Core Insights - China has discovered 1,152 pulsars, showcasing a significant advancement in astronomical research, particularly with the Five-hundred-meter Aperture Spherical Telescope (FAST) [1] - The search for extraterrestrial civilizations is one of the primary missions of the FAST telescope, indicating a dual focus on both pulsar research and the quest for alien life [1] Group 1 - The discovery of 1,152 pulsars positions China as a leader in this field of study, highlighting the capabilities of the FAST telescope [1] - Pulsars are highly magnetized rotating neutron stars that emit beams of electromagnetic radiation, which can be detected from Earth, providing valuable data for astrophysics [1] - The advancements in pulsar research may lead to new insights into fundamental physics and the nature of the universe [1]

Group 1 - The collaboration between Tsinghua University and international astronomers has successfully created a clearer magnetic field map of the Milky Way by utilizing the FAST and MeerKAT telescopes, providing new insights into star cluster evolution and the Milky Way's magnetic field [1][3] - Globular clusters, among the oldest celestial bodies in the Milky Way, consist of millions of stars, including highly magnetized pulsars that emit precise electromagnetic signals, carrying valuable information about interstellar matter and magnetic fields [3][6] - The joint observation effort has resulted in the measurement of polarization rotation for 43 pulsars across 8 globular clusters, which is a key indicator of cosmic magnetic field strength, revealing that 7 of the clusters lack detectable ionized gas, indicating an unusually "clean" environment [6][7] Group 2 - The term "dust-free realm" has been coined to describe the exceptionally clean environment of these ancient celestial bodies, raising new questions about how globular clusters have maintained such cleanliness over billions of years [6][7] - Future collaborations will focus on tracking pulsar mutations, studying interstellar turbulence, and even exploring potential signals from extraterrestrial civilizations [7]
