In many ways Venus is found to be similar to Earth. However their similarities do not extend further than their physical properties, for instance, their atmospheres differ greatly from each other. Venus is said to have atmospheric pressure of 92.1 barometers (Adams, D. Et al., 1994 p.126) which it is evidently 92 times greater than Earth’s that is 1.01 barometers (Adams, D. Et al., 1994 p.126) at sea-level. In spite of this comparison to Earth’s atmospheric pressure, Venus owns an out of the ordinary atmospheric composition.

Once it was considered that scientific investigations of the structure of Venus was impeded by the heavy clouds that form its atmosphere, hence, for many years scientists have studied its composition and thus unveiling the clouds that hinder such analysis. Then, being familiar with the chemistry of this atmosphere would be imperative for one to understand its composition.

In order to get the latter statement a Russian spacecraft – Venera – was sent to Venus to carry out investigations. Thereupon, it was found that the Venusian atmosphere has an unusual atmospheric structure of two distinct tropospheric areas that carry out distinct chemical reactions. Such structure goes as follows: the upper troposphere is exposed to sun rays thus carries out dissociation related chemical reaction whereas the lower troposphere is protected from the solar light hence traps heat and carries out heat related chemical reactions. In conclusion, such reactions that take place together with the abundant carbon dioxide (CO2) in the Venusian troposphere are vital in order to create species such as oxides of nitrogen (NOx) and produce sulphuric acid (H2SO4) droplets that make up the clouds veiling Venus.

As said before, Venus show...

...m. From this section, it was also informed that the surface temperature in Venus is tremendously high which give its unique property of flaky crust compared to the hard solid that its sister planet has. Again, its temperature is so high that takes up all the water existent and lives no chance of life in its planet.

Interesting enough, Venus has no mountains, but yet, it has more than 80% of its plain land filled with volcanoes and lava. The craters that indentify its surface also told the reader the age of Venus. Venus is about 500 million years old (NASA. 2007), scientists learnt this by studying the deepness and consequence of debris impact in the surface of Venus.

All the properties and similarities of Venus to Earth, help scientists to unveiled the mysteries and fantastic properties of this planet and now we are able to delight ourselves with such knowledge.
