NASA Mystery: Electron 'Superhighway' Traveling at Speed of Light Discovered Just Outside Earth's Magnetic Field
"This is a puzzling case because we're seeing energetic electrons where we don't think they should be, and no model fits them," said David Sibeck, co-author and THEMIS project scientist at NASA Goddar...
Unexpected Role Of Electrons In Creating Pulsating Auroras
Researchers have uncovered evidence for an unexpected role that electrons have in creating the dancing auroras. Thanks to a lucky conjunction of two satellites, a ground-based array of all-sky cameras...
Scientists Discover Fundamental Property Of Light – 150 Years After Maxwell
Photons have neither mass nor charge, and so behave very differently from their massive counterparts, but they do share a property, called spin, which results in remarkable geometric and topological p...
