9315300 Janes Although some stars in our galaxy may have formed soon after the origin of the universe, the galaxy itself probably coalesced only gradually with the galactic disk forming several billion years later. Old open star clusters which formed early in the history of the disk will be studied. An improved understanding of the relation between the ages, compositions and velocities of these objects will be sought. This information is essential to constructing a comprehensive model for the formation and evolution of the galactic disk. ***

9315300 Janes虽然我们银河系中的一些恒星可能在宇宙起源后不久就形成了，但银河系本身可能只是在几十亿年后才逐渐合并成银河系盘。将研究在盘的历史早期形成的古老的疏散星星星团。将寻求对这些物体的年龄、成分和速度之间关系的更好理解。这些信息对于构建星系盘形成和演化的综合模型至关重要。***
