The Search for Life in Europa

On January 8, 1610, Galileo Galilei discovered Europa of Europa (Io, Woodward, Callisto). It is the sixth month and the sixth largest month in the solar system closest to Jupiter. It takes about 5 days for Io to circle Jupiter and to rotate each turn once. This is the reason to always show the same face to Jupiter (It resembles the moon on the earth). It is roughly the size of the Earth's moon, there is water ice on the surface 1 Since the orbit of Europe is eccentric, it creates a higher tide when approaching Jupiter than far.

When it comes to question of where in the solar system it is best to find extraterrestrial life forms, it immediately comes to mind. In this small moon of Jupiter it seems that everything you need is complete - the underground sea of ​​the earth may be the source of heat and chemical nutrients on the ocean floor. However, finding the evidence is not easy; the ocean is under a layer of rather thick ice and is difficult to access. Depending on the location, this may require several meters or several kilometers of ice drilling.

Let's take a closer look at Europe as the owner of life. Europe is the fourth largest satellite of Jupiter, the sixth largest satellite in the solar system. The surface of Europa is covered with ice. From the photographs taken by Galileo (not a spaceship, an astronomer) the surface looks like broken glass, it is repaired with a cold glue, it exudes from the bottom. Low ridge, straight and bent, surface intersection. Flow and cracks, pit and frozen "puddle" - everything suggests a unique geological history. Because of its smooth surface, it is the brightest moon that is the solar system

On Mars, water flowed once. It still produces frost and ice, but since the current state of Mars is very hostile to life, most searches are currently focused on finding signs of past life. Europe, which is almost equal to the size of the Earth's moon, has an Aral Sea under the ice, but it is radiated strongly. Photographs from the Hubble Space Telescope sometimes show that large quantities of material are released from European ice, so future tasks for Jupiter will try to overcome their possible biochemical characteristics and analyze them.
