Astronomers see possible hints of life in Venus's clouds

Astronomers have found a potential sign of life high in the atmosphere of neighboring Venus: hints there may be bizarre microbes living in the sulfuric acid-laden clouds of the hothouse planet. Two telescopes in Hawaii and Chile spotted in the thick Venusian clouds the chemical signature of phosphine, a noxious gas that on Earth is only associated with life, according to a study in Monday’s journal Nature Astronomy.
