HEXDC6 Cosmic rays.Artwork of high-energy particles radiation from star in deep space (cosmic rays) impacting molecules atoms in Earth's atmosphere.These primary impacts cause secondary cascade of subatomic particles.Detection analysis of these particles,which include protons,neutrons,light nuclei,neutrinos,pions,and muons,can reveal source of cosmic rays.These sources may include gamma ray bursts (GRBs),active galactic nuclei,supernovae quasars.Such research is carried out atmospheric balloons,or advanced detectors built underground or underwater,to shield them from other radiation.

US Navy is developing GPS that uses cosmic rays to navigate the Arctic

At higher latitudes, traditional GPS navigation is not reliable, but muons produced when cosmic rays hit Earth’s atmosphere could be used to navigate in the Arctic, as well as underground or in the water
