Heat generated by the gravitational pull of moons formed from massive collisions could extend
the lifetimes of liquid water oceans beneath the surface of large icy worlds in our outer solar system.
Heat generated by the gravitational pull of moons formed from massive collisions could extend
the lifetimes of liquid water oceans beneath the surface of large icy worlds in our outer solar system, according to new NASA research.
The team would like to develop and use even more accurate models of tidal heating and TNO interiors to determine how long tidal heating can extend
the lifetime of a liquid water ocean and how the orbit of a moon evolves as tidal heating dissipates energy.

Findings published today in the journal Astrobiology reveal the habitable
lifetime of planet Earth - based on our distance from the sun and temperatures at which it is possible for the planet to have
liquid water.
Hence, for roughly half
of its
lifetime, Venus could have been a habitable planet with
liquid water (David Shiga, New Scientist, October 10, 2007).
But the more general statement that I used, «increasing the endurance
of cloud
liquid water», does not always translate into longer cloud
lifetimes, particularly in the widespread areas
of nearly overcast marine stratocumulus which dominate considerable areas
of the globe.
