RE: “Earth orbits at the inner edge of the habitable zone”
Quite a few scientists seem to believe that Venus’ atmosphere might hold microscopic life or very buoyant life forms.
Your thoughts?
The upper atmosphere of Venus would be considerably cooler than the surface but its very dry. Hard to say what is possible.
Venus is ridiculously hot, and that mitigates against any kind of life form as we’d recognize it. Extremophiles might, possibly, live in the extreme upper atmosphere, but they’d have to be introductions, iow, not native to Venus.
There is also the possibility of micro organism life forms, in regards some of moons of the larger outer planet's in our own system, such as Saturn and Jupiter.
