For decades, scientists have suspected the presence of a magnetic field that holds the Milky Way together, but only now has ...

In addition to shaping the interior of rocky planets, molten rock located deep within these planets may also contribute to the creation of a planet’s magnetic fields, which protect the entire planet ...

From galaxies to the Sun, new research explains how turbulent motion can produce large-scale magnetic fields that remain ...

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the solar wind, high-energy particle transport, and galaxy formation. Small-scale ...

Scientists are mapping the Milky Way galaxy’s invisible magnetic field, revealing how it holds the galaxy together and ...

For desert ants, Earth’s magnetic field isn’t just a compass: It may also sculpt their brains. Stepping outside their nest for the first time, young ants need to learn how to forage. The ants train ...

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 ...

Earth’s magnetic field nearly collapsed long ago. What saved it explains why life survived and why the planet remains ...

For the first time, scientists have used satellite data to create a 3D map of the sun's interior magnetic field, the ...
