Scientists To Explore Possibility Of Life In Venus' Clouds.

The clouds of Venus may host alien life according to scientists who suggest that microbes may now have evolved on the planet. Some models also suggest that  Venus once had a habitable and liveable climate with liquid water on its surface for whopping two billion years.
That period is much longer than is believed to have occurred on Planet Mars, said Sanjay Limaye from the University of Wisconsin-Madison in the US.

On Planet Earth, terrestrial microorganisms, mostly bacteria are capable of being swept into the atmosphere where they have been found alive at altitudes at a height as high as 41 kilometres by scientists who used specially equipped balloons, according to David J Smith from NASA's Ames Research Center.

There’s also a growing catalogue of microbes known to inhabit incredibly harsh environments on our planet also including the hot springs of Yellowstone, the deep ocean hydrothermal vents, the toxic sludge of polluted places and in acidic lakes found in different parts of the World.

According to Rakesh Mogul who is a professor at California State Polytechnic University in the US, on Earth as we all know that life can thrive in very acidic conditions, it can feed on carbon dioxide and produce sulphuric acid.
The cloudy, acidic and highly reflective atmosphere of Venus consists of and is composed mostly of carbon dioxide along with water droplets that contain sulphuric acid.
The team of scientists believes this could make Venus vital in the search for various other life forms, but what we need to do first is the the planets’ clouds to be sampled and tested.

The Spectroscopic observations, in ultraviolet show that the dark patches are composed of concentrated sulphuric acid as well as other unknown light absorbing particles, these dark patches have been a mystery since they were observed for the first time by ground-based telescopes almost a century ago, said Limaye who has led the study published in the journal named Astrobiology. 

According to Prof Limaye Venus shows episodic dark and sulphuric rich patches which persist for days, changing their shapes and contrasts on a continuous basis and also appear to be scale dependent.The particles that make up these dark patches almost have the same dimensions like some bacteria on Planet Earth, the patches could be something similar to the algae blooms that happen routinely in lakes and oceans of Earth, according to researchers.
But according to Mogul in order to really know, we need to go there and sample the clouds as Venus could be an exciting new chapter in astrobiology exploration also.
