The early Earth during the Hadean eon is believed by most scientists to have had a Venus-like atmosphere, with roughly 100 bar of CO 2 and a surface temperature of 230 °C, and possibly even sulfuric acid clouds, until about 4.0 billion years ago, by which time plate tectonics were in full force and together with the early water oceans, removed ...
Re-analysis of the in situ data gathered by Pioneer Venus Multiprobe in 1978 has also revealed the presence of phosphine and its dissociation products in the atmosphere of Venus. [41] In 2021, a further analysis detected trace amounts of ethane , hydrogen sulfide, nitrite , nitrate , hydrogen cyanide , and possibly ammonia .
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.
Studies have proven that Venus needed liquid water three billion years ago to be able to have such high concentrations of water-related minerals and gases on its surface and in its atmosphere today. However, such studies proved that the liquids would only have lasted up until 700 million to 750 million years ago, before eventually evaporating ...
“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 ...
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 ...
The heat builds as they descend through the Venusian atmosphere. Lars has to deal with mutiny and they find out that Lars Fuchs is Van Humphries' real father. At the end of the novel the intense heat, Lars's and Van's health and volcanic activity conspire to produce a climactic finale, in which a sulfur-based lifeform is revealed to exist on Venus.
