In 1995, [15] [circular reference] the latter reported the detection of an ultrahigh-energy cosmic ray with an energy beyond the theoretically expected spectral cutoff. [16] The air shower of the cosmic ray was detected by the Fly's Eye fluorescence detector system and was estimated to contain approximately 240 billion particles at its maximum.
The Akeno Giant Air Shower Array (AGASA) [1] was an array of particle detectors designed to study the origin of ultra-high-energy cosmic rays. It was deployed from 1987 to 1991 and decommissioned in 2004. It consisted of 111 scintillation detectors and 27 muon detectors spread over an area of 100 km 2.
Penrose Colorado, Dec. 05, 2024 (GLOBE NEWSWIRE) -- Estes Rockets, a pioneer in rocketry and STEM education, is thrilled to announce the launch of Cosmic Club, a groundbreaking program designed to bring the excitement of space exploration and hands-on STEM learning directly to classrooms, camps, youth groups, and clubs across Colorado.
Thomas Korff Gaisser (March 12, 1940, Evansville, Indiana – February 20, 2022, Swarthmore, Pennsylvania) [1] was a particle physicist, cosmic ray researcher, and a pioneer of astroparticle physics. [2] He is known for his book Cosmic Rays and Particle Physics [3] and the Gaisser–Hillas function. [4]
Cosmic rays are charged particles that travel through space and rain down on Earth constantly. Low-energy cosmic rays can emanate from the sun, but extremely high-energy ones are exceptional. They ...
Cosmic ray astronomy faces difficulty in identifying the exact sources of cosmic rays because charged particles are deflected by magnetic fields in space, and as a result tracing the paths of cosmic rays back to their origins require sophisticated modeling techniques and multi-messenger observations to infer their source locations.
The new cosmic ray was detected by the Telescope Array experiment, which brings together 507 different stations in a grid of in the Utah desert to detect cosmic rays and other phenomena. It has ...
The Oh-My-God particle was an ultra-high-energy cosmic ray detected on 15 October 1991 by the Fly's Eye camera in Dugway Proving Ground, Utah, United States. [1] [2] [3] As of 2025, it is the highest-energy cosmic ray ever observed. [4] Its energy was estimated as (3.2 ± 0.9) × 10 20 eV (320 exa-eV). The particle's energy was unexpected and ...
