Cosmic ray astronomy is a branch of observational astronomy where scientists attempt to identify and study the potential sources of extremely high-energy (ranging from 1 MeV to more than 1 EeV) charged particles called cosmic rays coming from outer space.
Shower detection. A cosmic-ray observatory is a scientific installation built to detect high-energy-particles coming from space called cosmic rays.This typically includes photons (high-energy light), electrons, protons, and some heavier nuclei, as well as antimatter particles.
The SED of M51 (upper right) obtained by combining data at many different wavelengths, e.g. UV, visible, and infrared (left). A spectral energy distribution (SED) is a plot of energy versus frequency or wavelength of light (not to be confused with a 'spectrum' of flux density vs frequency or wavelength). [1]
High-energy astronomy is the study of astronomical objects that release electromagnetic radiation of highly energetic wavelengths. It includes X-ray astronomy, gamma-ray astronomy, extreme UV astronomy, neutrino astronomy, and studies of cosmic rays. The physical study of these phenomena is referred to as high-energy astrophysics. [1]
Existence of "Knee" in the energy spectrum of cosmic rays. Production and/or acceleration of highest energy (~10 20 eV) cosmic rays in the universe. Astronomy of multi-TeV γ-rays from neutron stars and other compact object. Sun the closest astrophysical object, accelerator of energetic particles and its effects on the Earth.
Zeta Reticuli, Latinized from ζ Reticuli, is a wide binary star system in the southern constellation of Reticulum. From the southern hemisphere the pair can be seen with the naked eye as a double star in very dark skies. Based upon parallax measurements, this system is located at a distance of about 39.3 light-years (12 parsecs) from Earth.

High Energy Stereoscopic System (H.E.S.S.) is a system of imaging atmospheric Cherenkov telescopes (IACTs) for the investigation of cosmic gamma rays in the photon energy range of 0.03 to 100 TeV. The acronym was chosen in honour of Victor Hess , who was the first to observe cosmic rays .
