How does a black hole generate a magnetic field and how can it be measured and visualized? Alan CroftSeattle, Washington As ...

Researchers studying a distant spiral galaxy have found that large-scale, ordered magnetic fields existed far earlier in cosmic history than standard theories predicted, forcing a fresh look at how ...

Numerical simulations provide a mechanism that explains how celestial objects such as stars and galaxies can generate ordered, macroscopic magnetic fields. The mechanism arises from turbulence — ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's happening. Two of our best ways of measuring the cosmic expansion rate, the ...

Primordial magnetic fields may help explain why measurements of the universe’s expansion do not agree. Scientists have long known that the universe is expanding, yet there is still no agreement on how ...

The new miniaturized structure requires a few thousand times less power than larger magnets and it could help bring ...

Physicists at the University of Warsaw have generated a miniature “laser tornado” inside nanoscale structures by engineering ...
