Scientists in the United States have created a small device that produces a tiny electrical signal from Earth’s natural rotation. Although the voltage is extremely small, the experiment shows that ...

A Kyoto University team has discovered that magnetic field geometry inside massive stars can either slow or accelerate their rotation in the final stages before collapse. Using 3D magnetohydrodynamic ...

Saturn’s magnetic field isn’t the smooth, symmetrical shield scientists see around Earth. Instead, it’s noticeably skewed, and researchers now think they understand why. By analyzing years of data ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...
