The researchers from the Technical University of Denmark said these cosmic rays could be the reason for several climatic anomalies across Earth's history.
HIGH energy cosmic rays whose origins have been a mystery for 50 years come from beyond our galaxy, the Milky Way, scientists have confirmed.
Cosmic rays are high-speed atomic nuclei with a wide range of energy -- the most powerful race at almost the speed of light.
Cosmic ray sensors can measure soil moisture at an unprecedented sub-kilometre scale.
In addition to shedding light on our cosmic neighborhood, the results offer an explanation for a decades-old mystery on why we measure more incoming high-energy cosmic rays on one side of the sun than on the other.
We expect the research groups using the computer system to announce many new observational results in the future that generate new insights into hitherto unknown phenomena relating to the universe and cosmic ray particles.
There have also been suggestions that when the Sun is particularly active, it blocks cosmic rays, thought to encourage the formation of clouds which then reflect the Sun's rays, leading to further temperature increases.
With the increase in solar activity, the primary cosmic ray intensity has decreased by 9 per cent during the past 150 years leading to lesser cloud cover and reduced albedo radiation being reflected back into space.
Besides of these phenomena of a local character, there are global reasons of cosmic ray intensity modulations determined by geophysical cyclic processes and processes related to solar activity.
For instance, at an altitude of one mile above sea level, the cosmic ray density is 3.
Scientists have discovered a previously unidentified nearby source of high-energy cosmic rays.
With increased solar activity (and stronger magnetic fields), the cosmic ray intensity decreases, and with it the amount of cloud coverage, resulting in a rise of temperatures on the Earth.
At a morning ceremony, students, physicists, teachers and Los Angeles Unified School District officials watched a crane lift a pair of 250-pound, funnel-shaped cosmic ray detectors onto the roof of the school's science building.
Lee Lewis piloted the Stratolab to a world altitude record of 76,000 feet on a flight to gather meteorological, cosmic ray and other scientific data necessary to improve safety at high altitudes.
Yoji Totsuka and Takaaki Kajita, both professor at the Institute for Cosmic Ray Research, affiliated with the University of Tokyo, and Masatoshi Koshiba, 75, professor emeritus at the university, became the first Japanese recipients of the award.
