摘要：

哈勃太空望远镜（HST）已被证明是唯一适合于测量附近宇宙中恒星和星系的自行（PM）。在这里，我们总结了HSTPROMO合作的主要成果和正在进行的研究，在过去的十年中，已经执行了大约二十多个关于这个主题的观测和理论HST项目。这将继续彻底改变我们对许多天体的动力学理解，包括：球状星团;年轻星团;银河系晕中的恒星和恒星流;本星系群星系，包括矮卫星星系，麦哲伦云和仙女座星系;以及AGN黑洞喷流。

英文摘要：

The Hubble Space Telescope (HST) has proven to be uniquely suited for the measurement of proper motions (PMs) of stars and galaxies in the nearby Universe. Here we summarize the main results and ongoing studies of the HSTPROMO collaboration, which over the past decade has executed some two dozen observational and theoretical HST projects on this topic. This is continuing to revolutionize our dynamical understanding of many objects, including: globular clusters; young star clusters; stars and stellar streams in the Milky Way halo; Local Group galaxies, including dwarf satellite galaxies, the Magellanic Clouds, and the Andromeda galaxy; and AGN Black Hole Jets.
