新的研究显示,木星的一个卫星——木卫二有丰富的重要矿物质,还有从地下海洋里喷发的壮观水柱,这可能是太阳系里又一个宜居之地。木卫二上间歇喷发的两处巨大羽状水柱,高达200公里。通过对哈勃太空望远镜提供的数据进行分析发现,水柱通常在木卫二围绕木星轨道运行时的某些特定时刻喷发,这表明喷发原因是周期性的巨大潮汐力使该星球地下海洋的压力增大,使其 New research shows that one of Jupiter’s moons, Europa, is rich in important minerals and has a spectacular water column that erupts from the ocean floor, which could be another haven in the solar system. Europa on intermittent eruption of two huge plume water column, up to 200 km. An analysis of the data provided by the Hubble Space Telescope found that the water column usually erupted at some specific point during the Europa’s orbit around Jupiter, indicating that the eruption was due to the cyclical, large tidal forces that increased the pressure on the planet’s lower ocean Big, make it
