A recent study has revealed that far off alien worlds that are frozen, stand a greater chance of holding a more diverse and complex form of life that was considered earlier. Researchers had previously spotted seas of ice that extend as far as the equatorial regions of these extremely cold, far off ‘snowball’ planets. This, according to them had already increased the possibility of life persisting in these planets. The theory was based upon the fact that our very own Earth had gone through several similar snowball phrases after it was formed to turn to what we now see it.
The chief author of the study, Adiv Paradise, who is an astronomer as well as a physicist of the Toronto University, Canada, told that the fact that all the primitive forms of life on Earth formed in the oceans is enough proof for the credibility of this theory. Paradise along with his colleagues had carried out a large number of computer-based 3D simulations, wherein they artificially mimicked the climate of these theoretical far off planets. They also created climates similar to that of these planets along with a wide gamut of continents configurations, a number of energy inputs, as well as the likely level of carbon dioxide.
Carbon dioxide plays a pivotal role in these simulations, as this is the one gas that traps heat and changes the climate of a planet the most. This is evident from the fact that global warming, which has become a menace is being caused by the presence of too much Carbon-di-Oxide in the atmosphere.
Again, if and when the level of CO2 is not sufficient, it can turn a planet into a snowball. Even if that happens, it does not thwart the formation of terrestrial life. The simulations did show some hints of landmasses that are habitable. It has increased the possibility of the existence of life in these planets by manifold.
