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.
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.
The possibility of life on Venus is a subject of interest in astrobiology due to Venus' proximity and similarities to Earth. To date, no definitive evidence has been found of past or present life there. In the early 1960s, studies conducted via spacecraft demonstrated that
Today's Venus can be described as hellish: there is almost no water vapor, the carbon dioxide atmosphere is 90 times as thick as that on Earth and temperatures can reach a scorching 864 degrees.
The reason for this is that when Venus is closest to Earth, it is between the Earth and the Sun, so we see only its night side. Indeed, even when Venus is brightest in the Earth's sky, we are actually seeing only a narrow crescent. For a Mercurian observer, on the other hand, Venus is closest when it is in opposition to the Sun and is showing ...
If proponents of Gaia theory are to be believed, a major reason for the water on Earth is due to the abundant presence of life. Indeed, all living things capable of aerobic respiration produce water as a matter of discourse. Venus and Mars, on the other hand, have atmospheres relatively close to their equilibrium states (Mars more so than Venus).
Mars is located 142,000,000 miles away from the Sun. Named after the Roman God of war, Mars is widely known for its blood-red color. Chinese astronomers even used to call Mars the 'fire star ...
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 ...
