NASA's Curiosity rover took advantage of a clear winter day to snap new panoramic pictures of one of Mars' most enduring ...

There might be a hidden ocean's worth of liquid water below the surface of Mars, seismic evidence suggests. According to a new paper published April 25 in the journal National Science Review, ...

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 the ...

Seismic data collected by NASA suggests the amount of water hidden in the red planet's crust would cover its surface in a global ocean. Evidence is mounting that a secret lies beneath the dusty red ...

A hypothetical picture of Mars 3.6 billion years ago, when an ocean may have covered nearly half the planet. The blue areas show the depth of the ocean filled to the shoreline level of the ancient, ...

PHOENIX — This week’s landmark announcement that the surface of Mars has liquid water links back to a University of Arizona laboratory where students and faculty monitor images from an orbiting camera ...

Frigid water helped paint Mars red and may have shaped a vast coastline, two new studies into the planet’s history reveal. Scientists have detected a possible ancient beach in Mars’ northern ...

After years of hunting for a lost ocean on Mars, a planetary scientist at UC Berkeley and others have finally dug up compelling evidence. The surface of Mars today is a mostly dry, frigid wasteland.

For years, scientists have been looking for signs of liquid water just beneath the surface of Mars. The problem, though, is that the observations from various orbiting probes have been maddeningly ...

A NASA satellite has spotted frozen "kidney beans" on Mars' sand dunes trapped in place until springtime. Photographing them can help us determine if there was ever enough water on Mars to sustain ...
