Variable oxygen airglow on Venus as a probe of atmospheric dynamics
Article Abstract:
New high-resolution images of Venus's atmosphere found an oxygen airglow that develops during nighttime downwelling at an altitude of about 95 kilometers. This airglow forms at the interface of two global-scale circulation patterns: an east-west super-rotation above 100 and below 70 kilometers in altitude and a solar-locked circulation between these heights. The oxygen atoms, which result from photolysis of CO2, yield radiation that generates the airglow.

Implications of the high D/H ratio for the sources of water in Venus' atmosphere
Article Abstract:
The atmosphere of Venus contains an abundant ratio of deuterium to hydrogen. This indicates that either comets or volcanic outgassing continuously supply water to the surface of Venus, or the presence of a lost primordial ocean. The D/H ratio of the source water on Venus is 10 to 15 times higher than on earth. A highly fractionated mantle source could result in continuous outgassing.

The four final rotation states of Venus
Article Abstract:
It has been shown that terrestrial planets with dense atmosphere, such as Venus, can evolve into one of only four possible rotation states. This work confirms that the retrograde rotation of Venus can be explained by taking account of its dynamics.
