Numerical simulations performed by the GRAPES - 3 collaboration on this event indicate that the Earth's magnetic shield temporarily cracked due to the occurrence of magnetic reconnection, allowing the lower energy
galactic cosmic ray particles to enter our atmosphere.

«Our analysis shows that the
galactic cosmic rays, which are charged
particles energetic enough to penetrate below the lunar surface, can dissociate the water, H2O, into H2 through various potential pathways.»
Since LRO's launch in 2009, the CRaTER instrument has been measuring energetic charged
particles —
particles that can travel at nearly the speed of light and may cause detrimental health effects — from
galactic cosmic rays and solar
particle events.
The space environment poses significant risks to both humans and satellites due to harmful radiation from
galactic cosmic rays and solar energetic
particles that can easily penetrate typical shielding and damage electronics.
UCI's Charles Limoli and colleagues found that exposure to highly energetic charged
particles — much like those found in the
galactic cosmic rays that will bombard astronauts during extended spaceflights — causes significant long - term brain damage in test rodents, resulting in cognitive impairments and dementia.
Some physicists think
galactic cosmic rays — high - energy
particles originating from faraway stars — might affect cloud formation.
Based on the previously measured concentrations of
galactic cosmic rays, many scientists suspect that the
particles get flung toward Earth in the shock waves of exploding stars.
Solar
particles are just one form of radiation astronauts will have to contend with on a deep - space mission, however, including X-
rays, gamma
rays, and — above all —
galactic cosmic rays.
If the mission succeeds, astronauts could spend several years potentially being bombarded with
cosmic rays — high - energy
particles launched across space by supernovae and other
galactic explosions.
High - energy
particles called
galactic cosmic rays could be an energy source for life on other planets.
The radiation might not come from radioactive materials on the planet itself, but rather from
galactic cosmic rays (GCRs)-- high - energy
particles that careen through the universe after being flung out of a supernova.
After accounting for the deflection of the
cosmic rays by the Milky Way's magnetic field, the team found that the
particles are travelling about 326 million light years from a region of extragalactic space containing several potential sources, such as active
galactic nuclei and starburst galaxies.
At the same time, the spacecraft also detected a corresponding uptick in
galactic cosmic rays, ultrafast
particles that come from outside the solar system.
CLOUD also finds that ions from
galactic cosmic rays strongly enhance the production rate of pure biogenic
particles — by a factor 10 - 100 compared with
particles without ions.
They arrived at that date because that's when Voyager recorded a permanent drop in heliosphere - produced
particles and an increase in
galactic cosmic rays from outside the solar system.
Martin Smith, We generally refer to the
particles from the Sun as «solar
particles,» or solar - event
particles, while the flux of extremely high - energy
particles from outsde the solar system are referred to as «
galactic cosmic rays» (GCR).
The magnetic field strength deflects more or less
galactic cosmic rays which are really very high energy charged
particles and the interaction between charge and magnetic field strength deflects them just like the magnets on the yoke of a cathode
ray tube deflects an electron beam.
It has been hypothesized that
galactic cosmic rays (GCR) create atmospheric ions which facilitates aerosol nucleation and new
particle formation with a further impact on the cloud formation (Kazil et al., 2012; Pierce and Adams, 2009).
