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.

For the origination factor, there are two possibilities for how life emerged on Venus: It either arose on its own from nonliving matter or was transported there from elsewhere. That Venus is thought to have once had a similar climate to Earth, replete with a watery ocean, opens up the possibility that life could have begun there independently. Yet ...
If life did take hold on Venus, the second factor, robustness, assesses whether the quantity and variety of life was substantial enough to withstand dramatic shifts in climate. Earth is the measuring stick for robustness because not only is it the only planet known to contain living organisms, but it also contained enough sheer biomass and diversit...
The third and final factor in the Venus Life Equation captures the necessity of an unbroken continuity of habitat from the origination of life up to the present. It is the factor that poses the greatest uncertainty because so little is known still about the planet’s geologic past and its chemical makeup. One key question is whether there was any or...
Jan 5, 2021 · The LIP analogues on Venus include individual volcanoes that are up to 500 kilometres across, extensive lava channels that reach up to 7,000 kilometres long, and there are also associated rift ...
Oct 13, 2021 · While Earth is a natural hub for life, Venus is a lifeless planet with a toxic carbon dioxide atmosphere 90 times thicker than ours, clouds of sulphuric acid and surface temperatures that reach ...
Sep 24, 2021 · Venus, our vexing sister planet, was likely habitable up to 900 million years after its formation, all without the need for plate tectonics (the global geological recycling of a planet’s carbon ...
Jul 28, 2023 · At the surface, Venus has average temperatures of 470 degrees Celsius (878 degrees Fahrenheit) — hot enough to melt lead. Venus is so hot because of its thick carbon dioxide atmosphere, which traps heat creating a runaway greenhouse effect. Fifty-four times more dense than Earth’s, it is the densest terrestrial atmosphere in the Solar System.

Apr 29, 2021 · The new radar measurements show that an average day on Venus lasts 243.0226 Earth days — roughly two-thirds of an Earth year. What’s more, the rotation rate of Venus is always changing: A value measured at one time will be a bit larger or smaller than a previous value. The team estimated the length of a day from each of the individual ...
