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.

Ethane freezes at — 295ºF and boils at — 128ºF.

Their decaying corpses could release enough methanethiol and ethane gas to briefly show up in the atmosphere, but again we'd have to be looking at the right time.

With an increase in pressure, water and carbon dioxide remain stable, but at pressures above 93 gigapascals (0.93 million atmospheres) methane begins to decompose forming heavy hydrocarbons — ethane, butane, and polyethylene.

Molecular nitrogen (N2) dominates the atmosphere (at altitudes of less than 1800 kilometers or so), whereas methane (CH4), acetylene (C2H2), ethylene (C2H4), and ethane (C2H6) are abundant minor species and likely feed the production of an extensive haze that encompasses Pluto.

As a proof - of - concept for the new antenna - reactor catalysts, Swearer, Halas and colleagues conducted acetylene conversion tests at LANP and found that the light - driven antenna - reactor catalysts produced a 40 - to - 1 ratio of ethylene to ethane, a significant improvement in selectivity over thermal catalysis.

There is probably water - ice at depth on Pluto, but the surface ice is a mixture of frozen methane, ethane, carbon monoxide and nitrogen.

From his ethane research and other international studies, he learned that there appears to be a much higher ethane source in the earth's Northern Hemisphere than in the Southern and a higher leak rate in the central United States than in more eastern oil and gas fields, and that some oil and gas fields in the central United States leak at much higher rates than others.

He knew he needed to find metals that were deft at breaking the carbon - hydrogen bonds that are at the heart of methane, ethane, and propane, short hydrocarbons known as alkanes, and then add in oxygen atoms that would transform the alkanes into alcohols.

Consider this whimsical snippet from a 2007 Titan - themed poem by study co-author Mike Malaska, a scientist in the Planetary Ices Group at the NASA Jet Propulsion Laboratory: «Methane sky; ethane drizzle.Surface made of organic shizzle.Dunes of plastic; it's fantastic.Let's get stickyand electrostatic.»

Nickel - gallium thin films of various stoichiometries were found to reduce CO2 to methane, ethane, and ethylene, at overpotentials lower than the best polycrystalline catalyst, copper.

There are no jolly elves at Titan's north pole; liquid methane and ethane seas appear as splotchy features near the moon's poles.

«Recent data from NSF - funded research in both Greenland and Antarctica demonstrate that fossil - fuel related emissions of both methane and ethane, two of the most abundant hydrocarbons in the atmosphere, declined at the end of the twentieth century... causes of the decline in methane emission rates to the atmosphere have been puzzling scientists for some time.

Natural gas liquids (NGLs) ethane and propane get extracted and sent to a «cracking facility» where ethane is made into ethylene (the foundation of polyethylene - the most common plastic in the world, frequently used for packaging, bottles, and synthetic clothing), and at a dehydrogenation plant, propane is made into propylene (the foundation of polypropylene - a plastic commonly found in food packaging and vehicle manufacturing).

Dozens of Titan's lakes individually have the equivalent of at least this much energy in the form of methane and ethane.
