Another explanation is that these features sit atop vast lakes of liquid water that are encased in the crust – distinct from it’s interior ocean.Europa’s icy crust gives it an albedo (light reflectivity) of 0.64, one of the highest of all moons. If it can be demonstrated that life formed independently in two places around the same star, it would then be reasonable to suspect that life springs up in the universe fairly easily once the necessary ingredients are present, and that life might be found throughout our galaxy, and the universe. If we eventually find some form of life at Europa (or Mars or Enceladus for that matter), it may look like microbes, or maybe something more complex. This would mean the moon is geologically active in the present day.
As the ice shell distorts and flexes from tidal forces, warmer and less-dense ice would rise, carrying the ocean samples to the surface where a spacecraft could analyze it remotely, using infrared and ultraviolet instruments, among others. Infrared images from NASA's Juno spacecraft are providing the first glimpse of Ganymede's icy north pole. Europa Clipper will explore Jupiter's icy moon in-depth during multiple flybys, studying whether Europa could harbor conditions suitable for life. However, other research suggests that the tidal locking may not be full, as a non-synchronous rotation may be present.Basically, this means that Europa could spin faster than it orbits Jupiter (or did so in the past) due to an a asymmetry in its internal mass distribution where the rocky interior spins slower than its icy crust.
The Galileo spacecraft did a long-term mission at Jupiter and its moons between 1995 and 2003. Thus, tidal flexing kneads Europa’s interior and gives it a source of heat, possibly allowing its ocean to stay liquid while driving subsurface geological processes. You will receive a verification email shortly.There was a problem. Europa orbits Jupiter at about 417,000 miles (671,000 kilometers) from the planet, which itself orbits the Sun at a distance of roughly 500 million miles (780 million kilometers), or 5.2 astronomical units (AU). A research team led out of NASA’s Goddard Space Flight Center has detected water vapor for the first time above Europa’s surface. Europa's icy crust gives it an albedo — light reflectivity — of 0.64, one of the highest of all of the moons in the entire solar system.Scientists estimate that Europa's surface is about 20 million to 180 million years old, which makes it fairly young.Pictures and data from the Galileo spacecraft suggest Europa is made of silicate rock, and has an iron core and rocky mantle, much like Earth does. Decades-old found footage from NASA's abandoned Apollo 18 mission, where three American astronauts were sent on a secret expedition, reveals the reason the U.S. has never returned to the moon.

Europa, Jupiter's moon is known to have potential to support life. If confirmed by follow-up observations, the plumes of water could be studied by future spacecraft similar to how the Cassini sampled the plume of Saturn’s moon Enceladus.One of the most important measurements made by the Galileo mission showed how Jupiter's magnetic field was disrupted in the space around Europa.
That increases the gravitational pull on Europa, and distorts its shape. So the effects of diminished gravity on permanent occupants, not to mention on the development of fetal tissue and childhood development for those colonists born on Europa, is currently unknown.It is also speculated that alien organisms may exist on Europa, possibly in the water underlying the moon’s ice shell.
But again, this would depend on their average temperatures and their salt content.Also, there is evidence suggesting that hydrogen peroxide is abundant across Europa’s surface.

Though accessing it would be difficult, and could require drilling to depths of several kilometers, the sheer abundance of water on Europa would be a boon for colonists.
This page showcases our resources for those interested in learning more about ocean worlds. The effects of low gravity are an active field of study, based largely on the extended stays of astronauts in low Earth orbit. Europa is one of the Galilean moons of Jupiter, along with Io, Ganymede and Callisto. Its orbit is nearly circular. An international crew of astronauts undertakes a privately funded mission to search for life on Jupiter's fourth largest moon. i’d be riveted.Mg Sulfate (aka Epsom salt) is white. Symptoms of extended exposure to microgravity include loss of bone density, muscle atrophy and a weakened immune system.Effective countermeasures for the negative effects of low gravity are well-established, including an aggressive regimen of daily physical exercise. Scientists could then study the material’s composition to determine whether Europa’s ocean might be hospitable for some form of life.Life as we know it seems to have three main requirements: liquid water, the appropriate chemical elements, and an energy source.
