Of course, that’s gone now. In a paper published in Geophysical Research Letters, researchers were able to make the Venus of old come alive by using climate modelling software to reconstruct the Venus of the past. Instead of a world surrounded by a thick, toxic fog that inhibits the planet with scorch
