Europa (Jupiter II), the second of the four Galilean moons, is the second closest to Jupiter and the smallest at 3121.6 kilometers in diameter, which is slightly smaller than Earth's Moon. The name comes from a mythical Phoenician noblewoman, Europa , who was courted by Zeus and became the queen of Crete , though the name did not become widely ...
To support an Earth-like atmosphere for about 4.6 billion years (Earth's current age), a moon with a Mars-like density is estimated to need at least 7% of Earth's mass. [20] One way to decrease loss from sputtering is for the moon to have a strong magnetic field of its own that can deflect stellar wind and radiation belts.
A montage of Jupiter and its four largest moons (distance and sizes not to scale) There are 95 moons of Jupiter with confirmed orbits as of 5 February 2024. [1] [note 1] This number does not include a number of meter-sized moonlets thought to be shed from the inner moons, nor hundreds of possible kilometer-sized outer irregular moons that were only briefly captured by telescopes.

The James Webb Space Telescope has detected carbon, a building block of life, on the surface of Jupiter’s icy moon Europa.
A found footage film, it recounts the fictional story of the first crewed mission to Europa, one of the four Galilean moons of Jupiter. Despite a disastrous technical failure that causes the loss of all communications with Earth, and a series of further crises, the crew continues its mission to Europa and finds mounting evidence of life on the ...
