   Oct 6, 2011 · Yet, even if there is no life on Venus, the detection of ozone there brings Venus a step closer to Earth and Mars. All three planets have an ozone layer. "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.

   What is the spectral signature of ozone on Venus?

   • Venus Express found ozone’s spectral signature in a layer 100 kilometres up in the planet’s atmosphere, at concentrations of no more than 1 per cent those found in Earth’s atmosphere. Computer models suggest that Venus’s ozone is formed when sunlight breaks up carbon dioxide molecules.

   How did Venus Express find ozone?

   • Sunlight breaks up carbon dioxide molecules in Venus’s atmosphere, freeing oxygen atoms that meet up on the planet’s cooler night side to bind into ozone molecules. Venus Express discovered the ozone molecules by looking at individual background stars through the planet’s atmosphere, a technique that yields only spotty coverage

   Why is ozone destroyed at Venus' anti-solar point?

   • The chlorine-catalysed destruction of ozone at Venus' anti-solar point may be caused by reactions very similar to those responsible for the Antarctic 'ozone hole' on Earth, highlighting once again the similarity of atmospheric processes on these two planets.

   Oct 6, 2011 · Using observations of Venus performed with an instrument on ESA's Venus Express scientists have detected, for the first time, a tenuous layer of ozone in this planet's atmosphere. Located at an altitude of about 100 km, the layer is up to a thousand times less dense than the one found, at a lower altitude, in the Earth's stratosphere, but both are dominated by very similar chemical reactions.
