The brief
For nearly 50 years, Venus’s clouds have been understood as droplets of concentrated sulfuric acid. A 2025 reinterpretation of data inadvertently collected by NASA’s Pioneer Venus Large Probe in 1978 suggests their aerosols may instead be about 60 percent composed of an unknown, exceptionally strong light absorber.
The finding challenges the long-held understanding of Venus’s atmosphere. The exact composition of this absorber remains unknown, and the 1978 data was not originally collected for this purpose.
