  • The authors define the cenotectic — the low-temperature stability limit for a liquid under arbitrary thermodynamic conditions — and measure it for several aqueous solutions of relevance to extraterrestrial oceans using isochoric freezing/melting.

  • Habitability of exoplanet’s deepest oceans could be limited by the presence of high-pressure ices at their base. New work demonstrates that efficient chemical transport within deep planetary ice mantles is possible through significant salt incorporation within the high-pressure ice.

  • Liquid water is key for life as we know it. Here, the authors show even with a modest geothermal heat flow, subglacial oceans of liquid water can form at the base of and within the ice sheets on exo-Earths, which may provide habitable conditions for an extended period.
