To date, no definitive proof has been found of past or present life on Venus. ... With extreme surface temperatures reaching nearly 735 K (462 °C; 863 °F) and an atmospheric pressure 90 times that of Earth, the conditions on Venus make water-based life as we know it unlikely on the surface of the planet.

Can Venus ever be habitable?

Incredibly, however, is that early in Venus' history, the planet may have actually been habitable, according to models from researchers at NASA's Goddard Institute for Space Studies and other studies. Venus' surface is extremely dry.

When could Venus have been habitable?

Drastic climate shifts 700 million years ago made the planet's atmosphere incredibly dense and hot. The hellish planet Venus may have had a perfectly habitable environment for 2 to 3 billion years after the planet formed, suggesting life would have had ample time to emerge there, according to a new study.
