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]

Core Viewpoint - The "China Sky Eye" (FAST) has discovered a total of 1,152 pulsars, surpassing the total number of pulsars found by other international telescopes during the same period, significantly contributing to the understanding of pulsar formation and stellar evolution [1] Group 1: Pulsar Discoveries - FAST has identified a large number of pulsars, including many millisecond pulsars and pulsar binaries, enriching the variety and quantity of pulsars [1] - The total number of pulsars discovered by FAST exceeds that of all other international telescopes combined during the same timeframe [1] Group 2: Scientific Significance - Pulsars are rapidly rotating neutron stars that emit electromagnetic pulse signals, recognized as one of the densest celestial bodies, with extremely high density, strong magnetic fields, and intense gravity [1] - Observing pulsars provides critical data for testing theories such as general relativity and detecting low-frequency gravitational waves, serving as a natural laboratory for studying the four fundamental interactions and physical laws under extreme conditions [1] Group 3: Research Advancements - During the "14th Five-Year Plan" period, FAST not only discovered numerous pulsars but also achieved several original significant results, marking a transition for China's radio astronomy research from a follower to a leader in the field [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]

Group 1 - The research conducted by Tsinghua University and international astronomers utilized the FAST and MeerKAT telescopes to perform a high-precision pulsar polarization survey of globular clusters, providing the most comprehensive measurements of magnetic field gradients and ionized gas limits to date [1] - The study observed 43 pulsars across 8 globular clusters, doubling the global sample size and creating a clearer map of the Milky Way's magnetic field [1] - The findings were published as a cover article in the journal "Science Bulletin" on May 20 [1] Group 2 - The research revealed that, apart from 47 Tucanae, other globular clusters lacked detectable ionized gas, contradicting theoretical models that predicted significant gas presence [2] - This unexpected finding suggests the existence of effective gas-clearing mechanisms within globular clusters, potentially driven by strong radiation winds from white dwarfs and young stars [2] - The results challenge existing theories of globular cluster evolution, prompting a reevaluation of current models [2]
