China's 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. "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 Jin, Chief Scientist of DAMPE and Vice Director of the Nanjing Purple Mountain Observatory of the Chinese Academy of Sciences (CAS). More data will be needed to confirm what DAMPE is possibly seeing.
