The scientific consensus is that a layer of liquid water exists beneath Europa's surface, and that heat from tidal flexing allows the subsurface ocean to remain liquid. [ 19 ] [ 80 ] Europa's surface temperature averages about 110 K (−160 °C ; −260 °F ) at the equator and only 50 K (−220 °C; −370 °F) at the poles, keeping Europa's ...
Europa Clipper (previously known as Europa Multiple Flyby Mission) is a space probe developed by NASA to study Europa, a Galilean moon of Jupiter. It was launched on October 14, 2024. [ 15 ] The spacecraft will use gravity assists from Mars on March 1, 2025, [ 10 ] and Earth on December 3, 2026, [ 11 ] before arriving at Europa in April 2030 ...
Models of how Europa is affected by tidal heating require a subsurface layer of liquid water in order to accurately reproduce the linear fracturing of the surface. Indeed, observations by the Galileo spacecraft of how Europa's magnetic field interacts with Jupiter's field strengthens the case for a liquid, rather than solid, layer; an ...

New research suggests there's less oxygen on the icy surface of Jupiter's moon Europa than thought — and that could affect what if any life might be lurking in the moon’s underground ocean.
Heller et al. (2021) estimated that shortly after the Moon was formed, when the Moon orbited 10-15 times closer to Earth than it does now, tidal heating might have contributed ~10 W/m 2 of heating over perhaps 100 million years, and that this could have accounted for a temperature increase of up to 5°C on the early Earth.

It is thought that they may be composed of ice II or other polymorph of water ice. [2] The prime example of this class of object is Europa. Icy moons warmed by tides may be the most common type of celestial body in the galaxy to have liquid water, [3] and thus the most likely type of object to possibly have water-based life.
