New Evidence of Potential Biosignatures in Venus' Atmosphere

Scientists detect phosphine and tentatively ammonia, raising questions about the possibility of life in Venus' clouds.

Overview

Researchers have re-detected phosphine in Venus' atmosphere using the James Clerk Maxwell Telescope.
A second team has tentatively identified ammonia, another potential biosignature, in the planet's clouds.
Both gases are associated with biological processes on Earth, but their presence on Venus is not yet definitive proof of life.
The findings were presented at the National Astronomy Meeting in the UK, sparking renewed interest in Venusian exploration.
Future missions, including those by NASA and the European Space Agency, aim to provide more conclusive evidence.
