From a Japanese satellite, researchers measured these factors from a point near the Earth: Then they tracked the particles to The Pas, Man., where an all-sky camera had captured images of the resulting pulsating aurora. The researchers obtained the data with the help of the Canadian Space Agency. Satoshi Kasahara, the University of Tokyo planetary scientist who led the study, and his colleagues compared the data from Earth and from space. They confirmed that pulsating auroras are generated when clumps of plasma waves in the magnetosphere, the region of space affected by the Earth's magnetic field, intermittently herd and shove aurora-causing [Read more]
