On Monday, scientists announced that they had discovered a phosphine gas in the harshly acidic clouds of Venus, suggesting that microbes may occupy the planet.
On Earth, phosphine gas is produced by microbes living in oxygen-deficient environments and is extremely toxic to people.
Phosphine was observed in the atmosphere at 20 parts-per-billion, with researchers claiming that possible non-biological causes such as volcanism, meteorites, flashes, and different forms of chemical reactions were investigated, but were not feasible.
Analysis will continue to confirm if life forms are present on the planet or find another cause for the existence of the gas.
The gas was first detected using the James Clerk Maxwell Telescope in Hawaii and confirmed using the Chilean Atacama Large Millimeter/submillimeter Array radio telescope.
Venus is enveloped in a heat-trapping, dense, toxic atmosphere, and has a surface temperature of 880 degrees Fahrenheit.
