Note that the meridional circulation is much lower than the zonal circulation, which transports heat between the day and night sides of the planet. All winds on Venus are ultimately driven by convection. [3] Hot air rises in the equatorial zone, where solar heating is concentrated and flows to the poles.
The main problem with Venus today, from a terraformation standpoint, is the very thick carbon dioxide atmosphere. The ground level pressure of Venus is 9.2 MPa (91 atm; 1,330 psi). This also, through the greenhouse effect, causes the temperature on the surface to be several hundred degrees too hot for any significant organisms.
This heat is transferred to the gas in contact with the surface, both greenhouse, and non-greenhouse. Then the atmosphere is warmed by convection. This allows heat to be retained through the night, etc. Why Venus is so hot is one of the outstanding mysteries of science, so I obviously can't give you a fully satisfactory answer.
The EnVision Venus explorer will study that planet in unprecedented detail, from inner core to the top of its atmosphere, to help astronomers understand why the hot, toxic world didn’t turn out ...
Venus' oceans may have boiled away in a runaway greenhouse effect. A runaway greenhouse effect involving carbon dioxide and water vapor likely occurred on Venus. [22] In this scenario, early Venus may have had a global ocean if the outgoing thermal radiation was below the Simpson–Nakajima limit but above the moist greenhouse limit. [2]
Venus is a primary feature of the night sky, and so has been of remarkable importance in mythology, astrology and fiction throughout history and in different cultures. The eight-pointed star a symbol used in some cultures for Venus, and sometimes combined into a star and crescent arrangement.
Throughout December, Venus will move higher and higher in the night sky, setting several hours after the sun. Because of how bright Venus will appear, some are referring to it as this year's ...
