Researchers from MIT report that they have used a massive computer simulation to explain a mysterious phenomenon detected by space probes. Jan Egedal, an associate professor of physics at MIT, and colleagues explained the source of aurora-causing high-speed electrons in space in their study published in the February 26 edition of the journal Nature Physics. The finding could lead to a better ability to predict high-energy electron streams in space that could damage satellites. The...
