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.
Galactic cosmic rays are one of the most important barriers standing in the way of plans for interplanetary travel by crewed spacecraft. Cosmic rays also pose a threat to electronics placed aboard outgoing probes. In 2010, a malfunction aboard the Voyager 2 space probe was credited to a single flipped bit, probably caused by a cosmic ray ...
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.
Stone tools unearthed in Ukraine were last used 1.4 million years ago, according to research that dated the tools using particles inside rock made by cosmic rays.
IceTop is used as a cosmic ray shower detector, for cosmic ray composition studies and coincident event tests: if a muon is observed going through IceTop, it cannot be from a neutrino interacting in the ice. The Deep Core Low-Energy Extension is a densely instrumented region of the IceCube array which extends the observable energies below 100 ...
The energy spectrum for cosmic rays. Extragalactic cosmic rays are very-high-energy particles that flow into the Solar System from beyond the Milky Way galaxy. While at low energies, the majority of cosmic rays originate within the Galaxy (such as from supernova remnants), at high energies the cosmic ray spectrum is dominated by these extragalactic cosmic rays.
The flux of cosmic rays is approximately proportional to 1/(E a) where E is the energy and a is somewhere between 2 and 3 up to the UHECR limit. Cosmic rays created in our galaxy with energy of less than about 10 18 eV get trapped by the galaxy's magnetic field. Particles above that should escape, so high energy cosmic rays would likely come ...
Hypotheses include Cherenkov radiation created as the cosmic ray particles pass through the vitreous humour of the astronauts' eyes, [4] [5] direct interaction with the optic nerve, [4] direct interaction with visual centres in the brain, [6] retinal receptor stimulation, [7] and a more general interaction of the retina with radiation.
