Core Insights - The "Milky Way Painting" (MWISP) survey plan officially released its first batch of millimeter-wave molecular line observation data, showcasing the contributions of Chinese astronomers to global astronomy [1][6] Group 1: Project Overview - The MWISP project, organized by the Purple Mountain Observatory, is a large-scale millimeter-wave molecular line survey that utilizes a 13.7-meter diameter millimeter-wave radio telescope located in Delingha, Qinghai [5][10] - The survey covers approximately 2300 square degrees near the northern galactic plane, specifically in the range of galactic longitude 10 to 230 degrees and latitude ±5 degrees [3][8] Group 2: Data and Findings - The released data includes over 100 million spectral lines, providing a comprehensive millimeter-wave CO molecular line database that offers an unprecedented panoramic view of the distribution and structure of molecular gas in the Milky Way [3][8] - The data reveals both the macroscopic distribution of molecular gas in the Milky Way and the internal details and physical properties of interstellar molecular clouds, aiding in the study of gas circulation and star formation processes [5][10] Group 3: Future Implications - The publicly available data is expected to promote collaborative innovation in multi-band astronomical research, complementing other major scientific facilities like the 500-meter Aperture Spherical Telescope (FAST) and the High Altitude Cosmic Ray Observatory (LHAASO) [5][10] - The MWISP project also accumulates important technical experience for next-generation large aperture millimeter/submillimeter telescopes with hundreds of beams for future surveys [11]
