Supernovae, producing shock waves propagating in the interstellar medium. Highly magnetized rotating neutron stars, releasing their rotation energy as relativistic electron–positron outflows. Super massive black holes in the center of galaxies, launching relativistic jets. Gamma-ray bursts, very energetic explosions at the deaths of massive stars. Binary neutron stars, emitting gravitational waves, destined to eventually merge. Relativistic particles, accelerated in such sites. Cosmic rays, electromagnetic radiation, and neutrinos, travelling in space.
