But this isn't the first such experiment proposing enormous-scale cosmic particle detectors.

I think this is what excites me most—it could be that we are seeing a new form of cosmic particle accelerator.

Using an X-ray-like process called "muon scanning," the scientists used cosmic particle detectors to identify areas that are empty or solid.

Observing these collisions can also help us answer a range of outstanding questions, such as how black holes work as cosmic particle accelerators, or whether Einstein's General Theory of Relativity is the correct description of nature.

The clinical significance of their work was later shown by Sass. In 1975, Behnke was involved with experiments on cosmic particle radiation for the Apollo program.

Air shower formation in the atmosphere. First proton collides with a particle in the air creating pions, protons and neutrons. After the primary cosmic particle has collided with the air molecule, the main part of the first interactions are pions. Also kaons and baryons may be created.

Image illustrates all three classes of the telescopes planned. CTA will look at the sky in higher energy photons than ever measured before. In fact, the cosmic particle accelerators can reach energies inaccessible to human-made accelerators like the Large Hadron Collider. CTA's unique capabilities will help us to address some of the most perplexing questions in astrophysics.

Plasmas and their embedded magnetic fields affect the formation, evolution and destiny of planets and planetary systems. The heliosphere shields the solar system from galactic cosmic radiation. Our habitable planet is shielded by its magnetic field, protecting it from solar and cosmic particle radiation and from erosion of the atmosphere by the solar wind. Planets without a shielding magnetic field, such as Mars and Venus, are exposed to those processes and evolve differently.

One of the measurement stations of EMMA experiment situated in Pyhäsalmi mine EMMA (Experiment with MultiMuon Array) is a cosmic- ray experiment taking place in CUPP and it is still partly under construction. The experiment is a joint venture of the University of Oulu, University of Jyväskylä, University of Aarhus and the Russian Academy of Sciences. EMMA is focused on studying the composition of cosmic rays in the energy above 1 PeV- range, the so-called knee region. When a primary cosmic particle collides with the atmosphere, it decays into secondary cosmic particles creating an air shower (muons, electrons, hadrons).

The Neutron star Interior Composition Explorer (NICER) is a NASA telescope on the International Space Station, designed and dedicated to the study of the extraordinary gravitational, electromagnetic, and nuclear physics environments embodied by neutron stars, exploring the exotic states of matter where density and pressure are higher than in atomic nuclei. As part of NASA's Explorers program, NICER enabled rotation-resolved spectroscopy of the thermal and non- thermal emissions of neutron stars in the soft (0.2–12 keV) X-ray band with unprecedented sensitivity, probing interior structure, the origins of dynamic phenomena, and the mechanisms that underlie the most powerful cosmic particle accelerators known. NICER achieved these goals by deploying, following the launch, and activation of X-ray timing and spectroscopy instruments. NICER was selected by NASA to proceed to formulation phase in April 2013.
