Completing the Nancy Grace Roman Telescope's Primary Mirror

The Nancy Grace Roman Space Telescope's primary mirror, which will collect and focus light from cosmic objects near and far, has been completed. Using this mirror, Roman will capture stunning space vistas with a field of view 100 times greater than Hubble images. Roman will peer through dust and across vast stretches of space and time to study the universe using infrared light, which human eyes can't see. The amount of detail these observations will reveal is directly related to the size of the telescope's mirror since a larger surface gathers more light and measures finer features.
