Roman Space Telescope widens its view to map the sky 1,000× faster
With the same 2.4-meter mirror as Hubble, Roman will not go deeper but cover far more sky per exposure with a 300-megapixel infrared camera, surveying more than 50× as much sky in five years as Hubble did in 30 and up to 1,000× faster overall. This breadth enables large-scale studies of dark energy, exoplanet microlensing, and time-domain astronomy, while a sophisticated data system turns massive image catalogs into usable science—complementing, not replacing, Hubble and Webb.
