First science results released on Ultima Thule
... which are then lost to space, allowing for longer-chain chemical reactions to take place involving carbon or nitrogen. Tentative fingerprints of methane, along with water ice have potentially been observed on Ultima by LEISA, say Stern...

A thin layer of ice-trapped gas stops Pluto's oceans from freezing
... say Kamata and colleagues. What’s more the gas in the hydrates is most likely methane, and not nitrogen, which is what Sputnik Planitia is thought to be composed of. These molecules once released, then escape to help fill up Pluto...
