China's Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), a major piece of national scientific infrastructure which is operated by the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), has announced a series of technological breakthroughs and a new data-release milestone. According to the NAOC, as of October 2025, LAMOST has released a total of 28.07 million spectra and 11.59 million sets of stellar parameters, retaining its status as the world's leading producer of astronomical data.

A research team from the Yunnan Observatories of the Chinese Academy of Sciences has conducted a study on the binary fraction of Blue Horizontal-branch stars. Their findings provide the intrinsic binary fraction and reveal its relationship with metallicity, kinematics, and effective temperature.

Astronomers from China's National Astronomical Observatories, Peking University, University of Chinese Academy of Sciences, Beijing Normal University, and the Netherlands' Leiden University have found over 1,300 new quasars behind the Galactic plane by using China's Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), and the scientists said the results shed new light on some hot issues of cosmic research.

Researchers from the Chinese Academy of Sciences' National Astronomical Observatories (NAOC) in collaboration with multiple institutions have identified a runaway star that was ejected from the M15 globular cluster, providing strong evidence for the existence of intermediate-mass black holes (IMBHs), a long-missing link in our understanding of black hole evolution.
