NASA mission uncovers a dance of electrons in space

You can't see them, but swarms of electrons are buzzing through the magnetic environment--the magnetosphere--around Earth. The electrons spiral and dive around the planet in a complex dance dictated by the magnetic and electric fields. When they penetrate into the magnetosphere close enough to Earth, the high-energy electrons can damage satellites in orbit and trigger auroras. Scientists with NASA's Magnetospheric Multiscale, or MMS, mission study the electrons' dynamics to better understand the...
