Open clusters are not only tracers of the structure and evolution of the Milky Way but also ideal laboratories for studying star formation and stellar evolution. The massive data release from the Gaia mission has dramatically expanded the number of known open clusters; however, this has also introduced a tricky challenge: the thous...
12 19, 2025A recent international collaboration led by researchers from Yunnan University, the Shanghai Astronomical Observatory (Chinese Academy of Sciences), and the National Astronomical Observatory of Japan has unveiled new insights into the fragmentation mechanisms of high-mass star-forming regions. Using the Atacama Large Millimeter/sub...
12 16, 2025An international team of astronomers has published the first detailed study of C/2025 D1 (Groeller), a comet that will make the most distant closest approach to the Sun of any known comet. This icy wanderer, discovered earlier this year, is giving astronomers a unique window into the ancient materials that helped build our solar sy...
12 15, 2025Recently, an international team of astronomers developed a novel galaxy "dissection" technique that enables precise analysis of the distinct components within barred spiral galaxies. The findings, published in the academic journal 《Astronomy & Astrophysics》, open a new window into understanding the formation and evolution of gala...
12 15, 2025A joint research team from the Early Universe and High-Redshift Galaxy Group at the Shanghai Astronomical Observatory (SHAO), Chinese Academy of Sciences, and the Optical–Infrared Observational Research Group at Sun Yat-sen University (SYSU), has recently made significant progress in improving the quality of long-term light curves...
12 15, 2025Recently, an international team led by Shanghai Astronomical Observatory, Chinese Academy of Sciences (CAS), has developed a quantifiable, verifiable, and scalable standardized workflow for identifying Compact Symmetric Objects (CSOs), derived from milliarcsecond-level alignment between optical and radio positions by combining the ...
12 10, 2025Recently, a research team led by Prof. Peng Wang at the Shanghai Astronomical Observatory (SHAO), Chinese Academy of Sciences (CAS), achieved significant progress in the field of galaxy cluster angular momentum. Utilizing large-sample spectroscopic data from the Sloan Digital Sky Survey (SDSS), the team systematically revealed for ...
12 10, 2025Prof. Tao An from the Shanghai Astronomical Observatory (SHAO) proposed a novel "Precessing Magnetic Jet Engine" model to explain the peculiar Gamma-Ray Burst (GRB) 250702B, discovered on July 2, 2025. Over more than three hours, this GRB exhibited periodic flares approximately every 47 minutes. The new model not only elucidates th...
12 03, 2025A research team led by Dr. Lu Li and Prof. Zhengyi Shao from the Shanghai Astronomical Observatory (SHAO), Chinese Academy of Sciences, has released a new, homogeneous catalog of physical parameters for 1,232 open clusters derived from Gaia DR3 data.
11 28, 2025A latest cosmological simulation study has systematically revealed, for the first time, how the interaction between dark matter and dark energy significantly influences the rotation and shape alignment of dark matter halos in the universe. This research provides a new perspective for understanding the formation of large-scale cosmi...
11 25, 2025From October 27 to 29, 2025, the "CSST-MCI Early Science Workshop" was held at the Shanghai Astronomy Museum of the Shanghai Astronomical Observatory, CAS. The event was co-organized by the Shanghai Astronomical Observatory of the Chinese Academy of Sciences and the CSST (China Space-Station Survey Telescope) Yangtze River Delta Re...
10 29, 2025The Shanghai Astronomical Observatory PIFI Distinguished Team Project successfully held a series of international exchange activities in Shanghai from October 13 to October 25, 2025.
