Where do cosmic rays, discovered more than a century ago, come from? The standard model of their origin points to natural particle accelerators in the form of shock waves in supernova remnants, but there is mounting experimental evidence that there are other sources.

Where (in energy) is the transition to an extragalactic component? What extragalactic sources are conceivable?
