Ordered magnetic fields spontaneously emerge out of chaotic, tangled fields. This finding is consistent with astrophysical observations. Streamlines of magnetic fields are 3D-rendered and are colored ...
The Earth's core is mostly an Fe-Ni alloy with a fraction of light elements (~10 wt%, mainly O, S and Si). Accumulation of these light elements under the core-mantle boundary (CMB) may lead to ...
A research team led by Tomoro Sashida and Tomoharu Oka of Keio University in Tokyo, Japan, has succeeded in precisely measuring the expansion velocity of a shock wave of the supernova remnant W44. The ...
