Molecules vital for life could survive in Venus’s acid clouds

The acid clouds surrounding Venus might not be hostile to some of life’s key molecules


Amino acids can survive in concentrated sulphuric acid similar to that found in Venus’s clouds. This doesn’t make Earth-like life more likely in these clouds, but it does open the possibility of a kind of life based on sulphuric acid instead of water.

Whether Venus’s clouds can harbour life has been hotly argued by scientists in recent years, especially after phosphine, a molecule produced predominantly by living organisms, was spotted in the planet’s…
