Earth’s magnetic field and rotation are producing electricity — just not how anyone expected
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 ...
No matter how its done, with whatever level of fakery, magnetic levitation just looks cool. We don’t know about you, but merely walking past the tackiest gadget shop, the displays of levitating and ...
Using the Nanshan One-meter Wide-field Telescope (NOWT), Chinese astronomers have performed multi-color photometric observations of a rapidly rotating magnetic star known as HD 345439. Results of this ...
Solar rotation, a fundamental characteristic of the sun, is second in importance only to the Schwabe cycle, an approximately 11-year cycle. The energy and matter of the solar atmosphere originate from ...
Oh, those twinkling, twinkling little stars. They make the night sky seem so peaceful, so idyllic, so quiet. It’s hard to believe that they are actually powerful furnaces, where explosive power, ...
