China’s Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) has released its latest dataset, DR13, containing over 30 million spectra—making it the world’s largest spectroscopic survey dataset. The data spans observations from 2011 to 2025 and includes both low- and medium-resolution spectra, along with a massive stellar parameter catalog.
LAMOST’s data continues to lead globally in both scale and output. More than 1,900 researchers from 278 institutions worldwide have used its data, producing over 2,200 scientific papers, with a significant share contributed by international astronomers.
As a major national astronomy project, LAMOST has enabled detailed studies of the Milky Way’s structure and evolution and contributed to discoveries in areas like stellar physics, exoplanets, and quasars, placing it among the world’s leading large telescopes.
