我们描述了欧洲、美国、日本和其他地方的虚拟观测站 (VO) 项目如何应对挑战，提供对来自世界观测设施的数据的简单有效的访问，以及支持这些数据分析所需的应用程序和计算资源。我们注意到泛欧 Euro-VO 项目及其技术开发 VO-TECH 项目，目前正在设计全面访问新兴高数据量设施（例如 ESO 的 VISTA 红外巡天望远镜）的框架。来自重大新天文任务的科学驱动力正在帮助确定 VO 的发展。从科学角度来说，这是指开发能够满足塑造 ELT 的主要科学项目需求的系统。 VO 必须能够处理来自 ELT 上复杂的多路复用仪器的大量数据流，并提供对分析/解释数据所需的应用程序的访问。 VO 必须能够向全球社区有效分发 ELT 数据。相反，虚拟天文台的快速发展为英语教学等重大新项目提供了机会。这可能是： 在其下游数据流系统的设计中；在开放辅助数据流的“实时”可用性方面；在多波长观测计划中。我们重点介绍这些领域，并给出一些当前早期 VO 在传播科学方面的具体示例，例如：挖掘深部多波长勘测来研究高红移宇宙。
We describe how the Virtual Observatory (VO) projects in Europe, the USA, Japan, and elsewhere are meeting the challenge of providing simple and efficient access to the data from the world's observational facilities, together with applications and computational resources required to support the analysis of this data. We note the pan-European Euro-VO project and its technological development VO-TECH project which are now in the process of designing the framework for comprehensive access to emerging high data volume facilities such as ESO's VISTA infrared survey telescope. Science drivers from major new astronomical missions are helping to define the development of the VO. Scientifically this is in terms of developing systems able to meet the demands of the main science programmes shaping the ELTs. VOs must be able to handle the large data streams from the complex multiplexed instruments on the ELTs, and provide access to applications required to analyse/interpret the data. VOs must enable the effective distribution of ELT data to the global community. Conversely, the rapid development of the Virtual Observatory, offers opportunities for major new projects such at the ELTs. This could be: in the design of their down stream data-flow systems; in terms of opening up access to ‘real-time’ availability of ancillary data flows; in multi-wavelength observational programmes. We highlight these areas, and give some specific current examples of early VO usage in delivering science from, e.g. the mining of deep multi-wavelength surveys to study the high redshift universe.
