285. 火星岩石发现生命迹象

from 知为谁 · host 知为谁

火星车“毅力号”在火星的耶泽罗撞击坑中发现了一块名为“Cheyava Falls”的岩石,其上带有独特的“豹纹斑点”和“罂粟籽”状标记,美国国家航空航天局(NASA)认为这可能是迄今为止火星上存在古代生命的最清晰迹象。科学家们在《自然》杂志上发表了一篇经过同行评审的论文,阐述了对这些斑点的分析,这些斑点可能由富含铁和磷酸盐的矿物质构成,并与有机化合物和水流的证据同时存在。虽然仍需进一步研究以确认这些特征的生物学起源,但这一发现标志着回答“人类是否在宇宙中是孤独的”这一深刻问题的关键一步。该岩石样本的最终返回地球进行实验室分析,将是验证这一潜在生物特征的重要环节,尽管NASA目前正面临预算挑战,可能会影响未来的样本返回任务。内容来源:https://www.cnn.com/2025/09/10/science/nasa-mars-sapphire-falls-rock-sample
