Why Astronomers Think A Poisonous Gas On Venus Could Suggest Life On This Deadly Planet.

The surface of Venus is one of the least habitable places in the solar system but astronomers studying the planet have found a chemical in the upper atmosphere which they've been unable to explain by regular chemical processes.
This is a long way from proof that life exists on Venus, but, the astronomers have worked hard over the last 3 years to rule out more mundane explanations.
I won't be surprised if someone else finds a less exciting explanation, but equally, I wouldn't be entirely unsurprised if life found a way to persist in the atmosphere of Venus and remains there today.
