Aliens' Frozen World More Likely Than Thought to Support Life and Diversity

For the first time, a new study suggests that alien worlds that are frozen may have more diverse and complex forms of life than previously thought. Previously, scientists had discovered ice oceans that reach all the way to the equator on these far-off, extremely cold “snowball” worlds. It had already boosted the chances of life on these worlds, according to the scientists. Earth has gone through a number of comparable snowball phases after it was formed to become the planet we see today.

Physicist and astronomer Adiv Paradise led the study, and he said that evidence for the validity of this idea comes from the fact that all of Earth’s earliest forms of life originated in the oceans. In a series of computer-based 3D simulations, Paradise and his colleagues have attempted to artificially imitate the climates of hypothetical planets in deep space. A wide range of continent shapes as well as a variety of sources of energy were also included in their models, as well as the expected quantity of carbon dioxide.

Carbon dioxide is a critical component in these models since it is the most effective greenhouse gas for trapping heat and altering the temperature of a planet. Carbon-di-Oxide, which has become a major contributor to global warming, can be seen as a clear example of this.

A planet could become a snowball if the quantity of CO2 is not sufficient. No matter what happens, there will still be life on Earth. There were some hints of livable landmasses in the simulations. It has enhanced the likelihood of life on these worlds by a factor of tens of thousands.
