![]() ![]() If you've got the ingredients, it's there," he added. "Because wherever we look in Earth's oceans, for the past 200 years, when we've said, 'this is a barren desert life doesn't exist.' It's always there. And, oceanographers tell him: "'Curt, if it's got all this stuff, the life's there, trust us." That implies there is something inside helping to. Ganymede is the only moon in the solar system known to have a substantial magnetosphere. If it were not orbiting as Jupiter’s largest moon, it could be considered a dwarf planet. Niebur added Europa is the "most likely place" humans might find conditions that could support life beyond Earth. Ganymede is the largest moon in the solar system, and is larger than the planet Mercury. More Facts About Saturn’s Frozen Moon Tethys Tethys was one of four Saturnian moons to be discovered by Giovanni Cassini (along with Dione, Rhea and Iapetus). "If we find bacteria on Europa, or Mars or elsewhere, there's likely going to be intelligent life somewhere in the vast universe," he added.Įuropa is not the only one of Jupiter's moons with the potential to harbor alien life, with Enceladus and Callisto also of interest to scientists.īut Dr. This was confirmed by Hubble Space Telescope observations. Ganymede has a thin atmosphere that appears to contain oxygen. Several smaller worlds likely accreted together to make this moon. Shojo and magical girl anime fans have much to thank Naoko Takeuchi for. Ganymede was likely formed in place around the infant Jupiter in the early solar system. The first hints of water underneath the moon’s surface did not come until 369 years later, when the two Voyager probes flew through the Jupiter system, providing the first detailed images of Europa. Despite the moon being discovered in 1789, and initially being called Saturn II (the 2 nd moon from Saturn), it wasn’t until 1847 that its name was changed to Enceladus to avoid confusion after additional moons around Saturn were discovered. The other Galilean moons are Io, Ganymede and Callisto.Even though it is the smallest of the Galilean moons, Europa is still the sixth largest of the 181 moons in the solar system. The dark areas appear to contain clays and organic materials. Because of this, it and the three other largest moons of Jupiter Io, Ganymede, and Callisto are called the Galilean moons.

Curt Niebur, lead scientist for Outer Planet Science in NASA's Planetary Science Division, told Newsweek the probe's mission is to help answer: "Does Europa have all the conditions all the ingredients such that it could be habitable, that life could exist?'" Europa is the sixth closest moon of Jupiter and is the smallest of the Galilean moons discovered by Galileo. NASA is intrigued enough to send an unmanned spacecraft to Europa in October 2024.ĭr. ![]() Europa, Moon of Jupiter CORBIS/Getty ImagesĮuropa is a frozen, icy world world but many scientists are confident that below the frozen surface lies a salt-water ocean and a rocky seafloor. ![]()
