• •Roman will be able to take images that capture a patch of the sky at least 100 times larger than Hubble can.
• •It has the ability to survey over 1,000 times faster than Hubble.
• •The telescope is specifically calibrated to capture images of the universe in visible and near-infrared light.
• •Roman has a coronagraph to help directly image exoplanets.

The Nancy Grace Roman Space Telescope, set to launch in September 2026, is designed to capture images of the cosmos at a scale previously unseen. Its wide field of view and rapid data processing capabilities will allow it to survey the sky at an unprecedented rate, potentially revealing new phenomena. Roman will focus on studying dark matter and dark energy, and it has the capability of directly imaging exoplanets. The telescope's primary mirror measures about 7.9 feet (2.4 meters) wide, which is similar to Hubble's.
