China uses advanced solar telescopes to measure magnetic fields with unprecedented accuracy The Accurate Infrared Magnetic Field Measurements of the Sun (AIMS) are now operational in Lenghu Municipality, Qinghai Province, at an altitude of about 4,000 meters. This solar magnetic field telescope is the first in the world to operate in the mid-infrared wavelength range, marking a significant advance in the direct measurement of the Sun’s magnetic field. For decades, measurements relied on indirect methods, which limited accuracy. AIMS was developed to address these challenges, moving from traditional 100 gauss accuracy to measurements better than 10 gauss accuracy. Deng Yuanyong…
