The investigations of Venus take a special position in planetary researches. It was just the atmosphere of Venus where first measurements in situ were carried out by means of the equipment delivered by a space probe (Venera 4, 1967). Venus appeared to be the first neighbor planet whose ...

Although Venus is a terrestrial planet similar to Earth, its atmospheric circulation is much different and poorly characterized1. Winds at the cloud top have been measured predominantly on the dayside. Prominent poleward drifts have been observed with dayside cloud tracking and interpreted to be cause...
Sagan believes that before the earth's resources are completely exhausted it will be possible to change the atmosphere of Venus (金星) and so create a new world almost as large as earth itself. The difficulty is that Venus is much hotter than the earth and there is only a tiny amount of...

Knowing the abundances of the noble gases may allow us to answer the question why Venus did not evolve to a potentially habitable planet like its neighbour Earth. This paper presents a meta-study of existing observations of Venus' upper atmosphere and exosphere and an exospheric model of the ...

Venus Express has shown that the polar vortices of Venus are among the most variable in the Solar System. This series of images of Venus' south pole was taken with the VIRTIS instrument from February 2007 (top left) to April 2008 (bottom right). ...
