In 2021, scientists picked up the new cosmic ray, named Amaterasu, when it triggered 23 of those detectors. The array showed that it was coming from the Local Void, an empty part of space on the ...
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.

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 2023, 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 ...
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.
Multiple telescopes observed a rare cosmic explosion called a kilonova that created heavy elements in space, including some necessary for life. Explosion 1 million times brighter than the Milky ...
A rare cosmic eruption is expected to occur in the Milky Way in the coming months — an outburst so bright that a “new” star will seemingly appear for a short time in the night sky.
Right image: cosmic ray muon losing considerable energy after passing through the plate as indicated by the increased curvature of the track in a magnetic field. Cosmic rays or astroparticles are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light.
A light-year is the distance light travels in one year, which is 5.88 trillion miles (9.46 trillion kilometers). But for the first time, a ring of light has been revealed around the galaxy while ...
