科学家发现了维纳斯火山活动的第一个直接证据 利用雷达数据 揭示了巨大的地下熔岩管 Scientists found the first direct evidence of volcanic activity on Venus, revealing a massive underground lava tube using radar data.

利用来自美国航天局麦哲伦号航天器的雷达数据 查明了行星表面下方的一座巨大的地下熔岩管 科学家们发现了维纳斯火山活动的第一个直接证据 Scientists have found the first direct evidence of volcanic activity on Venus, identifying a massive underground lava tube beneath the planet's surface using radar data from NASA’s Magellan spacecraft. 该发现由特伦托大学的研究人员领导,发表在《自然通讯》上,揭示了Nyx Mons区域的一个天窗,表明古熔岩流可能形成的熔岩管破裂部分。 The discovery, led by researchers at the University of Trento and published in Nature Communications, reveals a skylight in the Nyx Mons region, indicating a collapsed section of a lava tube likely formed by ancient lava flows. 该管估计至少长45公里,比地球、火星和月球上的类似结构还要大。 The tube, estimated to be at least 45 kilometers long, is larger than similar structures on Earth, Mars, and the Moon. 由于金星的厚云块光学成像,雷达对于探测坑链和地形萧条等表面特征至关重要。 Because Venus’s thick clouds block optical imaging, radar was essential for detecting surface features like pit chains and terrain depressions. 调查结果支持了过去火山活动的理论,并强调了即将到来的飞行任务 -- -- NASA的Veritas和欧空局的Envision -- -- 的重要性,这些飞行任务将利用先进的雷达更详细地探索金星的表面和地下。 The findings support theories of past volcanic activity and highlight the importance of upcoming missions—NASA’s Veritas and ESA’s Envision—which will use advanced radar to explore Venus’s surface and subsurface in greater detail.
