Space waves reveal where Earth's magnetic shield is under pressure

A new study led by researchers at the University of Oulu in Finland sheds light on a poorly understood part of space weather: where powerful waves form at the edge of Earth's magnetic shield and where the solar wind can find ...

Simulations explore nuclear mitigation of asteroid threats

Lawrence Livermore National Laboratory (LLNL) researchers are developing three-dimensional simulations to examine how a nuclear device could be used to deflect or potentially disrupt an asteroid threatening Earth.
