A new study suggests the most extreme solar storms to strike Earth could have greater impacts on satellites, power grids and communications than previously thought.

A new NASA-led study challenges decades of scientific belief, suggesting Earth may respond more intensely to powerful solar storms than previously thought.

A new study suggests the most extreme solar storms to strike Earth could have greater impacts on satellites, power grids and communications than previously thought.

New research led by NASA Goddard found persistent “erroneous measurements” skewing past estimates for how severe geomagnetic storms can get.
