Roman and Hubble Scale Graphic with Andromeda Galaxy and Moon

This ground-based image of the Andromeda Galaxy highlights the large field of view of NASA's soon-to-launch Nancy Grace Roman Space Telescope, with Hubble's field of view and a full moon shown for comparison.

Alt text: An image of a spiral galaxy seen from a down-tilted view. It’s titled Andromeda Galaxy and nearly half of it is covered with a grid of squares, stacked in three arched rows of six squares each. The squares are labeled Roman field of view. At the upper left of them, a much smaller orange square is labeled Hubble field of view; it’s significantly smaller than even just a single Roman square. An image of the Moon is overlain on the bottom right, labeled Moon to scale. It’s about 70% of the size of the Roman squares.
