[November 22 AFP] It was observed at the observatory of the arctic cold which has the elementary particle “neutrino” of the high energy which came flying from the outside of the solar system in the South Pole, and the report of research that rare new information was acquired was published on the 21st at the U.S. science journal science (Science).
According to 1 of coauthors of ? paper, and U.S. University of Maryland (University of Maryland) Professor Calah Hoffmann (Kara Hoffman) (physics) Particles like this ghost exist everywhere and it is said that per second billions of neutrinos have also passed through our body.
According to [ although it is ? it is very new that the farthest limit of our galaxy or the neutrino of further a long distance is observed, and ] the specialists It is said that the cosmic ray of high energy with such mass near zero may have occurred according to the ultimate phenomenon of the universes, such as a supernova, a black hole, and a pulsar.
Since it observed for the first time in 1987, detection of the neutrino which came flying from ? space has been the 2nd time in history.
And it is said that the energy which the neutrino observed this time has is about 1 million times as high as the last thing.
He is a senior research scientist of the world’s largest neutrino observatory “ice cube (IceCube)” in the underground in ? South Pole, U.S. University of Wisconsin (University of Wisconsin) Professor Francis Halzen (Francis Halzen) (physics) “this, It said that they are the first signs that show that the neutrino of high energy is coming flying from the outside of the solar system very much”, and continued, saying “This is the dawn of an astronomical new era.”
Although the neutrino observed in ? 1987 was related to the supernova which occurred in Large Magellanic Cloud (Large Magellanic Cloud), it is unknown with what kind of phenomenon the neutrino detected this time occurred.
The thing that it turned out that 28 high-energy neutrinos were caught as a result of detection of ? this time investigating the data collected in May, 2012 after May, 2010 by the ice cube of the particle detector which 12 nations built in antarctic ice together.
? ice cube public-relations charge — Mr. Olga ボトナー (Olga Botner) of the Uppsala university (Uppsala University) of Sweden — “– we raise the meaning of this observation now — It is said that and this signal means what and is tackling eagerly to understand where it is coming from.”
