A whole world was baffled by a recent study claiming that life could exist on Venus despite the extremely harsh conditions from the planet: surface temperatures high enough to melt lead, overwhelming atmospheric pressure, sulphuric acid rains, and so on. The presence of the toxic gas known as phosphine within the atmosphere of Venus is the main hint that there could be some aliens living on the planet.
The phosphine gas is created on Earth only by microorganisms, which leads to the idea that the same thing could happen on Venus. Of course, microbial life is way beneath those little green men that we’ve all seen in sci-fi movies, but finding any sort of life on another planet would be a tremendous step forward for science. Last but not least, the ultimate question emerges: how could life develop itself in such a harsh environment like the one from Venus?
Aliens appeared when Venus wasn’t hot
Two researchers from the University of New South Wales Sydney reveal in an essay that any aliens that could exist on our neighboring planet began to live when Venus was far from the hellish environment that we know today. Although the work represents pretty much only speculations, it presents some reliable ideas.
The models predict that Venus used to be more like Earth, with liquid water on the surface and much more friendly weather. Therefore, life must have emerged in this gentle environment and later found a way to adapt to harsher conditions.
There are two large scientific theories that explain how life might have started on Earth: the primordial soup and the Panspermia. They both explain how the first amino-acids were born, but they are far from providing reliable explanations for how life developed into the incredible diversity of species that we all know today.
