A survey of the Milky Way building blocks with the Hubble Space Telescope.

最近的研究导致了恒星群研究中最令人兴奋和意想不到的发展之一：在球状星团中发现了多代恒星。这些发现极大地改变了人们对这些看似简单的恒星系统的传统看法，并提供了球状星团是银河系晕的组成部分的证据。哈勃太空望远镜正在收集大量数据，作为对球状星团中多代人的首次调查的一部分。该项目基于这一独特的数据集，旨在为了解球状星团的起源和演化以及构建银河系的形成机制提供重大进展。

Recent studies have resulted in one of the most exciting and unexpected developments in stellar-population studies: the discovery of multiple stellar generations in globular clusters. These findings have dramatically changed the traditional picture of these seemingly simple stellar systems and provided evidence that the globulars are building blocks of the Galactic halo. The Hubble Space Telescope is in the process of collecting a large amount of data as part of the first survey of multiple generations in globular clusters. The project is based on this unique dataset and aims to provide a major advance to understand the origin and the evolution of globular clusters, as well as the formation mechanisms that build the Milky Way.
