The hottest planet in our solar system, Venus, has shown possible signs of life. It is covered with dense clouds of acid and has recorded a surface temperature above 475 degrees Celsius or 900 degrees Fahrenheit. And now, Dr. Michelle Thaller, a research scientist at NASA's Goddard Space Flight Centre, has proposed a theory of possible signs of life on Venus. According to the unconventional claims of Dr Thaller, the conditions where human life is rendered impossible show signs of alien life hiding somewhere on the cloudy planet.
The atmosphere of Venus shows certain signs that can only be produced if any bacteria reside on the planet. Dr Thaller believes that there are possible signs of life in the carbon dioxide-filled atmosphere and has stated that she is certain about the existence of life somewhere. Due to its similar structure and size to Earth, Venus has been given the moniker "Twin of Earth." Yet, it is impossible for humans to survive on this planet.
However, Professor Dominic Papineau- an astrobiologist at the University College of London, has expressed skepticism about the theory and suggested other potential sites for extraterrestrial life.
Professor Papineau feels that Dr. Thaller's views are difficult to ascertain. The Professor believes that for such life-related chemical reactions to take place, liquid water is necessary. To find extraterrestrial life, one needs to discover fossils that might have been driven deep into the sedimentary rocks containing the history of life-sustaining liquids.
Professor Papineau said that it is challenging to hypothesize how Venus would sustain life, given its problem with widespread volcanism that appears to cover most of the surface for the past 100 million years.
However, both Dr. Thaller and Professor Papineau agree that microbial life could be found on icy moons within our solar system. NASA says we have 290 traditional moons, which does not include 464 small asteroids and minor planets.
Professor Papineau also mentioned that the possibility of extraterrestrial life and fossils on Mars and icy moons is higher than on Venus. Ice has been found on the Martian south poles. Geological records also indicate that Mars and icy moons preserve fossils.
