Scientists have found new clues that water once flowed on Mars, helping us better understand the planet's past. Using advanced tools, a rover has uncovered hidden signs beneath the surface that point to an ancient, water-rich environment, reported CGTN.

Using ground-penetrating radar, NASA's Perseverance rover has discovered subsurface traces of an ancient river delta on Mars-among the oldest evidence found to date-indicating that water once flowed across the planet's surface.

According to researchers, as the six-wheeled rover traversed 6.1 kilometers within Jezero Crater, it revealed geological structures lying approximately 35 meters beneath the ground.

Located in Mars's northern hemisphere, this region is believed to have once been submerged in water, hosting an ancient lake basin in the distant past.

Perseverance identified layered sediments and eroded surfaces, pointing to a delta-like environment. A delta is a large, fan-shaped sedimentary deposit formed where a river flows into a larger body of water, such as a lake.

Scientists estimate that this buried delta is approximately 3.7 to 4.2 billion years old. Given that Mars itself formed roughly 4.5 billion years ago, this delta dates back to the planet's earliest epoch.
