NASA’s Nancy Grace Roman Space Telescope has exceeded expectations after engineers made incredibly tiny adjustments to sharpen its view of the universe. By moving a mirror just one-sixteenth the width of a human hair, the team helped bring its powerful instruments into near-perfect alignment. Roman’s Wide Field Instrument now produces image quality nearly 30% better than predicted, promising exceptionally sharp cosmic surveys.
