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.

Absorption of Sunlight in the Atmosphere of Venus [PDF]
Science, 1979 In this report the fluxes measured by the solar flux radiometer (LSFR) of the Pioneer Venus large probe are compared with calculations for model atmospheres. If the large particles of the middle and lower clouds are assumed to be sulfur, strong, short-wavelength absorption results in a net flux profile significantly different from the LSFR

Oscillation of Venus' upper atmosphere
Geophysical Research Letters, 2007 Little is known about the variability of Venus' upper atmosphere. We report discovery of a large (∼ ±30–50%) 9‐day period density oscillation, derived from radar tracking of the Magellan spacecraft from 15 Sept 92 – 24 May 93. The densities correspond to 164–184 km altitude, 11°N latitude, and cover all local times.

Aeronomy of the Venus Upper Atmosphere [PDF]
Space Science Reviews, 2017 We present aeronomical observations collected using remote sensing instruments on board Venus Express, complemented with ground-based observations and numerical modeling. They are mostly based on VIRTIS and SPICAV measurements of airglow obtained in the nadir mode and at the limb above 90 km.
