IMAGE Sees Surprising Shapes in the Plasmasphere

 
 
plasmasphere

During the magnetic storms of 24 May 2000 and 29 July 2000 the IMAGE satellite saw long tails of plasma forming in the plasmasphere. Space scientists had predicted that these features would exist over 20 years ago. The dramatic movies created by IMAGE showed scientists for the first time that these shapes really did exist after all.
