Galactic Disk

NGC891: Perkins

The age and properties of the galactic disk can be determined more precisely through accurate color-magnitude diagrams of open clusters and velocity measurements of disk stars. PRISM's large field of view will allow observations of entire clusters and its multi-object spectroscopy mode will allow simultaneous observation of the radial velocities of many outer disk stars.
