NASA's Perseverance rover discovered rocks on Mars, providing new evidence the red planet was once a wet, habitable world ...

The strongest hints yet that Mars once hosted living microbes are no longer theoretical models or ambiguous chemistry. They ...

“If life ever appeared on Mars billions of years ago… chemical traces of this ancient life could still be present today for us to detect,” analytical chemist Caroline Freissinet of the French National ...

"You need so much water that we think these could be evidence of an ancient warmer and wetter climate where there was rain falling for millions of years." ...

The discovery suggests that parts of Mars may once have supported tropical-like climates, complete with heavy, sustained rainfall.

NASA’s Perseverance rover has uncovered signs of an ancient Martian shoreline, hinting at long-lasting lakes, subsurface water activity, and conditions that may once have supported life on the Red ...

NASA’s rover Perseverance spent nearly a year exploring the rim of a crater believed to have held a huge lake.

The findings potentially solve the paradox of how liquid water seems to have persisted on Mars even when the climate grew too cold.

Long before Mars turned into the frozen desert you see today, water shaped its surface in dramatic ways. Rivers cut through highlands, lakes pooled inside craters, and floods tore open canyon walls.

“The presence of liquid water [on Mars] is a broad topic that includes rains, rivers, lakes, as well as oceans,” says Ezat ...

When the Perseverance rover landed in Mars’s Jezero crater—a formation that long ago was Jezero lake—in February, 2021 it turned west. West is where the riverbeds, the deltas, the sites of ancient ...
