How Do Scientists Forecast Auroras?
Aurora forecasts combine measurements of the Sun and solar wind with models of Earth's magnetosphere. Scientists are not predicting a fixed light show at a precise stree…

What Are the Northern Lights and Why Do Auroras Happen?
Auroras occur when energetic charged particles are guided by Earth's magnetic field into the upper atmosphere, where collisions with oxygen and nitrogen produce light. T…

What Is a Tokamak?
A tokamak is a doughnut-shaped magnetic-confinement device designed to hold extremely hot plasma using strong magnetic fields so controlled nuclear fusion reactions can…

How Does a Fusion Reactor Work?
A fusion reactor aims to create a hot plasma in which light nuclei fuse, confine or compress that plasma long enough to release useful energy, then capture the energy in…
