NASA's Nancy Grace Roman Space Telescope will survey vast swaths of sky during its five-year primary mission. During that time, scientists expect it to see an incredible number of new objects, including stars, galaxies, black holes and planets outside our solar system, known as exoplanets. This infographic previews some of the discoveries scientists anticipate from Roman's data deluge.
