Until the mid-20th century, the surface environment of Venus was believed to be similar to Earth, hence it was widely believed that Venus could harbor life. In 1870, the British astronomer Richard A. Proctor said the existence of life on Venus was impossible near its equator, [11] but possible near its poles.
Today's Venus can be described as hellish: there is almost no water vapor, the carbon dioxide atmosphere is 90 times as thick as that on Earth and temperatures can reach a scorching 864 degrees.
Even though Venus is violently hostile to life, the planet is so similar to our own in makeup and location that it's often referred to as Earth's twin Venus may once have been habitable. Now it ...
Venus is a hellhole. Despite being much closer to Earth than Mars, its climate is off-the-charts insane, with average temperatures of 864 degrees F, crushing barometric pressure, and did I mention ...
Studies have proven that Venus needed liquid water three billion years ago to be able to have such high concentrations of water-related minerals and gases on its surface and in its atmosphere today. However, such studies proved that the liquids would only have lasted up until 700 million to 750 million years ago, before eventually evaporating ...
Although the surface conditions on Venus are no longer hospitable to any terrestrial-like life that might have formed before this event, there is speculation that life may exist in the upper cloud layers of Venus, 50 km (30 mi) above the surface, where atmospheric conditions are the most Earth-like in the Solar System, [106] with temperatures ...
Astronomers have found a potential sign of life high in the atmosphere of neighboring Venus.
Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
