“In plots of the habitable zone, you typically see Venus on the outside,” he said. “And for modern day Venus, that’s certainly true. But, if you have a Venus-like world around a solar-type star with a slow rotation, it could be quite a reasonable place for life to exist, especially in the oceans.”
A past-habitable Venus also opens up new possibilities about the origin of life on Earth. From meteorites, we know that Earth and Mars were swapping material in the distant past, prompting astrobiologists to wonder whether the Red Planet could have seeded our world with life. But if life was just as likely to emerge on Venus, that’s one more planet to add to mix. Incredibly, we don’t know whether there are any meteorites from Venus here on Earth, because we’ve never been able to analyze a rock on Venus for comparison.
Until then, we can’t deny the possibility that our distant ancestors were actually born on that torrid acid bath next door. “It could be that life got started on Venus, and then seeded Earth,” Way said. “Or vice-versa.”
