- 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.
Mar 28, 2024 · Called the Venus Life Finder, this mission will send a spacecraft named Photon to fly past Venus and drop a small, single-instrument probe into the planet's atmosphere.
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.
Jul 29, 2024 · Four years ago, the unexpected discovery in the clouds of Venus of a gas that on Earth signifies life — phosphine — faced controversy, earning rebukes in subsequent observations that failed to...
Nov 6, 2023 · Simulations produced by a Brown-led research team offer evidence that Venus once had plate tectonics — a finding that opens the door for the possibility of early life on the planet and insights into its history.

Sep 14, 2020 · Astronomers at MIT, Cardiff University, and elsewhere may have observed signs of life in the atmosphere of Venus. If the evidence, indicating the presence of the molecule phosphine, is indeed associated with life, it must be some sort of “aerial” life-form in Venus’ clouds.
