Artist concept of Roman's array of 18 detectors, outlined in light blue against a navy blue background with stars. They are arranged in an arc, with six columns of boxes across and three rows down. A thin, white, arched line in the lower left of the graphic is labeled "Moon's apparent size." Blue text over the left-most column of detectors reads, "WFI 2700 x 1360 arcseconds. Two yellow boxes on the far left are labeled "NIRCam 260 x 130 arcseconds." And a white box on the left, below the yellow boxes, is labeled "WFC3 NIR 130 x 130 arcseconds."
