From a half-million miles away, NASA's Europa Clipper spacecraft captured Mars with its two moons, Phobos and Deimos, in ...

Life doesn’t always need sunlight. In fact, in some of the coldest, darkest places in the solar system, the spark for life might come from something far more extreme: cosmic rays. A new study led by ...

Water has been detected on Mars that could harbour life 12 miles beneath the surface, according to new research. Seismic data from Nasa’s Insight lander indicates deep, porous rock filled with ...

CAPE CANAVERAL, Fla. — 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 ...

The Mars ocean theory hatched in the 1970s after spacecraft imagery showed an apparent large shoreline and seabed-like indentation. Some scientists discounted the idea since the shore seemed irregular ...

China's first Mars sample-return mission, Tianwen-3, is scheduled for launch around 2028, with the goal of returning no less ...

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 ...

The “Mars ocean theory” has long been the topic of discussion among scientists and cartographers due to Mars’s geography, which suggests a large northern ocean once existed on its surface.

Scientists also think, at least some of the ocean must have disappeared underground. Data from NASA's Insight lander recently found enough water to cover Mars with an ocean between one and two ...
