The upper atmosphere of Venus can be measured from Earth when the planet crosses the sun in a rare event known as a solar transit. The last solar transit of Venus occurred in 2012. Using quantitative astronomical spectroscopy, scientists were able to analyze sunlight that passed through the planet's atmosphere to reveal chemicals within it.
Although there is little possibility of existing life near the surface of Venus, the altitudes about 50 km (31 mi) above the surface have a mild temperature, and hence there are still some opinions in favor of such a possibility in the atmosphere of Venus. [35] [36] The idea was first brought forward by German physicist Heinz Haber in 1950. [37]
At 5 km (3.1 mi) higher, it is a temperate 27 °C (300 K; 81 °F) (see Atmosphere of Venus § Troposphere). The atmosphere also provides the various elements required for human life and agriculture: carbon, hydrogen, oxygen, nitrogen, and sulfur. [5] Additionally, the upper atmosphere could provide protection from harmful solar radiation ...
Its thick and noxious atmosphere is dominated by carbon dioxide - 96.5% - with lesser amounts of nitrogen and trace gases. In fact, with Venus getting far less scientific attention than other ...
Venus is one seriously hot planet, but it appears that is not its only claim to fame. ...
The initial observations of Venus' super rotation were Earth-based. Modern GCM models and observations are often enhanced by looking at past ancient climates. In a model where Venus is assumed to have an atmospheric mass similar to Earth, SS-AS circulation could have dominated over super-rotation in an ancient thinner atmosphere. [2]
Venus is the second planet from the Sun.It is a terrestrial planet and is the closest in mass and size to its orbital neighbour Earth.Venus has by far the densest atmosphere of the terrestrial planets, composed mostly of carbon dioxide with a thick, global sulfuric acid cloud cover.
“Life, uh… finds a way.” Except maybe not in the clouds of Venus. Sure, our sister planet makes Dante’s vision of Hell look like a tropical paradise. I mean, a greenhouse-driven surface ...
