“It is possible that the near-global resurfacing event is responsible for its transformation from an Earth-like climate to the hellish hot-house we see today.
“Our models show that there is a real possibility that Venus could have been habitable and radically different from the Venus we see today.
“This opens up all kinds of implications for exoplanets found in what is called the ‘Venus Zone’, which may in fact host liquid water and temperate climates.”
Soon after its formation, at approximately 4.2 billion years ago, Venus would have completed a period of rapid cooling and carbon-dioxide would have prevailed in its atmosphere.
If Venus evolved in an Earth-like way over the next 3 billion years, the carbon dioxide would have been drawn down by rocks, locking it into the surface.
