Possibility of life on a planet like Venus is beyond imagination as the present temperature on the scorching planet is 462 degrees Celsius or 863 degrees Fahrenheit. But according to a study presented at the European Planetary Science Congress and the American Astronomical Society’s Division of Planetary Science (EPSC-DPS) Joint Meeting 2019, the planet could have liquid water on its surface. Not only this, the study claims that the planet maintained a habitable environment for 2-3 billion years after it came into existence. The study, which took place from September 15 to September 20 in Geneva, Switzerland, says that the near-global resurfacing event might be the reason behind the planet becoming the hellish hot-house as we see it today. And this significant but unwanted transformation could have begun 700 million years ago.
Author Michael Way and Anthony Del Genio of the NASA Goddard Institute for Space Science (GISS) said in a statement that their research is based on a series of five computer simulations that considered the environment on the hot planet that would have led to the conditions we see today. The study took into account the fact that the radiation from the Sun gradually increased because it became warmer over the course of the period. At present, Venus has almost twice the solar radiation that we have on the blue planet.
Way and Del Genio found that all five simulations indicated that Venus would have been able to keep steady temperatures from 68 degrees Fahrenheit or 20 degrees Celsius to 122 degrees Fahrenheit or 50 degrees Celsius. The planet maintained this temperature for almost three billion years. It is hypothesized that the drastic changes in the temperature of Venus were mainly due to change in its atmosphere. Scientists believe that large scale outgassing could have resulted in the destruction of the planet which eventually turned in to an inhabitable zone. So the research challenges the traditional view of scientists that life never existed on planet Venus.
