Gaia@AIP

Launched in December 2013, Gaia is destined to create the most accurate map yet of the Milky Way. By making accurate measurements of the positions and motions of stars in the Milky Way, it will answer questions about the origin and evolution of our home galaxy. The first data release (2016) contains three-dimensional positions and two-dimensional motions of a subset of two million stars. The second data release (2018) increases that number to over 1.6 Billion. Gaia’s measurements are as precise as planned, paving the way to a better understanding of our galaxy and its neighborhood. The AIP hosts the Gaia data as one of the external data centers along with the main Gaia archive maintained by ESAC and provides access to the Gaia data releases as part of Gaia Data Processing and Analysis Consortium (DPAC).

于2013年12月启动的盖亚项目，旨在绘制迄今为止最为精确的银河系星图。通过精确测量银河系内恒星的位置与运动，盖亚将解答关于我们家园星系的起源与演化的诸多疑问。首个数据发布（2016年）包含了约两百万颗恒星的三个维度位置和二维运动信息。第二个数据发布（2018年）将这一数字提升至超过16亿颗。盖亚的测量精度达到了既定标准，为深入理解银河系及其邻近区域铺就了道路。欧洲空间局科学和技术中心（ESAC）维护的主要盖亚档案库之外，AIP还作为外部数据中心之一托管盖亚数据，并作为盖亚数据处理与分析联合体（DPAC）的一部分，提供对盖亚数据发布的访问。
