新的研究表明火星的红毛来自水成矿物质, 表明一个湿润的、可能可居住的过去。 New study suggests Mars' red hue is from water-formed minerals, indicating a wetter, potentially habitable past.

最近的研究表明火星的红色是氟水化合物造成的, 一种形成于冷水中的氧化铁, 这表明一个湿润的过去 能够维持液体水。 Recent research suggests Mars' red color is due to ferrihydrite, an iron oxide that forms in cool water, indicating a wetter past capable of sustaining liquid water. 这挑战了以前的信念, 红石在干燥条件下形成, 导致红色. This challenges previous beliefs that hematite, formed in dry conditions, caused the red color. 该研究将来自火星飞行任务的数据与实验室实验结合起来,表明火星可能拥有数十亿年前的可居住环境,比先前的想象更早,有数十亿年前的水。 The study, combining data from Mars missions with lab experiments, shows Mars likely had a habitable environment with water billions of years ago, earlier than previously thought.
