UCLA astronomers solve mystery of vanishing electronsLos Angeles CA (SPX) Jan 31, 2012 UCLA researchers have explained the puzzling disappearing act of energetic electrons in Earth's outer radiation belt, using data collected from a fleet of orbiting spacecraft. In a paper published Jan. 29 in the advance online edition of the journal Nature Physics, the team shows that the missing electrons are swept away from the planet by a tide of solar wind particles during periods of heightened solar activity. "This is an important milestone in understanding Earth's space environment," s ... read more |
