日本东北大学行星科学家Hiroki Karyu领导的研究团队揭开了困扰科学界数十年的谜团：笼罩金星下层大气的黄色雾霾实际上由陨星燃烧产生的宇宙尘埃与硫酸粒子相互作用而成。1这层神秘的雾霾自1970年代被Venera和Pioneer Venus探测器首次发现以来，其成因一直未被阐明。1
研究团队通过微物理模型分析发现，持续流入的宇宙尘埃足以维持观测到的粒径分布的下层雾霾层。1Karyu指出，"宇宙尘埃的持续流入足以维持观察到的粒径分布的下层雾霾层"。1这些来自宇宙的粒子充当凝聚核，即使远离初始源头，也能促进金星主云层的云形成。1该项研究成果已刊登于《自然天文学》期刊。1
Scientists at Tohoku University in Japan have solved a decades-old mystery surrounding Venus's lower atmosphere. Using microphysical modeling, researcher Hiroki Karyu and his team have determined that the yellow haze first observed in the 1970s by the Venera and Pioneer Venus probes is actually composed of particles formed through the interaction of cosmic dust and sulfuric acid 1. The findings have been published in the journal Nature Astronomy 1.
According to Karyu's research, "the continuous influx of cosmic dust is sufficient to maintain the observed particle size distribution in the lower haze layer" 1. These cosmic particles serve as condensation nuclei, facilitating cloud formation in the main cloud layer even when dispersed far from their initial source 1. The study employed microphysical models to analyze the microscale processes that generate clouds and precipitation on Earth and other celestial bodies 1.
