- There has been very little analysis of Venusian surface material, so it is possible that evidence of past life, if it ever existed, could be found with a probe capable of enduring Venus's current extreme surface conditions. However, the resurfacing of the planet in the past 500 million years means that it is unlikely that ancient surface rocks remain, especially those containing the mineral tremolite which, theoretically, could have encased some biosignatures.

- Did Venus ever host life? Big questions are often asked when thinking about other planets: Is there life? WAS there ever life? If so, what sort of life?
- How did Venus and Earth come to be so different? Venus and Earth are similar in size and density, so hypothetically, these planets could be very similar.
- How did Venus form? Even this seemingly basic question about the origin of Venus is still a mystery. “It’s amazing to me that we don’t know whether Venus formed from the same early solar system materials as did Earth and Mars,” says Getty.
- What is the atmospheric composition at Venus? The atmospheric composition of Venus is an important piece of the context we are seeking as we aim to better evaluate Venus’ potential habitability over time.
Jul 28, 2023 · Did life exist on Venus in the past? Because liquid water is the key to life as we know it, if Venus had water on its surface for billions of years it’s possible that microbial life emerged during that time. We don’t know for sure, though, and looking for evidence of past life on Venus is almost impossible with current technologies.
The possibility of life on Venus is a subject of interest in astrobiology due to Venus' proximity and similarities to Earth. To date, no definitive evidence has been found of past or present life there. In the early 1960s, studies conducted via spacecraft demonstrated that the current Venusian environment is extreme compared to Earth's.

Oct 26, 2023 · To date, we have no evidence of any past life on Venus, mostly because Venus suffered a tragic calamity. We’re not exactly sure when this disaster struck.
Oct 28, 2023 · It's possible that once —billions of years ago— Venus had life on it. The rocky planet is a "scorching wasteland" according to scientists, but long ago a shift in its tectonic...

Feb 11, 2024 · If the phosphine in the atmosphere of Earth can only be created through life, is the same true on Venus? Encouraged by the results of their first observation, Greaves and her colleagues wasted no time to observe the Venusian atmosphere again with a more advanced telescope in March 2019.
