BEIJING, Nov. 30 (Xinhua) -- China's Dark Matter Particle Explorer (DAMPE) has detected unexpected and mysterious signals in its measurement of high-energy cosmic rays, which might bring scientists a step closer to shedding light on invisible dark matter.


The satellite Reilly Smith Jersey , also called Wukong, or Monkey King, has measured more than 3.5 billion cosmic ray particles with the highest energy up to 100 tera-electron-volts (TeV for short, corresponding to 1 trillion times the energy of visible light), including 20 million electrons and positrons, with unprecedentedly high energy resolution.


""DAMPE has opened a new window for observing the high-energy universe, unveiling new physical phenomena beyond our current understanding,"" said Chang Jin Brendan Leipsic Jersey , chief scientist of DAMPE and vice director of the Purple Mountain Observatory of the Chinese Academy of Sciences (CAS).


The initial detection results were published in the latest issue of the academic journal, Nature.


""This is the first time a space experiment has reported a detailed and precise electron and positron spectrum up to about 5 TeV. In this energy range, we found some unexpected and interesting features. We have detected a spectral break at 0.9 TeV and a possible spike at 1.4 TeV,"" said Chang.


Precise measurement of cosmic rays, especially at the very high energy range, is important for scientists to look for traces of dark matter annihilation or decay, as well as to understand the most energetic astrophysical phenomena in the universe, such as pulsars Colin Miller Jersey , active galaxy nuclei and supernova explosions. ""Our data may inspire some new ideas in particle physics and astrophysics,"" said Chang.

Dark matter Deryk Engelland Jersey , which cannot be seen or touched, is one of the great mysteries of science. Scientists calculate that normal matter, such as galaxies, stars, trees, rocks and atoms, accounts for only about 5 percent of the universe. However, about 26.8 percent of the universe is dark matter and 68.3 percent dark energy.
