hackingbear shares a report from Science Magazine: Results reported by a China-led space science mission provide a tantalizing hint -- but not firm evidence -- for dark matter. In its first 530 days of scientific observations, China's Dark Matter Particle Explorer (DAMPE) detected 1.5 million cosmic ray electrons and positrons above a certain energy threshold. When researchers plot of the number of particles against their energy, they saw hints of an anomalous break in the curve. Now, DAMPE has confirmed that deviation. "It may be evidence of dark matter," but the break in the curve "may be from some other cosmic ray source," says astrophysicist Chang Jin, who leads the collaboration at the Chinese Academy of Science's Purple Mountain Observatory in Nanjing. DAMPE's life span will be extended to 5 years given the excellent conditions of this Chinese spacecraft, then it can record over 10 billion cosmic events, allowing researchers to confirm if it is indeed dark matter.
