        "content": "<p>Beijing (ANTARA) - A team of Chinese researchers has successfully\ndeveloped an artificial intelligence (AI) model called SpecCLIP, which\nis capable of interpreting stellar spectral data from various\ntelescopes, demonstrating the great potential of AI in processing and\nintegrating massive astronomical datasets, as reported by Science and\nTechnology Daily on Wednesday (February 25).<\/p>\n<p>Stellar spectra contain unique information about stars, including\ntheir temperature, chemical composition, and surface gravity. By\nanalysing these spectra, astronomers can trace the evolutionary history\nof the Milky Way galaxy from its early formation to the present day.<\/p>\n<p>However, current research faces significant challenges: different\nsurvey projects, such as China\u2019s LAMOST and Europe\u2019s Gaia satellite,\nacquire spectral data using different methods, resolutions, and\nwavelength ranges. These datasets are like stories told in different\ndialects, making it difficult to combine them directly for large-scale\nanalysis.<\/p>\n<p>To overcome this data barrier, a team of researchers from the\nNational Astronomical Observatories under the Chinese Academy of\nSciences (CAS), the University of Chinese Academy of Sciences (UCAS),\nand other institutions introduced a concept similar to large language\nmodels into the field of astronomy and applied contrastive learning\nmethods, creating an AI that can independently learn and build intrinsic\nconnections between spectral data from different sources.<\/p>\n<p>According to Huang Yang of UCAS, SpecCLIP acts as a \u2018translator\u2019 that\ncan convert low-resolution spectra from LAMOST and high-precision\nspectra from Gaia into a \u2018universal language\u2019. With SpecCLIP, scientists\ncan easily perform combined analyses, as well as align and transform\ndata across various instruments and survey projects.<\/p>\n<p>According to the research, which has been published in the\nAstrophysical Journal, SpecCLIP is not a specialist AI model designed\nfor a single task, but rather a framework similar to a foundational\nmodel. This model can predict stellar atmospheric parameters and\nelemental abundances simultaneously, perform spectral similarity\nsearches, and even help identify unusual celestial objects.<\/p>\n<p>These capabilities are crucial in the field of galactic archaeology,\nas they promise the ability to efficiently sort through massive datasets\nto find rare and metal-poor ancient stars, which will provide important\nevidence for research on the early formation and merger history of the\nMilky Way galaxy.<\/p>\n<p>SpecCLIP has been applied in several cutting-edge exploration\nmissions. For example, in one mission to search for Earth-like planets,\nthe model was able to accurately characterise the features of\nplanet-hosting stars, thereby improving the efficiency of sorting\npotentially habitable planets.<\/p>",
