Scientists have long sought to explain a key mismatch in Earth's early history: oxygen-producing photosynthesis evolved ...

Illustration of Fe(II)-enhanced phosphate adsorption onto phyllosilicates in Archean iron-rich oceans, a process that may have limited marine ...

Water is all around us; it’s the mighty oceans and Great Lakes, tiny vernal ponds and rain falling from the sky. It’s the thirst quenching liquid in your glass. Our planet is the only one we know of ...

A new study led by researchers at the Earth-Life Science Institute (ELSI) at Institute of Science Tokyo challenges a long-standing assumption about Earth's most extreme ice ages. Using numerical ...

A strip of cool water stretches west from South America along the equator, helping set the pace for some of the planet’s most important weather swings. That Pacific “cold tongue” helps steer the El ...

Over 600 million years ago, most of Earth completely froze over, becoming “Snowball Earth.” But even during this frigid period, the climate still behaved in familiar ways, earth scientist Chloe ...

The Earth’s core might not be what we once thought. Credit: Argonne National Laboratory. Earth’s core has often been described as just a giant ball of iron and nickel. Now, a new study argues that it ...

Scientists have developed a powerful new way to trace the journey of water across the planet by reading tiny atomic clues hidden inside it. Slightly heavier versions of hydrogen and oxygen, called ...

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 making it ...

Gaseous water has been detected in the planet-forming disk surrounding the star V883 Orionis (ALMA) using the Atacama Large Millimeter/submillimeter Array. The discovery "supports the idea that water ...

The Earth Dynamics Geodetic Explorer (EDGE) is one of two missions NASA selected Feb. 5 for its Earth System Explorer program. Credit: Lanteris Space Systems WASHINGTON — NASA has selected two Earth ...

A new study has revealed that the iconic Black Beauty meteorite contains much more hidden water than previously suspected. The rock, which fell to Earth from Mars, could reveal clues about the Red ...
