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.
