科学家发现火星表面下存在巨大湖泊的证据

Scientists Find Evidence for Vast Lakes Hidden Under Mars’ Surface

水对地球上的生命至关重要,科学家们认为水的存在是外星世界潜在可居住性的最重要指标。例如,在几十亿年前,火星表面的一部分被水浸没时,火星可能短暂地具备了维持生命的适当条件,但目前还不清楚这颗红色星球今天有多潮湿。

Water is so essential for life on Earth that its presence is considered by scientists to be the most important indicator of potential habitability on alien worlds. For instance, Mars may have briefly had the right conditions to support life billions of years ago, when portions of its surface were awash in water, but it is unclear just how wet the red planet is today.

2018年,科学家探测到可能存在一个藏在冰冷的火星南极下约一公里处的咸水水库。周一发表在《自然天文学》上的一项研究表明,新的观测结果“进一步证实了液态水体的存在”,“表明附近还有其他潮湿地区”。

In 2018, scientists detected the possible presence of a salty water reservoir hidden about a kilometer under the icy Martian south pole. New observations now “strengthen the claim of the detection of a liquid water body” and “indicate the presence of other wet areas nearby,” according to a study published on Monday in Nature Astronomy.
