2. Atmosphere of Venus - Wikipedia

   en.wikipedia.org/wiki/Atmosphere_of_Venus

   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 ...

   Researchers’ detection of two gases, phosphine and ammonia, in the clouds of Venus raises speculation about possible life forms in the planet’s atmosphere.

4. Scientists detect oxygen in noxious atmosphere of Venus - AOL

   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 ...

5. Atmospheric super-rotation - Wikipedia

   en.wikipedia.org/wiki/Atmospheric_super-rotation

   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]

6. Water on terrestrial planets of the Solar System - Wikipedia

   en.wikipedia.org/wiki/Water_on_terrestrial...

   The current Venusian atmosphere has only ~200 mg/kg H 2 O(g) in its atmosphere and the pressure and temperature regime makes water unstable on its surface. Nevertheless, assuming that early Venus's H 2 O had a ratio between deuterium (heavy hydrogen, 2H) and hydrogen (1H) similar to Earth's Vienna Standard Mean Ocean Water of 1.6×10 −4, [7] the current D/H ratio in the Venusian atmosphere ...

   Photo Illustration by Elizabeth Brockway/The Daily Beast/NASAVenus is a nasty planet. Thick layers of high-pressure, sulfuric clouds cover a very hot volcanic surface, which can rise up to as high ...

8. Runaway greenhouse effect - Wikipedia

   en.wikipedia.org/wiki/Runaway_greenhouse_effect

   Venus-like conditions on Earth require a large long-term forcing that is unlikely to occur until the sun brightens by some tens of percents, which will take a few billion years. [7] Earth is expected to experience a runaway greenhouse effect "in about 2 billion years as solar luminosity increases".

9. It’s getting harder for life in Venus’ atmosphere to exist

   “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 ...
