Researchers found mounds in Chryse plan that would be evidence of erosion caused by water billions of years ago.

A team of scientists discovered that an image taken on Mars could help solve one of the greatest enigmas on the red planet: its aquatic past. The photograph, captured in the Chryse plan region, shows a series of mounds that, according to experts, would be the result of the erosion caused by the water between 4,000 and 3.8 billion years.
The study, published in the journal Nature Geoscience, argues that these mounds would be the remains of ancient highlands, worn by the action of water. The researchers used images captured by NASA orbiters and the European space agency to analyze their geology and determine their origin.

The finding could help explain the Martian dichotomy, a natural border between the plains of the northern hemisphere and the highlands of the southern hemisphere. According to scientists, the erosion caused by water could have played a key role in the formation of this geological division, which reinforces the hypothesis that Mars had a past with liquid water on its surface.
This discovery adds new evidence to the theory that water flowed in Mars in ancient times, which raises questions about the environmental conditions of the planet and its potential to have housed life.
