Water might have formed much earlier than previously thought. Computer simulations show supernovae produced significant ...

Astronomers have uncovered the largest and most distant water reservoir ever detected in the universe. This staggering ...

With an orbit of 647 days, HD 20794 d is similar to Mars in our solar system. However, its orbit around the star is highly ...

The four exoplanets orbit Barnard’s Star so closely that their years last only a few Earth days. They are probably rocky and, ...

More than 3 billion years ago, Mars intermittently had liquid water on its surface. After the planet lost much of its ...

As researchers continue to study this hidden water and its effects on the planet, we may uncover even more secrets about how ...

Rivers on Earth carve winding paths through landscapes, shaping the terrain over time. At first glance, their meandering ...

Our planet orbits 93 million miles (150,000 km) away from the sun. This puts Earth in a so-called "Goldilocks zone," where the temperature is just right for liquid water to exist on the surface.

Freshwater from melting ice sheets can slow the critical ocean circulation that helps regulate the planet’s climate ...

Research published late last year indicated “seismic discontinuities in the Martian crust” that scientists believe could be an indicator of liquid water under the Martian surface, raising the ...
