Exploring ancient star clusters together, China's Five-hundred-meter Aperture Spherical Radio Telescope collaborates with South Africa's array telescopes to push the limits of observation.

Recently, Tsinghua University collaborated with astronomers from Italy, Australia, Germany and other countries to conduct high-precision observations of the globular clusters in the Milky Way using the Chinese FAST and South African MeerKAT array telescopes. This provided the most comprehensive measurements of the magnetic field gradient and upper limit of ionized gas in globular clusters to date, producing a clearer map of the Milky Way's magnetic field and offering new insights into the evolution of star clusters and the Milky Way's magnetic field. It is understood that in the future, the Chinese FAST and South African MeerKAT array telescopes will continue to collaborate in tracking pulsar bursts, studying interstellar turbulence, and even exploring possible signals from extraterrestrial civilizations.
