Atmosphere of Venus

The atmosphere of Venus is the layer of gases surrounding Venus. It is composed primarily of supercritical carbon dioxide and is much denser and hotter than that of Earth. The temperature at the surface is 740 K, and the pressure is 93 bar, roughly the pressure found 900 m underwater on Earth. The Venusian atmosphere supports opaque clouds of sulfuric acid, making optical Earth-based and orbital observation of the surface impossible. Information about the topography has been obtained exclusively by radar imaging. Aside from carbon dioxide, the other main component is nitrogen. Other chemical compounds are present only in trace amounts. Aside from the very surface layers, the atmosphere is in a state of vigorous circulation. The upper layer of troposphere exhibits a phenomenon of super-rotation, in which the atmosphere circles the planet in just four Earth days, much faster than the planet's sidereal day of 243 days.

SOFIA Fails to Find Phosphine in the Atmosphere of Venus, But the Debate Continues

Phosphine is produced by bacteria in the swamps of Earth. For some reason it's also floating around the atmosphere of Venus. 2 years ago this discovery led to skepticism, but after multiple confirmations, 6 spacecraft are now scheduled to visit "the forgotten planet" for the first time in 30 years.
