NASA should focus on discovering a new planet that can replace the Earth. NASA already found out the fact one of Jupiter’s moons may have plumes, or geysers, spraying clouds of water vapor. Scientists suspect that warm, liquid water lives under Europa’s thick ice shell. Given that, this moon is considered a “top candidate” by NASA for life on another world in our solar system. Since the human needs another place to live instead of the Earth because of the environmental pollution and lacking the natural resources, the scientists have to find another planet as fast as they can for human. The research is ongoing and they found many pieces of evidence for the existence of water on Jupiter which is a very important discovery.
