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 ...
Before radio observations in the 1960s, many believed that Venus contained a lush, Earth-like environment. This was due to the planet's size and orbital radius, which suggested a fairly Earth-like situation as well as to the thick layer of clouds which prevented the surface from being seen.
CubeSat UV Experiment (CUVE) is a space mission concept to study the atmospheric processes of the planet Venus with a small satellite. Specifically, the orbiter mission would study an enigmatic ultraviolet light absorber of unknown composition situated within the planet's uppermost cloud layer that absorbs about half the solar radiation downwelling in the planet's atmosphere.
Venus is similar in size and distance from the sun when compared with Earth, and some researchers believe the planet might have even had an Earth-like climate at some point.
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.
The atmosphere of Venus is known to have undergone substantial evolution over geologic time. [5] Evidence for this includes the present remarkable contrast between Venus’ atmosphere and the Earth's: Venus has very little water, a 95% CO 2 atmosphere, a surface temperature of 750 K, and a surface pressure of 90 bar. The early Venusian ...
Researchers’ detection of two gases, phosphine and ammonia, in the clouds of Venus raises speculation about possible life forms in the planet’s atmosphere.
While this may be exciting news, Venus is still far from being a hospitable place for Earth organisms. Scientists have detected oxygen in the atmosphere of Venus Skip to main content
