“Zebra Stripes in Outer Space”:
Long-standing mystery of radiation belt signature explained
In an article recently accepted in the Journal of Geophysical Research, Dr. Solène Lejosne, post-doctoral fellow at the UC Berkeley’s Space Sciences Laboratory and Pr. Juan G. Roederer, Professor Emeritus from the Geophysical Institute of Alaska, propose a new theory to explain a feature of the Earth’s Van Allen radiation belt particles that has defied satisfactory explanation for half a century.
This feature has been given the name “zebra stripes” by space physicists because it shows up as a zebra-like pattern in energy spectrograms, Continue reading
