NASA’s Nancy Grace Roman Telescope Leaves Earth to Chart the Stars

Astronomers will use data collected by Roman’s wide, deep gaze to study the dark universe and hunt for new worlds.

The top 3

  1. Largest Field of View Among Space Telescopes: Roman's Wide Field Instrument (WFI) has a field of view 100 to 200 times larger than Hubble's infrared view, enabling it to capture vast cosmic panoramas and survey the sky up to 1,000 times faster.
  2. Most Powerful Space Coronagraph Ever Launched: Roman carries the Coronagraph Instrument (CGI), an experimental tool at least 100 times more powerful than any existing facility, designed for direct imaging and spectroscopy of exoplanets by blocking starlight.
  3. Lightest Primary Mirror of its Size: Roman's 2.4-meter primary mirror, the same size as Hubble's, is more than four times lighter, weighing 410 pounds (186 kg) compared to Hubble's 1,825 pounds (828 kg), contributing to the spacecraft's agility.
