Venus The Strongest Greenhouse Effect in the Solar System

“On Venus there are no day and night variations of the surface temperature. The heat is globally ‘trapped’ under the carbon-dioxide atmosphere, with pressure 90 times higher than on Earth. Instead, the main temperature variation is due to topography. Just like on Earth, mountain tops are colder, whereas the lowlands are warmer. The ‘only’ difference is that on Venus ‘cold’ means 447? Celsius, while ‘warm’ means 477? Celsius. Such high temperatures are caused by the strongest greenhouse effect found in the Solar System.” – physorg

Could life exist at such temperatures? We don’t think so. Currently, 121 degree Celsius is the hottest temperature on Earth at which life has been found to exist (a single-celled microbe from a deep-seal hydrothermal vent).
