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.
