Like the Earth and Mars, Venus has an ozone layer, European scientists have discovered.
An ozone layer a hundred to a thousand times less dense than Earth's sits at about an altitude of 100 kilometres above the surface of Venus and is five to 10 kilometres thick, the European Space Agency reported in a news release Thursday.
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.
