3. China-VO 2005 VO concept 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. 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).

4. China-VO 2005 VO concept (cont.) The VO is: A set of international standards to share complex data A modular set of tools to work with distributed data A simple environment to publish data to An essential part of the research astronomer’s toolkit A catalyst for world-wide access to astronomical archives A vehicle for education and public outreach The VO is not: A replacement for building new telescopes A centralized repository for data A data quality enforcement organization

5. Nov. 25-27China-VO 20055 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

13. Nov. 25-27China-VO 200513 First Science Paper from VO A&A 424, 545-559 (2004) Discovery of optically faint obscured quasars with Virtual Observatory tools The AVO science team discovered 31 previously undetected powerful supermassive black holes in the so- called GOODS (Great Observatories Origins Deep Survey) fields.

14. Nov. 25-27China-VO 200514 Second Science Paper from VO Accepted by A&A 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.

15. Nov. 25-27China-VO 200515 The Next Steps: Participant in VO Science Demos 2005 AstroGrid: Consortium meeting: Today. 14 Dec 2004 — Galaxy distances — Brown dwarf discovery — Solar coronal mass ejections Euro-VO: ESAC, Madrid: 25-26 Jan 2005 — Star formation histories — AGB to PN transitions A Widening range of capabilities, data, applications — Increasing scientific usefulness GOAL: end 2005 – science papers enabled by VO

16. Nov. 25-27China-VO 200516 Next Steps: 2005-2007 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

17. China-VO 2005 IVO Highlights (I) AstroGrid V1.0 (2005.5) 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 AstroGrid V1.1 (Sep, 2005) Science Services - Color Cutter, and AstroScope more robust and reliable better documentation http://www.astrogrid.org/release/
