Because Venus is completely covered in clouds, human knowledge of surface conditions was largely speculative until the space probe era. 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.
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.
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 ...
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 ...
Astronomers have found a potential sign of life high in the atmosphere of neighboring Venus.
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.
Venus imaged in different wavelengths by spacecraft. The planet Venus was first observed in antiquity, and continued with telescopic observations, and then by visiting spacecraft. Spacecraft have performed multiple flybys, orbits, and landings on the planet, including balloon probes that floated in its atmosphere. Study of the planet is aided ...
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 ...
