Researchers in the United States have found the true source of a magnetic effect, ...

Researchers have identified a period of sluggish magnetic field flipping for planet Earth, some 40 million years ago – raising big questions about how long these reversals actually take, and how we ...

Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.

Scientists at the U.S. Naval Research Laboratory (NRL) have identified the true source of a magnetic effect seen in the ...

The blobs lie at the base of Earth’s mantle, around 1,802 miles beneath Africa and the Pacific.

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t pose a threat to life Earth’s magnetic field surrounds the planet, with ...

Enceladus’s geysers power vast electromagnetic wave systems that redistribute energy throughout Saturn’s magnetosphere.

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

From ancient compasses to modern smartphones, magnetometers have quietly shaped how we sense and navigate the world. Let us explore the fundamentals behind these field-detecting devices. Magnetic ...

Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields from the Big Bang may offer a solution.
