We study atmospheric escape from Venus during solar minimum conditions when 147 corotating interaction regions (CIRs) and interplanetary coronal mass ejections (ICMEs) combined impact on the planet. This is the largest study to date of the effects of stormy space weather on Venus and we show ...
On Mars, feedback between tidal surface winds and lifting of dust high in the atmosphere may contribute to the generation of planet encircling dust storms (Leovy et al., 1973), while breaking of tides may be important for mixing atmospheric constituents. On Venus, tides may be implicated in ...

While the present day surface of Venus is uninhabitable, the lower-cloud layer lies in the region of the atmosphere where pressure-temperature conditions are suitable for life (47–57 km altitude). This has led to suggestions of microbial life being a possible explanation for the existence of...
Venus, with a rotation period of 243 days, seems to reside in such a state. Titan rotates in 16 days and, according to circulation models, its Hadley cell extends to at least ∼60 latitude, a transitional regime between Venus and Earth. On the other hand, fast rotation confines the ...
atmospheric conditions on transit day may not be identical. Finally, there’s the matter of experimental skill. Experiments are not automatic, and often involve pushing instruments to their limits. Knowing how such instruments can be trusted under which conditions is a mark of experimental skill, ...
The conventional observables to identify a habitable or inhabited environment in exoplanets, such as an ocean glint or abundant atmospheric O2, will be challenging to detect with present or upcoming observatories. Here we suggest a new signature. A low c
reflectance*, emissivity and temperature. Our physical approach of atmospheric correction software provides a practical solution to this problem. It improves the analysis of series of images since ground brightness variations caused by varying illumination conditions and atmospheric influences can be ...
The atmospheres of Venus, earth, and Mars - A critical comparison The physical conditions and structures, chemical compositions, origins, and evolutions of the earth, Mars, and Venus atmospheres are compared, summarizing ... RG Prinn,B Fegley - 《Annual Review of Earth & Planetary Sciences》 ...
Recent work exploring the effect of thermal tides in the atmospheres of M-dwarf planets indicates that for high stellar insolation, an atmospheric torque may be generated that opposes tidally-induced spin synchronization, as is the case for Venus. This implies that M-dwarf planets may not ...
