Two years ago, a team of astronomers reported the discovery of a large lake buried under a thick layer of ice on Mars' Antarctic. International scientists using ESA's Mars Express satellite have now confirmed the discovery, along with three more lakes in the same area. This is according to a quote from CBS News on Thursday afternoon, October 1, 2020.
A new study published this week in the journal Nature-Science acknowledges the discovery of lakes under the glacier 2018 and supports that discovery with the discovery of three more similar lakes at Mars Antarctic. Researchers used radar data from ESA's Mars Express spacecraft between 2012 and 2019.
Among them, the largest lake has a diameter of about 30 km. Scientists believe the water there is too salty, allowing it to remain in liquid form, even under the cold temperatures of Mars. However, such a high salt content may mean that no life form is present. The scientists hope that in the future, the mission to Mars will focus on a detailed study of the red planet's south pole related to these lakes.
According to their beliefs, there could be a network of large and old underground lakes, possibly millions or billions of years old, when Mars was as hot and humid as Earth. Currently, the surface of Mars is depressed because water can no longer be present in its upper layer due to the lack of atmospheric layers, gravity and magnetic fields.
