Scientists using NASA's fleet of THEMIS spacecraft have discovered how radio waves produced by electrons injected into Earth's near-space environment both generate and remove high-speed "killer" ...
... energy stored within the Earth's magnetosphere is explosively released to accelerate these electrons.
THEMIS is establishing for the first time when and where substorms begin, determining how the ...
