Piccard Cove ( ) is a cove bordered by O'Neal Point to the northwest and Sophie Cliff to the northeast, and forming the southernmost part of Wilhelmina Bay, along the west coast of Graham Land.
 Charted by the Belgian Antarctic Expedition under Gerlache, 1897-99.
 Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 for Auguste Piccard, Swiss physicist, stratosphere pioneer who reached a height of 9.5 nautical miles (18 km) in a hydrogen-filled balloon in 1931.
Kinsey Amor Anderson (September 18, 1926 – June 11, 2012) was professor emeritus of physics at the University of California at Berkeley (UCB) and an internationally known pioneer of space physics during the early years of rocket, balloon, and satellite exploration of the upper atmosphere, cosmic rays, solar-terrestrial environment, and solar physics.
Cosmic rays are high-energy radiation, mainly originating outside the Solar System and even from distant galaxies.
 Upon impact with the Earth's atmosphere, cosmic rays can produce showers of secondary particles that sometimes reach the surface.
 Composed primarily of high-energy protons and atomic nuclei, they are of mysterious origin.
 Data from the Fermi Space Telescope (2013) have been interpreted as evidence that a significant fraction of primary cosmic rays originate from the supernova explosions of stars.
 Active galactic nuclei probably also produce cosmic rays.
Explorer 6, or S-2, was an American satellite launched on August 7, 1959.
 It was a small, spheroidal satellite designed to study trapped radiation of various energies, galactic cosmic rays, geomagnetism, radio propagation in the upper atmosphere, and the flux of micrometeorites.
 It also tested a scanning device designed for photographing the Earth's cloud cover, and transmitted the first pictures of Earth from orbit.
Auguste Antoine Piccard (28 January 1884 – 24 March 1962) was a Swiss physicist, inventor and explorer, known for his record-breaking hot air balloon flights, with which he studied Earth's upper atmosphere and cosmic rays, and for his invention of the first bathyscaphe, "FNRS-2", with which he made a number of unmanned dives in 1948 to explore the ocean's depths.
John David Linsley (12 March 1925 – 25 September 2002) was an American physicist who performed pioneering research on cosmic rays, particularly ultra-high-energy cosmic rays.
 He did his most significant work from 1959 to 1978 using a ground-based array of detectors at Volcano Ranch in New Mexico.
 He is best known for being the first to detect an air shower created by a primary particle with an energy of 10 eV.
 This was the highest energy cosmic ray observed up to that point.
 Linsley's observations suggested that not all cosmic rays are confined within the galaxy and showed the first evidence of a flattening of the cosmic ray spectrum at energies above 10 eV.
Spaceship Earth is a network of neutron monitors designed to measure the flux of cosmic rays arriving at Earth from different directions.
 All the 12 member neutron monitor stations are located at high (Northern or Southern) latitude, which makes their detecting directions more precise, and their energy responses uniform.
 Their combined signals provide a real-time measurement of the three-dimensional distribution of cosmic rays, mainly galactic cosmic rays as well as solar energetic particles during the most intense solar events.
 Analyses of these data have applications in space weather studies.
The Tunka experiment now named TAIGA (Tunka Advanced Instrument for cosmic ray physics and Gamma Astronomy) measures air showers, which are initiated by charged cosmic rays or high energy gamma rays. TAIGA is situated in Siberia in the Tunka valley close to lake Baikal.
 Meanwhile, TAIGA consists of five different detector systems: Tunka-133, Tunka-Rex, and Tunka-Grande for charged cosmic rays; Tunka-HiSCORE and Tunka-IACT for gamma astronomy.
 From the measurements of each detector it is possible to reconstruct the arrival direction, energy and type of the cosmic rays, where the accuracy is enhanced by the combination of different detector systems.
Cosmic ray spallation is a form of naturally occurring nuclear fission and nucleosynthesis.
 It refers to the formation of chemical elements from the impact of cosmic rays on an object.
 Cosmic rays are highly energetic charged particles from outside of Earth ranging from protons, alpha particles, and nuclei of many heavier elements.
 About 1% of cosmic rays also consist of free electrons.
A neutron monitor is a ground-based detector designed to measure the number of high-energy charged particles striking the Earth's atmosphere from outer space.
 For historical reasons the incoming particles are called "cosmic rays", but in fact they are particles, predominantly protons and Helium nuclei.
 Most of the time, a neutron monitor records galactic cosmic rays and their variation with the 11-year sunspot cycle and 22-year magnetic cycle.
 Occasionally the Sun emits cosmic rays of sufficient energy and intensity to raise radiation levels on Earth's surface to the degree that they are readily detected by neutron monitors.
 They are termed "ground level enhancements" (GLE).
