根据美国宇航局的一项新研究, 泰坦可能没有全球海洋; 相反, 它的内部有泥和温水口袋. Titan likely has no global ocean; instead, it has a slushy interior with pockets of warm water, according to a new NASA study.

美国航天局领导的一项新的重新分析卡西尼航天器数据的研究表明,土星的月亮巨人可能没有全球地下海洋,相反,土星的冰层下有液态水块,形成一个冰雪的内部。 A new NASA-led study reanalyzing Cassini spacecraft data suggests Saturn’s moon Titan likely lacks a global subsurface ocean, instead featuring a slushy interior with pockets of liquid water beneath its icy crust. 泰坦对土星重力的表面反应拖延了15小时,有证据表明,土星的地表反应是僵硬的、粘稠的内部,而不是自由流出的海洋,指向冰层和融化水层。 Evidence from a 15-hour delay in Titan’s surface response to Saturn’s gravity indicates a rigid, viscous interior rather than a free-flowing ocean, pointing to layers of ice and meltwater. 虽然没有全球海洋得到证实,但可能存在零星的热水区(可能高达20°C),为微生物生命提供了潜在的栖息地。 While no global ocean is confirmed, isolated pockets of warm water—possibly up to 20°C—may exist, offering potential habitats for microbial life. 这些研究结果发表在《自然》上,挑战长期持有的假设,并可能改变对冰冻卫星的理解。 The findings, published in Nature, challenge long-held assumptions and could reshape understanding of icy moons. 将在2020年代发射的美国航天局的“飞龙”飞行任务将探索泰坦的地表和地下,为这一新模型提供第一次直接测试。 NASA’s Dragonfly mission, set to launch in the 2020s, will explore Titan’s surface and subsurface, providing the first direct test of this new model.
