The scenario of finding aliens in a place very similar to Earth

According to Business Insider, the US Aerospace Agency (NASA) is willing to spend billions of dollars just to answer one of the most important questions people have ever asked: "Whether humans are alone in the universe. la? " In other words, "Is there an alien?".

The primary goal for NASA to find evidence of alien life is Europa - a Jupiter's icy satellite roughly the size of the Moon that hides inside an ocean with even more water. even more than water exists on Earth.

Satellite image of Europa of Jupiter captured by the Galileo spacecraft in the 1990s.

Before NASA sent the Europa Clipper to Europa, they and their partners built a map of the mystical world on the planet to help Europa Clipper's mission to be more effective. Europa Clipper is a solar-powered exploration ship, carrying many high-tech, state-of-the-art scientific devices to capture and record life on Europa.

The map above was built by two research groups that lasted more than a decade. Scientists will use it to plan for the Europa Clipper task, for example predicting what traits can be observed on a particular journey as well as planning expeditions for Europa Clipper, .

Simulate the mission of Europa Clipper.

Dr Alex Patthoff, a geologist and planetary researcher at NASA's Jet Engine Laboratory, told Business Insider: "There has never been a complete global map like before. this map ". Patthoff and his colleagues presented their results at the 2017 US Geological Society meeting in Seattle, USA.

There are even cross-sections with hot, cold areas.

Europa is a promising destination to search for extraterrestrial life, not only because of its ocean, but there is also much evidence of oxygen and other substances in maintaining hot, cold regions on Europa. . According to scientists, Europa's surface has cracks and basically no craters, indicating that rocks containing minerals often sink into the water here. There is even evidence that Europa sprayed water into space but was unsure.

The mission to explore Jupiter's Europa satellite this time is expected to cost between $ 2 and $ 4 billion. And if there is good funding, NASA's Europa Clipper probe will reach the surface of the Europa planet around 2030.
