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 ...
Life may exist in Europa's under-ice ocean. So far, there is no evidence that life exists on Europa, but the likely presence of liquid water has spurred calls to send a probe there. [36] Recurring plume erupting from Europa. [37] The prominent markings that criss-cross the moon seem to be mainly albedo features, which emphasize low topography.
Water vapour is sometimes considered conclusive evidence for the presence of liquid water, although atmospheric water vapour may be found to exist in many places where liquid water does not. Similar indirect evidence, however, supports the existence of liquids below the surface of several moons and dwarf planets elsewhere in the Solar System. [1]
"Europa is an ice covered moon of Jupiter, about the size of Earth's moon, but believed to have a global subsurface ocean that contains more than twice the water of all of Earth's oceans combined ...
The goals of Europa Clipper are to explore Europa, investigate its habitability and aid in the selection of a landing site for the proposed Europa Lander. [52] [74] This exploration is focused on understanding the three main requirements for life: liquid water, chemistry, and energy. [75] Specifically, the objectives are to study: [32]
This is a list of craters on Europa.The surface of Jupiter's moon Europa is very young, geologically speaking, and as a result there are very few craters.Furthermore, as Europa's surface is potentially made of weak water ice over a liquid ocean, most surviving craters have slumped so that their structure is very low in relief.
The research team traveled to the lake in the summers of 2019 and 2020, and with the help of ground-penetrating radar, discovered that Lake Enigma—true to its name—contained a secret: liquid ...
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.
