Scientists say the most habitable zone on Mars would be a few miles below Earth’s surface, and that lifelessness was made possible by the melting of thick ice sheets due to landless heat.
Speaking about the study, Lujendra Oza, a lead author and assistant professor in the Department of Earth and Planetary Sciences at Rutgers University’s School of Arts and Sciences, said that even if greenhouse gases are pumped into the initial mercury like carbon dioxide and water vapor. In an environment of computer simulation, weather models still struggle to support long-term hot and humid Mars. He added that the concept of a young sun paradox could be partially resolved if Mars had more underground heat four billion years ago.
According to Study authors, The sun is like a giant nuclear fusion reactor that combines hydrogen with helium to produce energy. Over the centuries, it will gradually brighten and warm the surface of the planets in our solar system. However, about four billion years ago, it was very agile and therefore the atmosphere of early Mars must have been cold.
However, the surface of Mars has both geographical and chemical indicators, indicating abundant fluids about 1.1 billion to 7.7 billion years ago. This dichotomy between the geological record and the climate-based one is the young sun paradox.
Scientists examined the datasets of Mars to see if the area could be heated by geothermal heat and found that the conditions required for the melting of the crust on ancient Mars. According to him, even if Mars had a hot and humid atmosphere about four billion years ago, liquid water could only freeze at very ths depths due to magnetic field damage, atmospheric thinning and a drop in global temperature.
Thus, scientists believe that even if life originated on Mars, it would have followed liquid water to great depths.
The results of the study were published in the journal Science progress.
