The telescope observed the ice giant for a full rotation, revealing how temperature and charged particles vary with altitude.

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

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 ...

The National High Magnetic Field Laboratory welcomed nearly 8,000 visitors to explore cutting-edge scientific equipment usually reserved for researchers.

Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, ...

New observations show a small Saturn moon has generated electromagnetic waves that extend more than 313,000 miles behind it inside Saturn’s magnetic field. That newly measured reach reveals a tiny icy ...

Roughly 42,000 years ago, Earth’s magnetic field weakened dramatically during the Laschamps geomagnetic excursion, allowing more cosmic radiation to reach the atmosphere. In a peer‑reviewed study of ...

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

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.
