哈佛研究显示 古代火星因大气氢 产生温度 支持液态水 Harvard study reveals ancient Mars had bouts of warmth, supporting liquid water, due to atmospheric hydrogen.

哈佛的研究人员发现 古代火星大气中的氢 尽管离太阳更远 却保持了地球的暖度 足以支撑液态水 Researchers from Harvard have found that hydrogen in ancient Mars' atmosphere kept the planet warm enough to support liquid water, despite being farther from the Sun. 这种热量发生在大约4000万年的时间里, 由从水中产生的氢与地面反应所驱动。 This warmth occurred in episodes over about 40 million years, driven by hydrogen building up from water reacting with the ground. 该研究有助于解释火星的气候历史和过去生命的潜力,提供对行星进化的深刻认识。 The study helps explain Mars' climate history and the potential for past life, offering insights into planetary evolution.
