The chance of life on Venus is a subject of interest in astrobiology because of its vicinity and similitudes to Earth. Until this point, no verification has been found of past or present life on Venus. Speculations have diminished fundamentally since the mid 1960s, when shuttle started concentrating in the world and obviously its current circumstance is outrageous contrasted with Earth's. In any case, there is continuous concentrate with respect to whether life might have existed on the Venusian surface before the current climatic nursery impact grabbed hold, and related concentrate regarding whether a relict biosphere could endure high in the cutting edge Venusian air.
Venus' area nearer to the Sun than Earth and the super nursery impact raising temperatures on a superficial level to almost 735 K (462 °C; 863 °F), and the environmental strain multiple times that of Earth, make water-based life as far as we might be concerned improbable on the outer layer of the planet. Nonetheless, a couple of researchers have estimated that thermoacidophilic extremophile microorganisms may exist in the mild, acidic upper layers of the Venusian atmosphere. In September 2020 exploration was distributed appearance the presence of phosphine in the planet's environment, a potential biosignature.
