Astronomers detect signs of life in Venus's atmosphere

The discovery of a rare chemical in the clouds of Venus could be a sign of life, an global team of astronomers said in a study published Monday.

The presence of phosphine remains "unexplained after exhaustive study", with "no now known abiotic production routes" in Venus's atmosphere, clouds, surface, or subsurface, according to the researchers, led by Jane Greaves, an astronomer at Cardiff University. On Earth, bacteria produce phosphine. The findings were published by Cardiff University professor Jane Greaves and her colleagues in a report in Nature Astronomy on Monday. In March 2019, scientists confirmed the discovery using a more powerful telescope in Chile. But their research was cut short by the coronavirus pandemic and the limited time Venus spends above Earth's horizon.
