New satellite data show Earth’s magnetic field changing fast, with a growing weak spot over the South Atlantic.

Magnetic micropillar arrays consist of tiny, vertical pin-shaped structures, arranged in a grid-like pattern. These micropillars can change their shape to a pre-programmed geometry when exposed to a ...

We are constantly immersed in magnetic fields. The Earth produces a field that envelops us. Toasters, microwaves, and all of our other appliances produce their own faint ones. All of these fields are ...

The South Atlantic Anomaly, a huge weak spot in the geomagnetic field off South America, has expanded and sprouted a lobe in ...

A star is "blooming" in the southern sky — and astronomers using a CSIRO telescope are a step closer to knowing why. An old star, IRAS 15445-5449, has begun to push out a jet of charged particles that ...
