How Nancy Grace Space Telescope compares to the Hubble, James Webb

Key Points:

• NASA’s Nancy Grace Roman Space Telescope, launching on August 30 from Kennedy Space Center, will provide unprecedented wide-angle infrared views of the cosmos, capturing images 100 times larger than Hubble’s field of view with similar sharpness.
• Positioned near the Sun-Earth L2 Lagrange Point about 930,000 miles from Earth, Roman will operate in a stable, cold environment ideal for deep space observations, joining other missions like James Webb and ESA’s Euclid.
• Roman’s two main instruments include a 300-megapixel Wide Field Instrument for studying distant galaxies and cosmic expansion, and a powerful Coronagraph Instrument to directly image exoplanets by blocking starlight.
• Unlike Hubble’s zoom-like focus or James Webb’s deep infrared vision, Roman acts as a wide-angle panoramic camera, expected to observe light from over a billion galaxies and discover thousands of new exoplanets during its mission.
• Named after Dr. Nancy Grace Roman, NASA’s first chief astronomer and a pioneering figure in space-based astronomy, the telescope honors her legacy in advancing large space observatories and modern astronomy.
