AbstractThe exploration of the Universe has fascinated the human being since ancient times. This exploration has been carried on mainly with the observation of the light, that is photons, arriving to the Earth from extraterrestrial sources. The improvement of our knowledge in particle physics as well as the big advances in the development of our experimental techniques are allowing us to extend our Universe exploration to the most energetic phenomena. For instance, photons exceeding 10 TeV have been observed with current detectors, leading to the discovery of sources without counterpart in other wavelengths. Apart from photons, cosmic rays reaching the Earth can also bring us important knowledge improving our understanding of the Universe. Cosmic rays bombard our atmosphere continuously from the space with energies up to 10^20 eV. Presently, we have measured quite well the cosmic ray energy spectrum but, almost one hundred years after its discovery, their origin is still unknown. However, recent observations of very high-energy cosmic rays have started to clear up this mystery. Correlation of the most energetic cosmic rays (> 10^18 eV) with nearby extragalactic Active Galactic Nuclei (AGN) has been observed. Both, cosmic rays and photons, will complement each other in the exploration of the Universe, in what has been called "multi-messenger approach".
