Signs of two gases in clouds of Venus could indicate life, scientists say

Separate teams find evidence of phosphine and ammonia, potential biomarkers on planet whose surface reaches 450C

Hot enough to melt metal and blanketed by a toxic, crushing atmosphere, Venus ranks among the most hostile locations in the solar system. But astronomers have reported the detection of two gases that could point to the presence of life forms lurking in the Venusian clouds.

Findings presented at the national astronomy meeting in Hull on Wednesday bolster evidence for a pungent gas, phosphine, whose presence on Venus has been fiercely disputed.
