University of Hong Kong scientists: ancient Martian lakes are more numerous than we thought

University of Hong Kong scientists: ancient Martian lakes are more numerous than we thought  After an extensive examination by a research team from the University of Hong Kong, it was found that scientists may have significantly reduced the number of ancient lakes on Mars, which will affect future studies of the nature of the Red Planet and plans to search for ancient life remains on its surface.  To arrive at their findings, which were published in the journal Nature Astronomy, the researchers performed a comprehensive meta-analysis of studies that examined Martian lakes before.  Meta -analysis means the process of applying statistical mechanisms in order to examine the results of several studies that may be compatible or contradictory to each other.  This type of scientific mechanism is useful in generalizing the results to a larger number of samples subject to experiments, as well as in improving the accuracy of those results and better linking them to hypotheses, and of course in preventing bias for a particular experiment.  The researchers found that there are approximately 500 ancient lakes that scientists have studied before on Mars, but almost all of them are larger than 100 square kilometers.  According to the study, 70% of the lakes of the planet Earth are smaller than this area, and accordingly the researchers assumed that it is also possible for Mars that at least 70% of the lakes are small in size and have not yet been discovered.  Life's secret In addition, the research paper indicates that most of the known Martian lakes date back to a period between 3500 to 4000 million years ago, but the water remained in a geologically short period, from only 10,000 to 100,000 years.  According to an official press release issued by the University of Hong Kong on September 16, researchers used this information to conclude that Mars may have been cold and dry ancient as well, but during intermittent periods of time its temperature rose and water ran on its surface.  The statement adds that due to the low gravity on Mars, the lakes were very dark, and therefore may not have allowed light to penetrate deeply into them, and it is possible that this affected photos of life that lives on photosynthesis.  Lakes also contain water, nutrients, and other energy sources that allow bacteria and microbes to thrive and thrive, and thus scientists believe that microscopic forms of life that were found on Mars billions of years ago lived in lakes like the ones in the study.  For this reason, NASA chose the Jezero Crater to land the Perseverance rover on Mars last February, because it is believed that this area was once flooded and was home to an ancient river delta.
