Gas-giant planets orbiting close to other stars have powerful magnetic fields, many times stronger than our own Jupiter, according to a new study by a team of astrophysicists. It is the first time the strength of these fields has been calculated from observations.
The team, led by Wilson Cauley of the University of Colorado, also includes associate professor Evgenya Shkolnik of Arizona State University’s School of Earth and Space Expl...

Using math models, scientists have ‘looked’ into the interior of super-Earths and discovered hey may have compounds that are forbidden by the classical rules of chemistry – these substances may increase the heat transfer rate and strengthen the magnetic field on these planets. The researchers attempted to see which compounds may be formed by S, O, and Mg at high pressures. These particular elements were not chosen by chance. “Earth-like planets consist of a thin silicate crust, a silicate-oxide mantle – which makes up ~7/8 of the Earth’s volume and consists more than 90% of silicates and magnesium oxide – and an iron core. We can say that magnesium, oxygen, and silicon form the basis of chemistry on Earth and on Earth-like planets,” says Oganov...
