- 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.
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.
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.
Aug 10, 2016 · Observations suggest Venus may have had water oceans in its distant past. A land-ocean pattern like that above was used in a climate model to show how storm clouds could have shielded ancient Venus from strong sunlight and made the planet habitable.
- Contrary to its name, Venus is a hellish place. Venus is named after the Roman goddess of love and fertility, and before the space age, the perception of the planet was driven by science fiction.
- Venus is still geologically active. The low number of craters on Venus indicates that geologic processes may be recycling aged landscapes into pockets of fresh ground.
- Nasty clouds populate its crushing atmosphere. Venus has a dense atmosphere. When the Venera 4 probe descended through that gassy sheath in the mid-1960s, it measured the composition to be primarily carbon dioxide.
- Venus twirls in a different direction. Almost all planets in our solar system, Earth included, spin counterclockwise on their axes. Venus is the only oddball that pirouettes clockwise.
Jun 30, 2021 · The amount of water in the atmosphere of Venus is so low that even the most drought-tolerant of Earth’s microbes wouldn’t be able to survive there, a new study has found.

Nov 6, 2023 · Venus, a scorching wasteland of a planet according to scientists, may have once had tectonic plate movements similar to those believed to have occurred on early Earth, a new study found. The finding sets up tantalizing scenarios regarding the possibility of early life on Venus, its evolutionary past, and the history of the solar system.
