In many rivers, only a small amount of streamflow remains for nature after water is diverted for hydropower production. In light of climate change and biodiversity loss, this is having increasingly serious consequences. Researchers from WSL,...
Scientists have identified what could be the oldest rocks on Earth from a rock formation in Canada. The Nuvvuagittuq Greenstone Belt has long been known for its ancient rocks—plains of streaked gray stone on the eastern shore...

Could habitable planets orbiting white dwarfs retain their oceans? Maybe

Potentially habitable exoplanets are so incredibly common that astronomers have started to consider more unusual situations where life might arise. Perhaps life can be...

Uranus’s swaying moons could help spacecraft seek out hidden oceans

When NASA's Voyager 2 flew by Uranus in 1986, it captured grainy photographs of large ice-covered moons. Now nearly 40 years later, NASA plans...

How did magma oceans evolve on early Earth and Mars? Iron chemistry and primordial atmospheres offer clues

Before Earth became the blue planet, it was engulfed by a very different kind of ocean: a vast, deep magma ocean reaching down hundreds...

Study explains how Enceladus ejects particles from oceans beneath its surface

Although it is relatively small, Enceladus—the sixth largest of Saturn's 83 moons—has been considered by astronomers to be one of the more compelling bodies...

Magnetic oceans and electric Earth

Oceans might not be thought of as magnetic, but they make a tiny contribution to our planet’s protective magnetic shield. Remarkably, ESA’s Swarm satellites...

How Mars lost its oceans

It has long been known that Mars once had oceans due in part to a protective magnetic field similar to Earth's. However, the magnetic...
