Telescopes and satellites have extensively looked at Earth's evil twin, Venus, but they have yet to observe oxygen - this goes in the face of computer simulations of the atmosphere that predict it must be there at levels high enough to detect. In the laboratory we have studied particular chemical reactions, under conditions relevant to Venus' upper atmosphere, that may hold the key to understanding why there is no observed molecular oxygen on Venus. In particular, we have investigated whether reactions between chlorine and carbon monoxide might be converting oxygen to carbon dioxide. We will show our equipment, results from our experiments, and updated computer simulations of Venus' atmosphere with our new laboratory results.
