The atmosphere of Venus is the very dense layer of gases surrounding the planet Venus. Venus's atmosphere is composed of 96.5% carbon dioxide and 3.5% nitrogen , with other chemical compounds present only in trace amounts. [ 1 ]
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 study of extraterrestrial atmospheres is an active field of research, [1] both as an aspect of astronomy and to gain insight into Earth's atmosphere. [2] In addition to Earth, many of the other astronomical objects in the Solar System have atmospheres. These include all the giant planets, as well as Mars, Venus and Titan.
Researchers’ detection of two gases, phosphine and ammonia, in the clouds of Venus raises speculation about possible life forms in the planet’s atmosphere.
The thick atmosphere on the second planet from the sun traps in heat in a runaway greenhouse effect. "Venus is not hospitable, at least for organisms we know from Earth," Hübers added.
Spacecraft have performed various flybys, orbits, and landings on Venus, including balloon probes that floated in the atmosphere of Venus. Study of the planet is aided by its relatively close proximity to the Earth, compared to other planets, but the surface of Venus is obscured by an atmosphere opaque to visible light.
Volcanism, by injecting gases into a planet's atmosphere, provides clues about the interior of rocky planets. As magma ascends from an intermediate planetary layer called the mantle to the surface ...
DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) is a planned mission for an orbiter and atmospheric probe to the planet Venus.Together with the separate VERITAS mission, which will also study Venus, it was selected by NASA on June 2, 2021 to be part of their Discovery Program.
