□本报记者 李 遥 李建成 2月10日，农历腊月二十三，北方小年。 15时许，记者乘车沿着盘山路缓缓爬上承德市兴隆县境内的燕山主峰南麓。山巅之上的巨大白色建筑 里，藏着一双凝望星空的"眼睛"——郭守敬望远镜。这里是中国科学院国家天文台兴隆观测站。 （来源：河北日报） 转自：河北日报 跟着"郭守敬"追星星 七百多年前，元代天文学家、河北邢台人郭守敬编撰《授时历》，在全国设27个观测点。今天，以他名 字命名的这架望远镜，正将人类的目光推向银河深处。 小年当天晴空万里，是难得的观测窗口。观测19时开始，但从15时30分起，准备工作就已悄然启动。开 启电源，检查设备，检查光路，撤掉镜罩，打开穹顶……观测助手刘洋和同事们逐项严格检查，不落下 一个细节。 很多人问过刘洋："你们能拍到许多漂亮的星星吧？"他每次都摇头。郭守敬望远镜并不拍星空的照片。 它全称叫大天区面积多目标光纤光谱天文望远镜，是我国自主研制的国家重大科技基础设施，一次能盯 4000颗星。 19时，电脑语音下达启动指令，李卓按下第一次曝光键。一次曝光约20分钟，每个天区曝光3次，加上 前期准备，观测一个天区差不多两小时。冬季一晚上，能看五六个天区，为两万多颗 ...

Core Insights - The "Milky Way Imaging Survey Project" (MWISP) has officially released its first batch of millimeter-wave molecular line observation data to the global community, marking a significant milestone in astronomical research [1][6]. Group 1: Project Overview - The MWISP is a large-scale millimeter-wave molecular line survey covering 2,310 square degrees near the northern galactic plane, specifically from galactic longitude 10 to 230 degrees and latitude ±5.25 degrees [3][6]. - The project has been in development since 2011, culminating in over 100 million spectral line data points, creating the most comprehensive millimeter-wave carbon monoxide molecular line database to date [3][6]. Group 2: Technological Advancements - The survey utilizes a 13.7-meter diameter millimeter-wave radio telescope located at the Qinghai Observation Station, which is currently the only large-scale radio astronomical observation equipment in China operating in the millimeter-wave band [3][6]. - The core backend instrument, a multi-beam superconducting imaging spectrometer, enhances observational efficiency by 60 times compared to traditional methods, allowing for high-sensitivity and high-resolution surveys of molecular gas in the Milky Way [3][6]. Group 3: Scientific Contributions - The MWISP data exhibits significant advantages in sensitivity, dynamic range, multi-line simultaneous observation, and uniform sampling across large areas, surpassing previous international carbon monoxide survey projects [6]. - The data provides a detailed view of the macro distribution structure of molecular gas in the Milky Way and reveals internal details and physical properties of interstellar molecular clouds, supporting research on gas circulation and star formation processes [6]. Group 4: Future Implications - The release of this data is expected to promote collaborative innovation in multi-band astronomical research, aiding domestic and international research teams in studies related to star formation and galaxy evolution [6]. - The success of the MWISP lays the groundwork for future large-aperture millimeter/submillimeter telescopes to conduct surveys with hundreds of beams, highlighting China's growing capabilities in astronomical data support and international collaboration [6].
