The probability of life on Mars was below the surface: study

WASHINGTON: If life ever existed on ancient Mars, it would be several miles below the surface of the Red Planet due to the melting of the subsurface of deep ice sheets due to geothermal heat, according to a definitive study. ۔
The study, published in the journal Science Advances, looked at various datasets on Mars to determine whether geothermal or underground heating was possible between 4.1 billion and 3.7 billion years ago or in the Neolithic period.
He showed that the conditions required for the melting of the earth’s surface were carried out everywhere on ancient Mars.
Even if Mars had a hot and humid climate 4 billion years ago, with the disappearance of the magnetic field, the atmosphere becoming thinner and the subsequent decrease in global temperature over time, the researchers found that perhaps Liquid water can be stable at considerable depths.
“So, life,” he said, “if it ever started on Mars, it could go deeper slowly after liquid water.”
“At such depths, life could be revived by hydrothermal activity and the reaction of rocks to water. Therefore, this source surface could represent the longest habitable environment on Mars,” said Rutgers University. Assistant Professor, Lead Author Lujender Ojha said. New Brunswick in the United States.
From this study, young people are known as the contradictions of the sun. This is a long question in the science of Mars.
“Even if computer-generated greenhouse gases such as carbon dioxide and water vapor are pumped into the early Martian atmosphere, climate models still support long-term hot and wet Mars,” Ojha said. Struggle for. ”
“My colleagues and I suggest that if the sun goes down, at least in part, there could be peace if there had been geothermal heat in the past of Mars,” he said.
Our sun is a large-scale nuclear fusion reactor that produces energy by fusing hydrogen into helium, the researchers said.
Over time, he explained, the sun slowly brightens and warms the surface of the planets in our solar system.
According to researchers, about 44 billion years ago, the sun was so dominant that the climate of early Mars should have been frozen.
However, there are many geological signs on the surface of Mars, such as ancient river beds, and chemical signs, such as water-related minerals.
Researchers say that this suggests that the Red Planet had an abundance of liquid water during the Nuchiana period.
“This obvious contradiction between the geological record and the climate models is the contradiction of the unconscious young sun,” he said.
On rocky planets such as Mars, Earth, Venus, and Mercury, heat-generating elements such as uranium, thorium, and potassium generate heat through radiation.
In such a situation, liquid water can be produced by melting under ice sheets, even if the sun was furious.
On Earth, for example, geothermal heat forms subglacial lakes in the western Antarctic ice sheet, Greenland, and the Arctic region of Canada.
Researchers say that this could help explain the presence of cold, liquid water on Mars, which froze 4 billion years ago.
