Core Insights - The LHAASO observatory in Sichuan, China, has made a significant discovery by systematically detecting five ultra-high-energy gamma-ray signals from microquasars formed by the interaction of black holes and companion stars, providing crucial evidence for the origin of cosmic rays [3] Group 1: Discovery Details - The detected gamma-ray signals are associated with particles that have energy levels in the "knee" region of the cosmic ray energy spectrum, which is characterized by a bend in the distribution of cosmic ray quantities at around 30 trillion electron volts [3] - The discovery indicates that microquasars act as powerful "particle accelerators," capable of accelerating cosmic rays to energies at or above the "knee" level, offering new observational evidence to solve the long-standing mystery of the formation of the cosmic ray "knee" [3] Group 2: Implications - This finding points to a new direction for research aimed at understanding the origins of cosmic rays, which have puzzled scientists for years, and suggests potential breakthroughs in the field of astrophysics [3]
