I thought the question of Venus was figured out, extreme greenhouse gasses causing high temps. Not sure why the atmosphere is so acidic and near the pressure of an N2 bottle and 500 degrees C. Temperature comes from greenhouse gasses and being closer to the sun so there is more energy reaching Venus so what is left is why sulfuric acid atmosphere and the 1500+ PSI of the atmosphere.
The rest are certainly interesting and the sooner we figure ALL of those out the better off we will be, maybe I will see 150🙂 Would rather live to be 160 though, so I could say I lived in the 22nd century....
