Slide Background

Roman Space Telescope

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 and by studying the observed brightness of Type Ia supernovae as a function of cosmic time.

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 Predicted to Find 100,000 Transiting Planets

Mar 31, 2021 - NASA's Nancy Grace Roman Space Telescope will create enormous cosmic panoramas, helping us answer questions about the evolution of our universe. Astronomers also expect the mission to find thousands of planets using two different techniques as it surveys a wide range of stars in the Milky Way.


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.
