New research suggests that Mars had done in turn of warm and cold rounds billions of years ago. These ups and downs at relatively low intervals may affect the planet’s ability to maintain liquid water. Conclusions indicate that when Mars was ever a wet world, heavy temperature changes could affect any possible life forms. Scientists continued to find out how the atmosphere of Mars retained the warmth despite the distance of the planet from the lower brightness of the Sun and the Sun during its early history.
Studies highlights martian climate variability
according to a Study Published in Nature Geosines, Harvard John A. Researchers at the Paulson School of Engineering and Applied Sciences (CILs) investigated how Mars’s climate developed. Hydrogen is believed to have played an important role in trapping heat in the planet’s atmosphere, preventing surface water from cold. This hydrogen, interacting with carbon dioxide, produced a greenhouse effect similar to the earth. However, hydrogen levels should have been short -lived, to tell scientists how the atmospheric position changed over time.
Hot period and their influence on the atmosphere of Mars
Danica Adams, NASA Sagan PostDoATORAL Fellow, as stated, Explained A statement that his findings suggest that Mars experienced episodic warm period between four to three billion years ago. These temperatures raised up to at least 100,000 years and were repeated over a period of 40 million years. The loss of water from the atmosphere to the surface is considered to recreate hydrogen, which maintains the greenhouse effect for a short period.
Chemical reactions and atmospheric changes
Chemical changes were also seen, in which carbon dioxide broke into carbon monoxide under sunlight. During the warm period, this carbon monoxide returned to carbon dioxide, which helped maintain the warming cycle. If the cold condition persists, carbon monoxide and oxygen will accumulate, which will change the structure of the environment.
Analysis of future of martian samples
Robin Wordsworth, a seize researcher, reported that the study integrates atmospheric chemistry with climate model to make predictions that can be tested after returning the martian rock samples to Earth. Scientists hope that further analysis will provide deep insight into the past of Mars and whether the conditions to support microbial life were ever stable.
