Dark Splotches on Venus Could Be Signs of Life

In an article from gizmodo, scientists believe that there is a possibility that microbial life may exist on Venus.  Climate models of the planet suggest that for over 2 billion years the planet was habitable but then something happened that may have caused the planet to accumulate green house gasses and become an inhospitable hellhole unfit for even microbial life.  Now thermal imaging of the planet may suggest that in the upper atmosphere there may be microscopic life that still exists.  The atmospheric pressure at the surface of the planet is about 92 times that we experience at see level here on earth and along with temperatures in the 860 degree Fahrenheit range wouldn’t even allow for microorganisms that live on volcanic geysers at the ocean bottom.  A paper from the University of Wisconsin-Madison theorizes that microorganisms can survive within the clouds on Venus due to the temperature and pressure at that altitude.  The clouds on Venus range from 48 and 52 kilometers with temperatures that range between 0-60 degrees Celsius or -32-140 degrees Fahrenheit and atmospheric pressure ranging form 0.4 to 2 atm.  The clouds are fairly acidic but researchers have found that microbes on earth can survive and even thrive in similar environments.  The article ends speculating that if we find that microbial life does exist in this cloud layer on Venus then it is quite possible for humans to find a way to live within the same area.

If this hypothesis turns out to be true then we would have conclusive proof that life on earth is not just a fluke or coincidence of nature but something that may happen in many other solar systems.  It would be as important as finding microbial life on Europa, a moon of Jupiter which is also a likely candidate for finding living organisms.  As for humans this could be another habitable planet for us to colonize at some point, possibly creating cities that resemble that of Bespin from Star Wars.  This is another scientific development that we will just have to wait and see how everything develops but it could be the first true sign that we are not alone in this universe.
