The space probe "Venus Express", created with the participation of Russian scientists in an atmosphere of Venusn discovered the ozone layer, similar to the ozone layer in Earth's atmosphere. This finding suggests the presence of any form of life on Venus, as some scientists believe the ozone layer on Earth was the result of microorganisms, that produce ozone. However, other scientists argue that too high a temperature on the surface of Venus preclude the existence of life forms similar to terrestrial life forms, and suggest, that ozone in the atmosphere of Venus formed by splitting of carbon dioxide molecules under the influence of solar radiation.
