NASA announced possible evidence of present-day liquid water on Mars. Scientists analyzed data from NASA's Mars Global ...

Manga noted that lots of evidence—river channels, deltas and lake deposits, as well as water-altered rock—supports the hypothesis that water once flowed on the planet's surface. But that wet ...

Before they take the long journey to another planet, humans will have to find the right place to land. New findings from a ...

One prevailing notion holds that asteroids containing either water of its building blocks bombarded the planet. But now, a team of researchers have produced evidence that those building blocks were ...

A team of scientists estimates that there may be enough water, trapped in tiny cracks and pores of rock in the middle of the Martian crust, to fill oceans on the planet’s surface. The ...

Calculations suggest the "missing" water is enough to cover the planet in an ocean at least 700 meters deep, and perhaps up to 900 meters deep. One hypothesis has been that the missing water ...

Peering at a rocky planet 26 light-years away, the James Webb Space Telescope (JWST) has spied signs of water vapor. The discovery would mark the first time that astronomers have ever managed to ...

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 ...

Scientists announced Monday that for the first time, they've found evidence of liquid water on Mars – which they say is buried in cracks several miles under the Red Planet's surface. This is the ...

“Antarctic bottom water” is the coldest, saltiest water on the planet. These waters play a crucial role in the ocean’s ability to act as a buffer against climate change by absorbing excess ...
