How the Roman Sky Atlas works
Each glowing marker is an image that NASA published with sky coordinates, pinned to its real right ascension and declination and drawn at its true angular size when the field of view is known. Zoom in far enough and the picture appears in place. As Roman’s survey images arrive they appear here automatically.
The shaded ring shows where Roman is allowed to point today: between 54° and 126° from the Sun, about 59 percent of the sky. It sweeps around the sky over the year as Earth orbits the Sun. Turn on Roman’s eye to see the true size and shape of one Wide Field Instrument exposure — and Hubble’s and Webb’s cameras beside it — anywhere you look.
