They're all around us: sensors and satellites, radars and drones. These tools form vast remote sensing networks that collect data on the climate, the ground, the air, and the water. This information ...

Earth's cosmic neighbourhood is more dynamic than imagined, hosting temporary 'mini-moons' captured by gravity and ...

Several studies have predicted that not all geomagnetic reversals have been discovered, but it was unknown in which periods they might be hidden. Researchers led by the National Institute of Polar ...

Scientists at Stanford have unveiled the first-ever global map of rare earthquakes that rumble deep within Earth’s mantle rather than its crust. Long debated and notoriously difficult to confirm, ...

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

Sometimes the geologic record obscures evidence of these important reversals in field direction, but statistical techniques ...

Even when Earth was locked in its most extreme deep freeze, the planet’s climate may not have been as silent and still as ...

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

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

Sediments from Scotland hint that ocean-atmosphere interactions continued more than 600 million years ago despite widespread ice.

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

On Jan. 31, 1958, Explorer 1 became the first satellite launched by the United States. Its primary science instrument, a ...
