The next ‘unthinkable’ – global disruption from a solar storm
... southward, in the opposite direction to Earth’s fields, the effects can be dramatic - the whole shape of the Earth’s magnetosphere can change! NASAIt is important to remember that the impact of not listening to advice from scientists can bring...

Lessons from the Sun
... between the leading shock and the CME still-to-arrive, packed an extraordinary punch. Currents coupling the magnetosphere to Earth’s high latitude regions surged, inducing currents in long conductors at Earth’s surface. Power grids extending from...

High-energy theory models questioned as neutron star produces most energetic pulsed emission radiation ever detected
... motion of charges, forcing them to rotate at the same rate as the stellar surface. This region, called the magnetosphere, also generates intense electric fields that tear electrons from the surface, sending a stream of subatomic particles...
