ESA's Cluster Mission helps reveal how the Sun shakes the Earth's magnetic field.
Space is a hostile region for astronauts & satellites. One constituent of this hazardous environment around the Earth are very energetic electrons, able to perturb or permanently damage satellites.
Ultra Low Frequency (ULF) waves, which travel along the Earth's magnetic field lines, are a prime candidate for generating these killer electrons, but the source of these waves remains unclear.
