A team of researchers with NASA, Uppsala University, Columbia University and the Planetary Science Institute has created several simulations of conditions on Venus billions of years ago using Earth climate models and has found some instances that suggest the planet may at one time have been capable of harboring life.

Venus is extraordinarily hot, volcanically active and has an atmosphere that is mostly carbon dioxide. But the simulations created by the research team suggest it may not have always been that way. They started with the idea that Venus and Earth were probably similar billions of years ago—a time when Earth’s atmosphere was also mostly carbon dioxide...

Rice University scientists propose that life in the solar system could have been very different – See more at: http://news.rice.edu/2016/07/05/lush-venus-searing-earth-it-could-have-happened-2/#sthash.pz2Lc0vd.dpuf

Life in the solar system could have been very different. If conditions had been just a little different an eon ago, there might be plentiful life on Venus and none on Earth. The idea isn’t so far-fetched, according to a hypothesis by Rice University scientists who published their thoughts on life-sustaining planets, the planets’ histories and the possibility of finding more...
