid cold of Titan's — 290 degree Fahrenheit atmosphere.

(The researchers also found ethane, propane and butane in some of the drinking water wells.)
Hunten contends that molecules of ethane can't form droplets, so they instead cling to smog particles in Titan's atmosphere.
The discovery of new materials for separating ethylene from ethane by adsorption, instead of using cryogenic distillation, is a key milestone for molecular separations because of the multiple and widely extended uses of these molecules in industry.

The sea may also be stratified, with more ethane in the deeper layers and methane near the surface.
The fact that the radar signals could bounce off the sea bottom suggests that the seas were more transparent than expected and thus must contain mostly methane, not ethane.
This material can kinetically separate ethylene from ethane with an unprecedented selectivity of ~ 100, owing to its distinctive pore topology with large heart - shaped cages and framework flexibility.
It sits in Ligeia Mare, a sea made of methane, ethane and nitrogen in Titan's northern polar region.
Indeed, in competitive adsorption experiments, the zeolite preferentially adsorbed ethylene from a mixed stream of ethylene and ethane.
Part of the reason for that presupposition is that light coverts methane in the atmosphere to ethane.
If currents occasionally pull methane down to the deeper sea, the methane and ethane can mix, simulations by Daniel Cordier of the University of Reims Champagne - Ardenne in France and colleagues suggest.
The bodies appear to be made mostly of methane, and not mostly ethane as previously thought.
Titan is Saturn's largest moon, a cryogenically cold world with a surface shaped by hydrocarbon rivers and seas fed by methane, ethane and complex organic compounds raining out of its thick, smoggy atmosphere.
NASA's Cassini - Huygens mission showed that Titan has lakes and rivers of liquid ethane and methane, and may have chemistry that is conducive to life.
Methane rain should fall on the lakes but it is vastly more volatile than ethane and propane, so it probably evaporates much faster from lakes, leaving the heavier hydrocarbons behind.
Using radar, infrared, and visual imaging, Cassini has revealed a string of ethane and methane lakes on Titan, making it the only other known world with bodies of liquid on its surface.
That research suggests fossil fuels are behind at least 28 % of that increase — so, she adds, more work is needed to reduce uncertainties and reconcile the ethane - based and isotope - based conclusions.
Cassini has identified ethane in Ontario Lacus, and methane is almost certainly present.
Last year, Lorenz calculated that wind speeds of less than 1 metre per second — calm by terrestrial standards — should be sufficient to produce detectable waves in an ethane lake.
As part of this work, Conley and colleagues analyzed methane and ethane data from 13 research aircraft flights between 7 November 2015 and 13 February 2016 — two days after the leak was finally plugged.
That's puzzling because mixtures of methane and ethane should be less viscous than water, meaning that even light winds can whip up waves.
If they are clouds, they're probably made of ethane, acetylene or hydrogen cyanide, based on what researchers have learned about Pluto's atmosphere — though they might not be clouds, just reflective splotches on
The key ingredient is gas hydrate, a substance that forms when hydrocarbon gases like methane and ethane come into contact with water at the right temperature and pressure.
