Introducing
the
Nancy Grace Roman
Space Telescope

Slide Background

The Roman Space Telescope is a NASA observatory designed to settle essential questions in the areas of dark energy, exoplanets, and infrared astrophysics.

Slide background

The Roman Space Telescope will have a panoramic field of view of the universe that is 100 times wider than the Hubble Space Telescope.

Slide background

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.

Slide background

The Roman Space Telescope will complete the statistical census of planetary systems in the galaxy by using microlensing, the universe’s own magnifying glass, to find thousands of exoplanets.

Slide background

The Roman Space Telescope will use a technique called coronagraphy to block the glaring light of exoplanet host stars to directly see planets and planet-forming disks. The Coronagraph Instrument is an advanced technology demonstrator for future exoplanet missions.

NASA’s Roman Mission Will Help Empower a New Era of Cosmological Discovery

Nov 9, 2021 - A team of scientists has forecast the scientific impact of the Nancy Grace Roman Space Telescope’s High Latitude Wide Area Survey on critical questions in cosmology. This observation program will consist of both imaging, which reveals the locations, shapes, sizes, and colors of objects like distant galaxies, and spectroscopy, which involves measuring the intensity of light from those objects at different wavelengths, across the same enormous swath of the universe.

About the Mission

The Roman Space Telescope is a NASA observatory designed to unravel the secrets of dark energy and dark matter, search for and image exoplanets, and explore many topics in infrared astrophysics.

  • The Roman Space Telescope has a 2.4m telescope, the same size as Hubble’s, but with a view 100 times greater than Hubble’s.
  • The Roman Space Telescope was the top-ranked large space mission in the 2010 Decadal Survey of Astronomy and Astrophysics.
  • The Roman Space Telescope is slated to launch in the mid-2020s.
  • The Roman Space Telescope will have no proprietary data period and all observing time will be competed.
