Data obtained by Saturn explorer brings mysteries of galactic cosmic ray closer

The Cassini spacecraft, which is a Saturn exploration project conducted jointly by NASA, ESA, and the Italian Space Agency, successfully observed in detail strong shock waves generated by a collision of solar winds with Saturn’s magnetosphere. Through data analysis, new information was obtained about how high energy particles were generated in our Galaxy. This research achievement was led by JAXA researchers, and the thesis has been published in “Nature Physics,�Ean online version of the British science magazine, issued on Feb. 17, 2013.
