Abstract

Abstract: Ultra high energy cosmic rays are the highest-energy particles ever observed in nature. Although known for more than half a century, their origin is still baffling scientists. They are most likely linked to some of the most violent phenomena in the universe but the nature of their sources remains a mystery, and so does the physical mechanism to accelerate particles to extreme energies. Here we review the different aspects of ultrahigh energy cosmic rays, emphasizing the key achievements over the past decade in our understanding of their origin. We also give a brief account of upcoming experiments and the prospects of progress in this field of research.
