The magnetized rocks of Earth's crust and mantle, also known as the upper lithosphere, accounts for generating 6 percent of ...

Who knew that magnetic fields could be so useful? Astronomers are able to use magnetic fields to map our environment within the Milky Way using a technique called Faraday rotation. It works like ...

Figures of merit: the MFC2046 NMR magnetic-field camera provides field measurements with a resolution of 10 ppb and sub-mm positioning tolerances. (Courtesy: Metrolab) Measurement speed aside, one of ...

The magnetic field that surrounds our planet is constantly shifting. But lately, near the Arctic, it’s been so active that researchers had to release a crucial update to the World Magnetic Model ...

Instead of focusing on sensor readings at specific points, their magnetoreceptor captures electrical resistance information ...

If the magnetic field they detected extends to the surface of the black hole, it would be sufficient to explain the entire spectrum of emissions from the Milky Way's center.

With a unique new all-sky map, scientists have made significant progress toward measuring the magnetic field structure of the Milky Way in unprecedented detail. Specifically, the map is of a ...

That perpetual updating was smoother sailing once airplanes could capture magnetic-field data. Today, the task largely falls (up) to satellites, whose readings feed into the World Magnetic Model ...

But mapping the strength of the magnetic fields that largely control that behavior has proved elusive. The fields are weak and the brightness of the sun outshines its corona.

“Global mapping of the coronal magnetic field has been a big missing part in the study of the Sun,” Zihao Yang, a study co-author from Peking University in China and a postdoctoral fellow at ...

Home / Mars’ Patchwork Magnetic Field Acts As Array Of Umbrellas To Protect Planet’s Atmosphere, according to new mapping study by Mars Global Surveyor, acco ...

Their compass is the sun, the stars and the Earth's magnetic field. But their map is a little more mysterious. One theory goes that they use olfactory cues—how a place smells.
