What are some features of Venus atmosphere?

Venus, the second planet from the Sun, has an atmosphere about 96 times thicker at the surface level than Earth. The Venus atmosphere consists of 96.5% carbon dioxide and 3.5% nitrogen, which is considered a similar atmosphere of the country approximately 4.4 billion years ago. In the case of Earth, most carbon dioxide was absorbed by the sea and was caused by carbonates, but Venus lacks surface water or biomass to sequencies carbon dioxide, so it remains in the air.

Venus can be considered an extreme example of global warming with an average surface temperature of 461.85 ° C (863 ° F). It is not only because of the proximity of Venus to the sun, but because of the "greenhouse effect" - the sun can supply heat to the atmosphere of Venus, but maintain this heat due to a large amount of greenhouse gases - carbon dioxide, sulfuric acid - present. On the ground that has an atmosphere 100 times less dense, more energy radiates.

Although the surface of Venus can be considered one of the most uninhabitable areas inner solarSystems, at approximately 50-65 km (31-40 miles) above the surface, temperature and atmosphere pressure of Venus is similar to earth temperature. Because the pressure is similar, balloons full of breathable air (21% oxygen, 78% nitrogen) would float at this level if they remain structurally intact. Not only that, but also the extremely slow rotation of the planet itself. The equatorial clouds at this level rotate around the planet about once every 20 hours. The colony would be suspended here by the wind and experienced a regular night and day, like people living on Earth. These factors have caused some scientists in space to call this region most habitable in the solar system outside the country, exceeding Mars.

Because the planet lacks its own magnetic field, Venus' the atmosphere is constantly attacked by the solar wind. The charged solar wind strips from hydrogen, helium and oxygen atoms that produce a long magnetotail composed of ions spread many planetary averages behind Venus.

The atmosphere of Venus is fullSulfuric acid clouds that reflect 75% of incoming light. Historically, their many layers were used to cover the surface of Venus, and humanity had speculated about the world under. Nothing was known about the surface of Venus until the 1970s, when the radar pulses on the planet were lit by 300 m radio telescope in the Arecibo observatory. This revealed surface features up to 5 km (3 miles) in width.
