Highest energy cosmic rays are actually coming from within our owngalaxy, not from distant GRB's!

Cosmic accelerators discovered in our galaxy
"But earlier this year, physicists using the Pierre Auger Observatory in
Argentina, the world's largest cosmic ray observatory, published a
surprising discovery: Many of the energetic cosmic rays found in the
Milky Way are not actually protons but nuclei -- and the higher the
energy, the greater the nuclei-to-proton ratio."
