The world’s first solar magnetic-field telescope operating in the mid-infrared wavelength range has officially become operational after gaining government approval, marking a major breakthrough in solar magnetic field research.
The telescope, known as the Accurate Infrared Magnetic Field Measurements of the Sun, or AIMS, is located in Lenghu township, Qinghai province, at an average altitude of about 4,000 meters. AIMS’ development addresses a long-standing bottleneck in the century-old history of solar magnetic field measurements by achieving a leap from indirect to direct measurement, scientists said.
“The sun, being the only star we can observe with high precision, has a magnetic field that acts as the energy switch driving intense solar activities such as flares and coronal mass ejections. Yet, more than half the sun’s overall magnetic field manifestations are relatively weak, with strengths of only a few dozen gauss,” said Deng Yuanyong, a researcher at the National Astronomical Observatories of the Chinese Academy of Sciences, who led the telescope’s construction.
