NASA scientists have determined that a primitive ocean on Mars held more water than Earth's Arctic Ocean and that the Red Planet has lost 87 percent of that water to space.

Mars may have once hosted an ocean with waves that lapped against sandy beaches 3.6 billion years ago, according to new research. China’s Zhurong rover and its ground-penetrating radar detected ...

Water has been detected on Mars that could harbour life 12 miles beneath the surface, according to new research.

The new images by the Curiosity rover on Mars show "dramatic evidence" of ancient groundwater in crisscrossing low ridges, ...

Mars may be drenched beneath its surface, with enough water hiding in the cracks of underground rocks to form a global ocean, new research suggests. The findings released Monday are based on ...

Enough water to cover the surface of Mars has been discovered within the crust of the Red Planet by NASA's InSight mission. The ocean is buried between one and two kilometers (0.62 and 1.24 miles ...

New research suggests Mars could have enough water under its surface to form a global ocean. On Monday, scientists released their findings, which are based on seismic measurements captured from ...

The rise of the largest volcanoes in the solar system may have led Mars to possess oceans hundreds of millions of years earlier than previously thought, a new study finds.

Mars may be around 140 million miles away from Earth, but the red planet is influencing our deep oceans by helping drive “giant whirlpools,” according to new research. Scientists analyzed ...
