The researchers say they have found evidence of three new lakes on the red planet, in addition to the discovery of lakes in 2018. It is reported that this discovery benefited from the data provided by the Mars Express detector of ESA, and the relevant research report has been published in nature astronomy. < / P > < p > although most scientists believe that there may be water under the surface of Mars, it is only in recent years that science seems to have confirmed this conjecture. The latest study reports that three hidden lakes were found around the main lakes reported in 2018. These findings address doubts about the accuracy of the original report. < / P > < p > it is understood that the study in 2018 reported possible lakes based on the data of 29 observations, but the new study cited a larger scale of 134 observations as the basis for the discovery. In addition to the discovery of three new lakes, the researchers said they confirmed the presence of major underground lakes reported a few years ago. < / P > < p > the researchers used radar data collected by Mars Express from 2012 to 2019. Planetary scientist Elena pettinelli, co-author of the study, explained that the lakes were a complex system. According to radar data, the liquid water level is more than half a mile below the surface ice on Mars, which is invisible to the naked eye. < / P > < p > although they are part of the same system, the lakes are not small – the study found that these lakes together cover about one fifth of Germany’s territory. The largest of these lakes is at the center of the system, more than 18.6 miles in diameter, while the other three smaller lakes are just a few miles wide.
