Earth’s weather satellites just spent 10 years watching Venus — here’s what they found

Japanese meteorological satellites Himawari-8 and -9 have successfully monitored Venus' cloud-top temperature changes, revealing new patterns in temperature structure. Researchers from the University of Tokyo used infrared images from 2015-2025 to estimate brightness temperatures on various timescales. This breakthrough demonstrates that weather satellites can provide valuable long-term data on Venus' atmosphere, complementing future planetary missions and ground-based observations. The study's innovative approach opens new possibilities for monitoring other solar system bodies, potentially contributing to a better understanding of planetary evolution.
