Gas hydrates have received considerable attention due to their important role in flow
assurance for the oil and gas industry, their extensive natural occurrence on Earth and …

Jupiter's icy moon, Europa, harbors a subsurface liquid water ocean; the prospect of this
ocean being habitable motivates further exploration of the moon with the upcoming NASA …

Saturn's moon Enceladus has an ice-covered ocean; a plume of material erupts from cracks
in the ice. The plume contains chemical signatures of water-rock interaction between the …

Jets of water ice from surface fractures near the south pole of Saturn's icy moon Enceladus
produce a plume of gas and particles,,,. The source of the jets may be a liquid water region …

Context. Models of the young solar nebula assume a hot initial disk in which most volatiles
are in the gas phase. Water emission arising from within 50 AU radius has been detected …

We review the reservoirs of methane clathrates that may exist in the different bodies of the
Solar System. Methane was formed in the interstellar medium prior to having been …

Since its discovery in the first half of the 20th century, scientists have puzzled over the
origins of Titan's atmosphere. Current models suggest that atmospheric N 2 on Titan may …

We present 1–5μm IR reflectance spectra of CO2 clathrate hydrates acquired under
temperature and pressure conditions representative of the icy moons' surfaces. The IR …

Abstract Dwarf planets Eris and Makemake have surfaces bearing methane ice of unknown
origin. This ice can provide important insights into the origin and evolution of volatiles in the …

We present new experimental data on the liquidus of ice polymorphs in the H 2 O–NH 3
system under pressure, and use all available data to develop a new thermodynamic model …
