Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, ...

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

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.

Magnetic fields thread through galaxies, stretch across cosmic voids, and shape the behavior of charged particles over millions of light-years. Yet their origin remains one of the most stubborn ...

A new radio survey reveals that the Milky Way’s magnetic field is intricate, widespread, and deeply connected to how the galaxy is organized.

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

Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.

Just as the amplified magnetic field peaked, these electrons settled again, locking in the strong field’s direction. Benjamin Weiss, an MIT professor and study co-author, explains the process like ...
