Washington - Saba:
A recent study from the University of Colorado has revealed new evidence suggesting that ancient Mars had an active water system similar to that on Earth, reshaping scientific understanding of the Red Planet's history.
The study suggests that about 4 billion years ago, Mars was not as dry as it is today, but rather was filled with rivers, rain, and snow, according to an analysis of its terrain and a comparison with areas in Utah, USA.
Computer models showed that a warm, wet climate best explains the presence of rivers at various elevations. Satellite images also revealed branching river networks descending from the highlands to ancient lake basins and perhaps even to a vast ocean.
Among the most striking evidence is the Jezero Crater area, currently being explored by the Perseverance rover, which reveals a river delta dating back between 4.1 and 3.7 billion years, where strong water flows occurred.
Dr. Brian Hynek, one of the participants, emphasized that these discoveries reveal an ancient Mars that was **more dynamic** than previously thought, but the study cautions that these results are not definitive, but rather a step toward a better understanding of the history of Mars' climate.
