Interstellar space is made up of stray atoms, molecules and microscopic dust particles. Cosmic rays are made up of protons, alpha particles, electrons and gamma rays. Dark matter makes up 27% of the universe and cannot be detected and dark energy makes up 68% of the universe and cannot be detected either.
