Europa

Some regions near the equator are slightly darker and have a mottled appearance. This indicates a young and active surface: based on estimates of the frequency of bombardment that Europa experiences, the surface is about 20 to 180 million years old. Europa's icy crust gives it an albedo — light reflectivity — of 0. The existence of deep ocean vents on the ocean floor on Earth have led some scientists to speculate that there could be a possibility of life on Europa. Size comparison of Europa lower left with the Moon top left and Earth right Europa is slightly smaller than the.

Studies of how tidal heating should affect Europa suggested that a global subsurface ocean might exist within the icy moon today. Confirmation of the presence of liquid water and a long-term source of energy would open the possibility that some form of life exists on Europa. One example is flexure analysis, in which Europa's crust is modeled as a plane or sphere weighted and flexed by a heavy load. Meanwhile, a follow-up mission to be launched two years after—called Europa Lander, which would put some kind of device on the crusty surface—has become less certain. Europa's seafloor could be heated by the moon's constant flexing, driving hydrothermal activity similar to undersea volcanoes in Earth's oceans.

Forget the Moon—We Should Go to Jupiter’s Idyllic Europa

To prepare for the new mission, scientists are trying to squeeze all the information they can out of Galileo's data — and that's where the reprocessed images come in. If you are looking for life in the solar system, maybe start with the icy moons. Although the moons appear close together in this view, a gulf of 490,000 miles separates them. Based on Europa's icy composition, scientists think the most likely material to create this magnetic signature is a global ocean of salty water. This evidence of both crustal spreading at bands and convergence at other sites suggests that Europa may have active , similar to Earth.

Because hydrogen peroxide decays into oxygen and water when combined with liquid water, the authors argue that it could be an important energy supply for simple life forms. All planets and their moons experience this, thanks to our moon for the tides , but Jupiter is so huge that it really pushes and pulls its moons as they orbit around, and that creates friction. The icy surface also makes the moon one of the most reflective in the solar system. In 1892, the discovery of , whose orbit lay closer to Jupiter than those of the Galilean moons, pushed Europa to the third position. Bulletin of the American Astronomical Society. Bringing the spacecraft in and out of the zone will extend its lifetime and make it easier to transmit data back to Earth. If confirmed, the lakes could be yet another potential habitat for life.

Europa, moon of Jupiter

The red line shows a trajectory of the Galileo spacecraft during a typical flyby E4 or E14. Europa's immense network of crisscrossing cracks serves as a record of the stresses caused by massive tides in its global ocean. A 3D model of Jupiter's moon Europa, an icy moon with a hidden subsurface ocean. Over billions of years this process has created a moon covered in what looks like jigsaw pieces. This dramatic image of a volcanic eruption taking place on Io was made by the Long Range Reconnaissance Imager aboard New Horizons on February 28, 2007, from about 1.

Greek Myth about Europa

Thus, a lack of large impact craters suggested that the moon's surface was relatively young and implied that something had erased them - such as icy, volcanic flows, or settling of the icy crust under its own weight. An elaborate tracery of ridged plain on the icy surface of Europa, as imaged by the Galileo orbiter on December 16, 1997. Recent data from the orbiter showed that Europa has an induced magnetic field through interaction with Jupiter's, which suggests the presence of a subsurface conductive layer. One of its major goals is to seek out evidence of the apparent plumes that Hubble researchers spotted several times. There will be nine scientific instruments on board including cameras, radar to peer beneath the ice and try to figure out its thickness, a magnetometer to measure the magnetic field and by extension, how salty the ocean is , and a thermal instrument to search for signs of eruptions.
