: Researchers successfully tracked a massive "discontinuity" in the middle cloud layer for 109 days. This wave-like feature, spanning over 4,000 km, is thought to be driven by zonal wind changes.
: Studies began investigating the stability of biochemicals, such as nucleic acid bases and amino acids, within the concentrated sulfuric acid environments of the clouds. 3. Geology & Volcanism Venus (2022)
: A 2022 study utilized a specialized Venus-ESD chamber to simulate lightning in the cloud layer, successfully characterizing 15 types of free radicals and excited atoms that could exist in the Venusian atmosphere. Mission Strategy & Navigation
: Models published in 2022 revealed that Venus's "hot" oxygen corona varies significantly (by a factor of six) based on the solar cycle, explaining why it is most visible during solar maximums. 2. Astrobiology & Habitability spanning over 4
: Numerical modeling work in 2022 proposed updated chemical compositions and interior structure models, suggesting the planet's core and mantle interactions might be more Earth-like than previously thought. 4. Mission Strategy & Navigation
