Interplanetary shocks create killer electrons
Date: 11 March 2010
Data from Cluster, and other spacecraft monitoring the magnetosphere, have shown that interplanetary shocks - caused by coronal mass ejections from the Sun - can create "killer electrons" in the near-Earth space environment within 15 minutes of the shock reaching the Earth's protective magnetic bubble. Killer electrons are highly energetic particles trapped in the Earth's outer radiation belt.
