Chinese observatories operating in space and on the ground are being used together to trace the long journey of cosmic rays, Macau Business reports.
The work, reported on Monday, September 21, 2026, involves tracking these high-energy particles across their travel paths using instruments based both above the atmosphere and on the Earth's surface. Macau Business did not publish further details of the findings or the specific facilities involved.
Cosmic rays are studied through a combination of detection methods because the particles interact with the atmosphere before reaching the ground. Pairing space-based instruments with ground-based observatories allows researchers to gather data at different points along a cosmic ray's route, according to Macau Business.
The report frames the effort as part of China's broader use of multiple observation platforms to study cosmic rays. Macau Business did not specify which missions or observatory sites contributed to the work, nor did it give figures on the number of events detected or the energy ranges examined.
Further results from the joint observation effort have yet to be detailed. Watch for additional reporting from Macau Business or the participating observatories for specifics on the data collected and what it shows about how cosmic rays travel.
