As much as 45 oceans’ worth of hydrogen may be in Earth’s core, scientists reported, suggesting most of Earth’s water was ...

Two new satellite missions will help NASA scientists better understand Earth and improve the ability to foresee environmental ...

They're all around us: sensors and satellites, radars and drones. These tools form vast remote sensing networks that collect ...

A new study analyzes three asteroid and two meteorite samples to see if space rocks smacking into Earth could’ve helped kickstart life.

The Earth Dynamics Geodetic Explorer (EDGE) team was one of two teams selected out of four finalists for NASA’s Earth System ...

Scientists now understand why seismic waves speed up near Earth's core. Extreme pressure and temperature cause solid mantle rock to flow slowly, aligning mineral crystals. This anisotropic structure ...

NASA has selected two Earth science missions for development, one focused on studying the atmosphere and the other on terrestrial ecosystems and ice.

Researchers studying the deep biosphere, Earth’s largest ecosystem, have found evidence that life thriving miles below the planet’s surface may have played a far bigger role in shaping atmospheric ...

Even when Earth was locked in its most extreme deep freeze, the planet’s climate may not have been as silent and still as once believed. New research from ancient Scottish rocks reveals that during ...

The Earth Dynamics Geodetic Explorer (EDGE) satellite is one of two next generation satellites selected by NASA to help ...

An experiment to quantify the amount of the universe’s lightest element in Earth’s core suggests that the planet’s water has mostly been here since the beginning ...

Life’s story may stretch further back than scientists once thought. Some genes found in nearly every organism today were already duplicated before all life shared a common ancestor. By tracking these ...
