Venusian clouds are thick and are composed mainly (75–96%) of sulfuric acid droplets. [51] These clouds obscure the surface of Venus from optical imaging, and reflect about 75% [52] of the sunlight that falls on them. [1] The geometric albedo, a common measure of reflectivity, is the highest of any planet in the Solar System.
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 upper two layers of the clouds were found to be sulfuric acid droplets, but the lower layer is probably composed of phosphoric acid solution. The crust of Venus was analyzed with the soil drill experiment and a gamma ray spectrometer. As the landers carried no cameras on board, no images were returned from the surface.
Researchers’ detection of two gases, phosphine and ammonia, in the clouds of Venus raises speculation about possible life forms in the planet’s atmosphere.
Astronomers have found a potential sign of life high in the atmosphere of neighboring Venus: hints there may be bizarre microbes living in the sulfuric acid-laden clouds of the hothouse planet.
The surface of Venus is completely covered by clouds which prevent most heat from escaping. Furthermore, water, in any form, is almost entirely absent from Venus. The atmosphere is devoid of molecular oxygen and is primarily carbon dioxide. In addition, the visible clouds are composed of corrosive sulfuric acid and sulfur dioxide vapor.
Venus, our closest planetary neighbor, is sometimes called Earth's twin based on their similar size and rocky composition. ... and a toxic atmosphere with sulfuric acid clouds. These stark ...
The atmosphere contains sulfuric acid clouds. In 1968, NASA reported that air pressure on the Venusian surface was 75 to 100 times that of Earth. [ 15 ] This was later revised to 92 bars , [ 16 ] almost 100 times that of Earth and similar to that of more than 1,000 m (3,300 ft) deep in Earth's oceans.
