土星月球土卫二热显示海洋稳定活跃,有生命潜力。 Heat from Saturn’s moon Enceladus reveals a stable, active ocean with potential for life.

土星的月亮土星从土星的土卫二逃出热量表明,土星的潮汐力量驱动着稳定的地下海洋和持续不断的地质活动。 Heat escaping from Enceladus, Saturn’s moon, indicates a stable subsurface ocean and ongoing geological activity, driven by tidal forces from Saturn. 美国航天局的Cassini飞行任务数据显示,热排放不仅在南极——水蒸气和有机材料的羽流喷发——而且来自北极,表明海洋是统一加热的。 Data from NASA’s Cassini mission show heat emission not only at the south pole—where plumes of water vapor and organic material erupt—but also from the north pole, suggesting a uniformly heated ocean. 长时间的稳定性,以及水热活动和化学能量来源,使得恩赛拉多成为寻找外星生命的领先候选者. This stability over long timescales, along with hydrothermal activity and chemical energy sources, makes Enceladus a leading candidate in the search for extraterrestrial life. 美国航天局和欧洲航天局的未来飞行任务旨在直接研究羽流。 Future missions by NASA and the European Space Agency aim to study the plumes directly.
