国际研究团队利用辐射传输建模方法，对金星云层中的神秘吸收物质的光学性质进行了量化分析 1。研究表明，这种未知物质必须具有极强的紫外光吸收能力，在375纳米波长处的十进制吸收系数达约1278厘米⁻¹，这一数值意味着无论是有机还是无机候选物质，都需要以极高的浓度存在才能解释观测到的现象 1。若该物质为类似卟啉类颜料的有机分子，其所需浓度约为10克/升 1。
研究发现，这种吸收体在365至455纳米范围内呈现相对尖锐的吸收特征，与浓硫酸中形成的有机物棕黑色焦油状混合物的光学表现明显不同 1。该研究已发表于《Astrobiology》期刊 1。未来的金星探测任务计划通过实验室测试和直接大气测量来验证这些约束条件，其中拟使用的Autofluorescence Nephelometer仪器将搭载于Rocket Lab的金星任务中 1。
An international research team has established new quantitative constraints on a mysterious absorptive substance hidden within Venus's clouds through radiative transfer modeling.1 The unknown material must possess exceptionally strong ultraviolet light absorption capability, with a decimal absorption coefficient of approximately 1,278 cm⁻¹ at a wavelength of 375 nanometers, requiring both organic and inorganic candidate substances to exist at very high concentrations to explain the observed phenomena.1
The absorption spectrum displays relatively sharp absorption features across the 365–455 nanometer range, distinguishing it from dark brown tarry mixtures formed by organic matter in concentrated sulfuric acid.1 If the absorptive agent consists of organic molecules similar to porphyrin pigments, the required concentration would be approximately 10 grams per liter.1 The research, published in Astrobiology on September 12, 2026, represents a significant step toward identifying the composition of Venus's mysterious atmospheric component.1 Future Venus exploration missions will verify these constraints through laboratory testing and direct atmospheric measurements, with an Autofluorescence Nephelometer instrument planned for deployment on a Rocket Lab Venus mission.1
