| 摘 要： | 在过去的几十年间,天文科学数据量已经从GB量级进入到了TB量级。如今,正在从TB量级向PB量级迈进。天文学研究已经进入到了数据密集型时代。面对海量天文数据对存储、计算、带宽、软件甚至工作模式等方面的需求,天文学家连同信息技术领域、计算机科学领域的专家正努力使基于天文数据的知识发现过程变得更加容易。旨在实现科学数据互操作的虚拟天文台就是这方面的积极尝试,它将为数据密集型时代的天文学研究和教育科普提供一个信息化环境。天文信息学则从天文学一个分支学科的高度去考虑天文学的长远发展。文章论述了天文学研究在数据密集型时代所面临的需求,介绍了天文学家为应对数据密集型挑战正在研究开发的虚拟天文台技术,探讨天文信息学所包含的内容和发展天文信息学的必要性,展望了中科院统筹规划天文领域科研信息化工作,建设中国虚拟天文台的前景。

| Abstract: | During the last decades, Astronomy has been stepped into a data intensive era. TB datasets have been in hands, and PB datasets are emerging. Big data in astronomy brings challenges on data management, computing, bandwidth, software, and even the way to do research. Astronomers are working together with experts in computer science and information technology to provide an easy way to discover knowledge from big data. Virtual Observatory (VO) is a data-intensively online astronomical research and education environment, taking advantages of advanced information technologies to achieve seamless, global access to astronomical information. To allow users and applications to access distributed and heterogeneous datasets and services in a consistent and uniform way (interoperability), International Virtual Observatory Alliance (IVOA) has been defined a set of standards and specifications. However, the VO, especially the IVOA, does not address all of the challenges faced to astronomical research and education in a data-driven and data-intensive science research era. Standing on a broader vision, Astroinformatics will act as a sub-discipline of Astronomy to enable data-intensive astronomical science. In the paper, backgrounds and current status of VO research and development are introduced, challenges faced to Astronomy and requirements for Astroinformatics are discussed, activities and achievements from CAS astronomical observatories on e-Science are reviewed, prospects for VO in China is described. |
