The Roman Space Telescope is a NASA observatory designed to settle essential questions in the areas of dark energy, exoplanets, and infrared astrophysics.
More About Roman
The Roman Space Telescope will have a panoramic field of view of the universe that is 100 times wider than the Hubble Space Telescope.
Why Roman?
The Roman Space Telescope will delve into the mystery of dark energy by studying how the distribution of galaxies and dark matter has changed throughout cosmic history.

OCT 8, 2024 - A major component of NASA’s Nancy Grace Roman Space Telescope just took a spin on the centrifuge at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Called the Outer Barrel Assembly, this piece of the observatory is designed to keep the telescope at a stable temperature and shield it from stray light.
Each of the Core Community Surveys will provide data to many teams conducting a large number of diverse science investigations. Roman’s science objectives that will be addressed by the Core Community Surveys are Astrophysics with wide area near-IR surveys, Cosmology, and Exoplanet demographics.

The Coronagraph Community Participation Program (CPP) is planning and execute Coronagraph Instrument technology demonstration observations. The CPP is composed of multiple, competitively selected small, US-based teams, members of the Roman Project Team, and international partner teams from ESA, JAXA, CNES, and the Max Planck Institute for Astronomy. The primary goals of the CPP are to prepare simulation tools, target databases, and data reduction software for the execution of the Coronagraph Instrument technology demonstration.
