The book is divided into two parts, the first describing the standard model of cosmic rays and contemporary challenges, and the second part dealing with very high energy cosmic rays that cannot be detected directly in satellite and balloon experiments, and with gamma-ray and neutrino astronomy. It is in this particular aspect of the book that the greatest developments have taken place during the 5 years since the first edition was completed. Consequently, it is in the chapters cosmic ray showers, their spectrum, on high energy neutrinos, and on gamma-ray astronomy of this revised and updated 2nd edition that a considerable amount of new material has been incorporated with more minor revisions and updating taking place in the first part of the book. Students and lecturers of advanced undergraduate courses on cosmic rays and astroparticle physics as well as post graduates and researchers will continue to find this book a valuable source of learning and reference.
