Abstract: I will discuss some recent cosmic rays puzzles in the context of high energy astrophysics and astrobiology and hence this talk will be divided into two parts. In the first part, I will review briefly the observational status of the ultra high energy, extragalactic part of the cosmic-ray spectrum and the interpretation of the “dipole” anisotropy, the first anisotropy signal to pass the 5 sigma discovery threshold, and review the possible extragalactic sources yet to be discovered with future multi-messenger efforts. In the second part of my talk, I will present the connection between Galactic cosmic-rays and astrobiology and discuss the possible role of spin-polarized muons in the emergence of life - more specifically, in the emergence of biological homochirality - and show the implications for the search of life in other worlds.
