A study published in Earth and Planetary Science Letters challenges a widely held assumption about the thermal state of Earth ...

“There’s more than a billion years that’s gone,” said Barra Peak, co-author of a 2021 study on this puzzling gap in Earth’s ...

Earth’s magnetic shield is shifting in dramatic ways. New data from ESA’s Swarm satellites show that the South Atlantic Anomaly — a vast weak spot in Earth’s magnetic field — has grown by nearly half ...

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 ...

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 ...

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.

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

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, ...

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

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

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

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