Among scientists there is no consensus on their origin .
Eta Carinae, the largest and the agitated star galaxy, is constantly generating a huge amount of cosmic rays, accelerating the particles of matter at speeds close to light, according to an article published in the journal Nature Astronomy
"We have known for a long time that the shock waves generated after a supernova explosion, can accelerate the particles of matter at the speed of light and" charge "them with a large amount of energy "It turns out that similar processes can take place in other extreme environments, for example in the vicinity of stars like those of the keel," – said Kenji Hamaguchi (Hamaguchi Kenji) of the Space Flight Center from NASA Goddard to Greenbelt (U SA
Cosmic rays – elementary particles and atomic nuclei of different elements, accelerated at speeds close to light, have since long one of the main mysteries of science and sources of danger to the health of cosmonauts and astronauts. Today, among researchers, there is no consensus on their origin – some astronomers believe that these particles are accelerated in the hot remains of the exploded stars in the Milky Way, while d & # 39; others assume that they are the source of the nucleus and gas clouds. distant galaxies.
What is even more interesting, a third group of researchers think that they are generated by the disintegration of dark matter particles in the center of the galaxy.
Hamaguchi and his colleagues discovered another source of cosmic rays, observing the largest potentially the most dangerous star of the Milky Way – This supergiant in the constellation Carina, with a NuSTAR X-ray telescope.
