Recent discoveries have unveiled the existence of hidden caves on Mars, raising intriguing questions about the potential for ...

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, ...

Until recently, Mars was studied only through telescopes and some data that was recorded from early spacecraft. It was thought that Mars' polar regions were the only significant reservoirs of ice, ...

For years, scientists have been intrigued by mysterious dark streaks running down the slopes of Martian cliffs and craters. These marks, called slope streaks and recurring slope lineae (RSLs), have ...

A new study from NYU Abu Dhabi has found that high-energy particles from space, known as cosmic rays, could create the energy needed to support life underground on planets and moons in our solar ...

Prevailing theories suggest that Mars was once covered in a major liquid water system of oceans, rivers, and lakes, which presupposes a thick atmosphere that could maintain temperatures at which ...

NASA plans to send humans on a scientific round trip to Mars potentially as early as 2035. The trip will take about six to seven months each way and will cover up to 250 million miles (402 million ...

The Martian surface presents a complex record of geological processes that have spanned billions of years. The planet’s topography reveals evidence of volcanic activity, impact cratering, fluvial ...

One of the great unsolved problems in modern planetary science is written on the surface of Mars. Mars has canyons that were carved by rivers, so it was once warm enough for liquid water. How—and ...
