How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion ...

Researchers have identified a potential mechanism that explains how turbulent plasma can produce the vast, ordered magnetic fields observed across the universe Cosmic magnetic fields are everywhere, ...

The Sun’s magnetic field is invisible to our eyes, but it quietly shapes everything from the shimmering auroras over the poles to the reliability of GPS on a jet’s navigation screen. When that ...

For nearly 20 years, physicists and engineers have chased the idea of invisibility. Early efforts focused on hiding objects from light using so-called metamaterials with extreme and often unrealistic ...

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 ...

Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, however, the physical mechanisms underpinning the generation of these fields ...

Add Yahoo as a preferred source to see more of our stories on Google. Earth's magnetic field is like an invisible shield that protects our planet from solar and cosmic radiation. While it might not be ...
