Scientists have revealed that they have been able to show that the planet Venus contains an ozone layer in its atmosphere! This revelation means that the planet shares this distinction with our own planet and the planet Mars!! You can read more about this discovery by reading the article. "Ozone layer found on Venus" which is at the Canadian Broadcasting Corporation's news website: http://www.cbc.ca/news/technology/story/2011/10/06/science-ozone-layer-venus.html
From the article:
"Franck Montmessin, an atmospheric scientist at the Centre National de la Recherche Scientifique in France, said in a statement that researchers were actually looking for other molecules in Venus's atmosphere when they noticed the strong ozone signature in some of their plots. That prompted them to go back and search for it in other scans."
"This ozone detection tells us a lot about the circulation and the chemistry of Venus' atmosphere," says Håkan Svedhem, ESA project scientist for the Venus Express mission in a statement"
Isn't it amazing how many scientific discoveries are made by accident (as this discovery apparently was!!)??

To develop a better understanding of the purpose of an ozone layer (as it applies to the Earth) and its functioning, please visit the following websites by clicking on their links:
"The photochemical mechanisms that give rise to the ozone layer were discovered by the British physicist Sidney Chapman in 1930. Ozone in the Earth's stratosphere is created by ultraviolet light striking oxygen molecules containing two oxygen atoms (O2), splitting them into individual oxygen atoms (atomic oxygen); the atomic oxygen then combines with unbroken O2 to create ozone, O3."
Of course unless proved otherwise, this scientific finding regarding Venus possessing an ozone layer in its atmosphere tells us that there is oxygen in the atmosphere of Venus!!
