It transports far more than 100 times as much water as all of the Earth's rivers combined: The Antarctic Circumpolar Current ...

A colossal ocean current encircling Antarctica—stronger than all the world’s rivers combined—played a far more complex role in shaping Earth’s climate than scientists once thought. New research shows ...

Water, the cradle of life as we understand it, is no longer unique to Earth. From subsurface oceans on frozen moons to water vapor in extraterrestrial atmospheres, NASA's findings are redefining what ...

Scientists launch a global mission to explore 10,000 deep ocean locations and uncover unseen marine life and ecosystems ...

When we look at Earth from space today, we see a pale blue dot—a planet dominated by vast oceans that shimmer under the sunlight. But what if our oceans weren't always blue? According to recent ...

(CNN) — Picture all of Earth’s oceans, which cover about 70% of the planet and are mostly made of hydrogen. Now multiply that by nine. That may be the amount of hydrogen in Earth’s core, possibly ...

Meteor impacts may have helped spark life on Earth, creating hot, chemical-rich environments where the first living cells ...

The deep blue sea may not have always been so blue. A new study suggests that the Earth's oceans may have changed color over time and could change again in the future, depending on the chemical makeup ...

We've always called Earth the blue planet, but that color might not be permanent. Previous research claims our oceans were once green, and if environmental conditions shift dramatically, a new study ...

Our species likes it cold. Homo sapiens evolved in — and still inhabits — one of Earth’s rare and fragile ice ages, periods distinguished not by an abundance of saber-toothed cats and woolly mammoths ...
