A collaborative study led by Professor Vittoria Raffa at the University of Pisa and Assistant Professor Fabian Raudzus ...

Science X is a network of high quality websites with most complete and comprehensive daily coverage of the full sweep of ...

Earth’s magnetic field strength and atmospheric oxygen levels have oscillated in tandem for around 540 million years, according to a NASA-led study, pointing to a deep-Earth process that could knit ...

It's a gradual transition from a dipole to a complex magnetic field, to a reversed dipole over the entire 11-year solar cycle. "In short, there is no specific 'moment' in which the sun's poles ...

Scientists are learning more about how common magnetic fields are around planets and moons. One of Earth's defining features is its magnetic field. It forms a protective shield against high-energy ...

The Voyager spacecraft measured that Uranus and Neptune have nondipolar magnetic fields while strong dipole fields had been expected. Stanley and Bloxham thus proposed that the magnetic fields be ...

Determination of the magnetic dipole moment of a spacecraft is a key issue for magnetic cleanliness and attitude control of various space scientific spacecraft. Two main methods, namely the multiple ...

Consistent with the magnetic dipole field approximations assumed in the diffusion coefficients themselves, the Jacobian is given by the dipole formula G = p2T (α0) sin (α0) cos (α0), where the ...

After #51 is done and we have the gravity gradient components in spherical coordinates, the magnetic fields of dipoles in spherical coordinates would be very straight forward because the kernel ...

Earth's magnetic field originates in the outer core and extends out into the magnetosphere — a region of space that helps protect Earth from space weather.

This rover carries the Mars Surface Magnetic Field Detector, which will measure the field to an accuracy of better than 0.01 nanotesla. That’s less than a millionth of the field strength of Earth.
