Ozone in Venus's atmosphere

The European Space Agency's (ESA) Venus Express probe has made a very important discovery when it found a thick layer of ozone in the Venus atmosphere. Comparing the properties of this ozone layer with the Earth and Mars equivalents will help astronomers calculate the direction of life search on other planets.

Venus has the same size and volume as the earth but the conditions are much tougher, it hides under a dense cloud of toxic gases like CO ₂ , H ₂ SO ₄ . Discovery of Venus Express Helping scientists better understand the difference between Venus's development and the Earth.

The Venus Express SPICAV device analyzed the light, found the characteristic trace of gases in the atmosphere to find that ozone was present to absorb some ultraviolet rays from the starlight. Research shows that the sun breaks down the structure of CO ₂ , releases oxygen atoms and then they combine to produce O ₂ and a little O ₃ . Dr. Franck Montmessin, leader of the research team, said that we previously had very limited understanding of Venus's atmosphere.

On Earth, the ozone layer is extremely important because it shields the ultraviolet rays that are harmful to life's development. Many documents suggest that ozone formed in the earth's atmosphere about 2.4 billion years ago. It is possible that microorganisms have released oxygen to form ozone and this process is pushed more aggressively as plants grow on the earth. Through this study, cosmologists have put the problem: in an atmosphere and oxygen, carbon dioxide and ozone, it is the basis for forming life on that planet.

Mars and Venus's atmosphere has 100-1,000 times more diluted ozone than Earth and is as high as 100km, so it is not enough to shield life on these two planets.
