Exploration of transient sources represents one of the last frontiers in modern astrophysics. The development of a comprehensive understanding of a new event requires real-time observation with multiple instruments. Yet while telescope facilities continue to ramp up to unprecedented data rates, there has been no concerted effort to ensure real-time communications of astronomical events. A federated response must be enabled to push transient astrophysics ahead in the 21st century.The activity undertaken in this project is a synergy of distributed computing with distributed sensors. Though set up by humans with pre-defined criteria, VOEventNet operates automatically and autonomously. The project will build an event factory to detect sky transients in near real time, and utilize novel machine-learning technology to distinguish scientifically relevant transients from false positives through synthesizing multiple observations. In this way, VOEventNet will enable an already active area of astrophysical research to flourish. The system that will be enable constitutes the unification of existing powerful resources to form a new, robust, competent production system that will generate a great deal of new science.

对瞬变源的探索是现代天体物理学最后的前沿领域之一。要全面了解一个新事件，就需要使用多种仪器进行实时观测。然而，虽然望远镜设备继续提高到前所未有的数据速率，但还没有协调一致的努力来确保天文事件的实时通信。为了在21世纪推动瞬态天体物理学的发展，必须采取联合应对措施。在这个项目中进行的活动是分布式计算与分布式传感器的协同作用。虽然VOEventNet是由人类按照预先定义的标准设置的，但它是自动和自主运行的。该项目将建立一个事件工厂，以近实时地检测天空瞬变，并利用新颖的机器学习技术，通过综合多个观测结果，将科学相关的瞬变与误报区分开来。通过这种方式，VOEventNet将使一个已经活跃的天体物理学研究领域蓬勃发展。能够实现的系统是将现有的强大资源统一起来，形成一个新的、健全的、有能力的生产系统，从而产生大量的新科学。
