Date name/org/meeting 报告内容 虚拟天文台历史与现状 国际虚拟天文台联盟（IVOA） 中国虚拟天文台（China-VO） 虚拟天文台ABC VO concept 虚拟天文台是一个通过先进的信息技术把世界范围内的研究资源无缝透明联结起来组成的数据密集型网络化天文研究和科普教育环境，是e-Science时代天文学研究信息化的重要特征。 The power of the World Wide Web is its transparency. It is as if all the documents in the world are inside your PC. The idea of the Virtual Observatory is to achieve the same transparency for astronomical data and other related information (Quinn et al. 2004). VO历史回顾 1990s:NASA成立了按波长划分的科学数据中心，多个地基数字巡天项目开始 1999年4月, 美国理论、计算和数据发现十年规划调研专家组成立 Szalay, Prince, Alcock 提出 “National Virtual Observatory”的概念 1999年11月, NVO 在JHU组织研讨会 2000年2月, 第二届 NVO 研讨会在NOAO召开 2000年6月, “Virtual Observatories of the Future”在Caltech召开，褚耀泉参加会议 2001年2月, “新千年的天文学与天体物理学”发表 2001年9月, 美国NSF 宣布对NVO项目的资助 2002年6月，国际虚拟天文台联盟成立 International VO Alliance International VO Alliance International VO Alliance IVOA Events Second Science Paper from VO Accepted by AA Luminous AGB stars in nearby galaxies: A study using Virtual Observatory tools Searching for very luminous AGB stars with J ? Ks 1.5 mag and H ? Ks 0.4 mag in the LMC, SMC, M31, and M33 from 2MASS data. Next Steps: 2005-2010 AstroGrid at the thresh hold of enabling significant science Prioritisation on automating bulk workflows and data access Working in partnership to link to additional functionality Key science programmes for AstroGrid to 2007 and AstroGrid in the Euro-VO being formulated Focus on supporting major new (2007) data flows e.g. VISTA, Planck, Herschel, VLT Science is a major driver in AG2 and VOTECH (Euro-VO) GOAL: 2010 for 90% of all science to be VO enabled IVO Highlights (I) AstroGrid V2006.3 The first public release of VO infrastructure MySpace, Workflow, Query Builder, Job Monitor, Resource querying TopCat and Aladin Science Services: Solar Movie Maker, and Redshift Maker Science Services - Color Cutter, and AstroScope / IVO Highlights (II) Aladin v3.7 multiview: an interactive software sky atlas developed by CDS MultiView, multiProjection Resampling
