Venus could be a haven for life


V University of Texas researchers Dirk Schulze-Makuch and Louis Irwin say the planet may have a surprising niche of life in its upper atmosphere, New Scientist reports.
The chemical composition of the Venus atmosphere suggests that something odd is happening there - and the answer could be bacterial life, they suggest.
The researchers found hydrogen sulphide and sulphur dioxide, gases that normally react with each other and thus are never found together unless something is producing them.
They also found carbonyl sulphide, a gas that normally only ever comes from a biological source.
"There may be non-biological ways to produce the hydrogen sulphide or carbonyl sulphide that we don't know about, but both reactions need catalysts to proceed efficiently," Dr Schulze-Makuch says.
"On earth, the most efficient catalysts are microbes."
