Monday, September 14, 2020 ((rezonodwes.com)) – Scientists said on Monday that they detected a gas called phosphine in the acid clouds of Venus which indicates that microbes may inhabit Earth's neighbor , which raises questions about the potential life beyond our planet.
The researchers clarified that this is not a direct detection of life on Venus. But astronomical observations have confirmed the very intriguing presence of the chemical phosphine near the tops of the acid clouds that cover the planet.
Phosphine is a simple molecule produced on Earth by bacteria and by industrial processes. It is therefore on the list of molecules – oxygen being another – considered by scientists to be potential “biosignatures” of life on Earth-sized planets whose atmosphere can be observed using telescopes.
“ For something this big, we need follow-up confirmations, we need to have a strong scientific debate ,” said Casey Dreier, senior space policy advisor at the Planetary Society, a nonprofit pro-space organization that was not involved in the new research. “Ultimately, we're going to need missions to Venus, and maybe even bring samples back to Earth.”
