Astroparticle physics is entering a booming era thanks to the new generation of detectors such as Fermi, AMS-02, IceCube, HAWC, and Auger. We outline recent developments in the study of the messengers of GeV-to-TeV gamma rays, Very-high-energy gamma rays, high-energy neutrinos, and ultrahigh-energy cosmic rays. Then we present a few ideas toward solving the big question of the field, that is, the origin of the astroparticles across multi-wavebands. Specifically, we focus on three approaches, namely, building theoretical models with advanced numerical simulations, fully exploiting the existing data with efficient point source search methods, and building future experiments.
