Event Horizon Telescope data reveal the magnetic field around M87* shifted, weakened and then flipped, defying theoretical expectations.

Primordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe.

Long before galaxies sparkled in the sky or stars took shape, invisible forces stirred in the early Universe. One of those ...

The universe's first magnetic fields may have been much weaker than we first imagined — and were roughly equivalent to the strength of the magnetic activity within the human brain, according to a new ...

This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly sure where these magnetic fields came from. But new research suggests they ...

NASA and the National Oceanic and Atmospheric Administration have launched three new missions to enhance our understanding of ...

The first image of a black hole was of M87*, the supermassive monster at the center of the enormous elliptical galaxy M87.

Electrons in a magnetic field can display striking behaviors, from the formation of discrete energy levels to the quantum ...

The field of ultrafast magnetism explores how flashes of light can manipulate a material's magnetization in trillionths of a ...

The Sun's activity is rising again after decades of decline, surprising scientists and raising concerns about space weather.

Researchers at Rice University created a soft but sturdy material that can transform in the blink of an eye when exposed to a basic handheld magnet—and then stabilize with no batteries or electricity.
