Philosophical Transactions of the Royal Society of London. Series A: Physical and Engineering Sciences, 1994 Venus as a planet resembles the Earth, but has a much hotter and denser atmosphere due to an extreme case of the greenhouse effect, caused by compositional differences and the thick cloud cover. Studies of the lower atmosphere are inhibited by the cloud opacity, which makes remote measurements at most frequencies short of the radio range quite ...

Venus Atmospheric Composition In Situ Data: A Compilation
Earth and Space Science, 2019 The Venus atmosphere is of significant interest yet only rudimentary solid data have been gathered about its composition and chemistry. These measurements are scattered through time and place and are limited by parameters such as resolution and error ...

Photochemistry of the Venus Atmosphere [PDF]
Journal of the Atmospheric Sciences, 1973 Carbon monoxide, produced in the Venus atmosphere by photolysis of CO_2, is removed mainly by reaction with OH. The radical OH is formed in part by photolysis of H_2O_2, in part by reaction of O with HO_2. Photolysis of HCl provides a major source of H radicals near the visible clouds of Venus and plays a major role in the overall photochemistry.

The Atmospheres of Mars and Venus [PDF]
Annual Review of Astronomy and Astrophysics, 1971 Of all the planets which may exist in the Universe, only nine have been studied by man. As a result, one cannot classify planets with the same confidence that one has in classifying stars; there is no theory of planetary evolution comparable in development to the theory of stellar evolution.

The Demographics of Terrestrial Planets in the Venus Zone
The Astronomical Journal, 2023 Understanding the physical characteristics of Venus, including its atmosphere, interior, and its evolutionary pathway with respect to Earth, remains a vital component for terrestrial planet evolution models and the emergence and/or decline of planetary ...

Solar energetic particle interactions with the Venusian atmosphere [PDF]
Annales Geophysicae, 2016 In the context of planetary space weather, we estimate the ion production rates in the Venusian atmosphere due to the interactions of solar energetic particles (SEPs) with gas.

Extended Rift‐Associated Volcanism in Ganis Chasma, Venus Detected From Magellan Radar Emissivity
Geophysical Research Letters, 2022 Exploration of Venus in the 1970–1990s revealed that the geology of Venus, the most Earth‐like of the terrestrial planets, was decidedly un‐Earth‐like, with no plate tectonics, and no record of the first 80% of its history.

The Chemical Composition of the Atmosphere of Venus [PDF]
Symposium - International Astronomical Union, 1971 The chemical composition sensors on the Venera-4, -5, and -6 spacecraft are described. The mixing ratio by volume of carbon dioxide is determined to be 97 (+3, −4)%; nitrogen, less than 2%, oxygen, less than about 0.1%; and water vapor at the 25 °C temperature level, on the order of 10 mg/l, an amount large enough to imply that the clouds of Venus are ...

HOW VENUS BECAME COOL: SOCIAL AND MORAL DIMENSIONS OF BIOSIGNATURE SCIENCE
Zygon, 2021 A 2020 scientific report indicated the presence of phosphine, a potential biosignature chemical, in the atmosphere of Venus. As a result, Venus instantly became a global cultural celebrity.
