New analysis shows how sulfur clouds can form in Venus’ …
2022年8月16日 · The results clarify the planet’s source of sulfur-rich clouds, hint at the identity of the long-mysterious ultraviolet-absorbing compound, and offer a note of caution for efforts to geoengineer a solution to climate change by injecting sulfur into Earth’s atmosphere.
Venus' atmosphere: Composition, clouds and weather | Space
2024年1月10日 · The normal yellow form of sulfur powder is made up of S 8 molecules. The clouds on Venus appear to be made of sulfuric acid droplets that condense onto smaller particles made of polysulfur...
Iron-sulfur chemistry can explain the ultraviolet absorber in the ...
2024年1月3日 · In Venusian clouds, water activity can be correlated to the concentrations of sulfuric acid and the atmospheric height. This study presents the UV measurement of synthetic rhomboclase and AFS to demonstrate that a combination of these two minerals, in addition to dissolved iron, can adequately explain the observed UV absorbance.
Sulfur on Venus: Atmospheric, Surface, and Interior Processes
2024年9月25日 · Sulfur-bearing species play critical roles in atmospheric physical-chemical processes, atmosphere-surface interactions, and the geological evolution of Venus. This chapter provides a comprehensive overview of (1) Instrumental data on the abundance and speciation of sulfur in atmospheric and crustal materials,
Venus Facts - Science@NASA
Photos snapped before the landers fried show a barren, dim, and rocky landscape, and a sky that is likely some shade of sulfur yellow. Volcanoes and tectonic forces appear to have erased most traces of the early surface of Venus.
Sulfur behavior in Venus atmosphere explained - ScienceDaily
2016年4月26日 · In the new paper, Krasnopolsky presents the first photochemical model of the formation of sulfur particles in Venus's clouds. In particular, the model included certain processes of the...
In Depth | Venus – NASA Solar System Exploration
Photos snapped before the landers fried show a barren, dim, and rocky landscape, and a sky that is likely some shade of sulfur yellow. Venus’ atmosphere is one of extremes. With the hottest surface in the solar system, apart from the Sun itself, Venus is hotter even than the innermost planet, charbroiled Mercury.
Production and Reactions of Organic Molecules in Clouds of Venus
2023年12月22日 · For half a century, the possibility of organic molecules in sulfuric acid droplets in the clouds above Venus has been largely discounted. Here, we report the first results from an experimental exploration of this possibility, of primary interest to astronomers but also uncovering reactions that are remarkable to organic chemistry.
