Venus volcanism: Rate estimates from laboratory studies of sulfur gas-solid reactions [PDF]

Thermochemical reactions between sulfur-bearing gases in the atmosphere of Venus and calcium-, iron-, magnesium-, and sulfur-bearing minerals on the surface of Venus are an integral part of a hypothesized cycle of thermochemical and photochemical ...

TRAPPIST-1 d: Exo-Venus, Exo-Earth, or Exo-Dead?

The Astrophysical Journal Letters
TRAPPIST-1 d is generally assumed to be at the boundary between a Venus-like world and an Earth-like world, although recently published works on TRAPPIST-1 b and c raise concerns that TRAPPIST-1 d may be similarly devoid of a substantial atmosphere ...

Near-infrared oxygen airglow from the Venus nightside [PDF]

Groundbased imaging and spectroscopic observations of Venus reveal intense near-infrared oxygen airglow emission from the upper atmosphere and provide new constraints on the oxygen photochemistry and dynamics near the mesopause (approximately 100 km ...

Is OSSO a Significant Contributor to the Unknown UV Absorber in Venus' Atmosphere?

Geophysical Research Letters
It has been proposed that two isomers of the SO dimer (cis‐ and trans‐OSSO) are candidates for the unknown UV absorber in Venus' atmosphere because they have a good spectral match with the absorber, despite the low concentrations predicted by 1D ...

Evidence for lightning on Venus [PDF]

Lightning is an interesting phenomenon both for atmospheric and ionospheric science. At the Earth lightning is generated in regions where there is strong convection. Lightning also requires the generation of large charge-separation electric fields.

Planetary Waves Drive Horizontal Variations in Trace Species in the Venus Deep Atmosphere

The Planetary Science Journal
The deep atmosphere of Venus remains mysterious because of the planet’s high, optically thick cloud decks. While phenomena such as the observed decadal fluctuations in sulfur dioxide abundance above the clouds could shed light on conditions below, poor ...
