In 1982, in Arthur Clarke's novel "2001 A Space Odyssey", there was a message broadcast to humans: "This world is yours, except for Europa... It is strictly forbidden to attempt to land!" The aliens turned Jupiter and Europa into What is the purpose of a small solar system? The real reason is that they protect the life that has just sprouted on Europa. Clark's science fiction is based on facts in many places, and it is also correct to say that there may be life in the harsh environment of Europa. And these life needs sunlight and heat to melt the ice to end the ice age and evolve. A 1977 discovery provided optimistic evidence that life could emerge or colonize Europa. The discovery was made on the earth's seabed, where photo retouching service a team led by Robert Ballard, a professor of oceanography in the United States, found that very high-temperature seafloor hydrothermal vents were rich in minerals. Next to this hot spring, there is a small self-sufficient ecosystem, in which the main organisms are bacteria and giant tube worms as long as arms. If life can flourish so vigorously in this place where the sun never sees the sun, will there be life in the bottom ocean where Europa’s sunlight cannot reach? Despite high hopes, funding fell short of the target. NASA once expected to launch an artificial satellite orbiting Europa in 2020, but so far, there is still not enough funding. (Editor's note: NASA and the European Space Agency announced in 2017 that the two agencies would collaborate on a "joint mission to Europa" to launch a lander around 2025.) The idea was to make a map of the icy moon and then measure it the width of the ocean. It also detects carbon molecules on the surface, which are a necessary condition for life.
