Exploring Dark Energy, Exoplanets, and Infrared Astrophysics at 100x the scale of Hubble

Delving into the mysteries of dark energy

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.

Discovering thousands of exoplanets

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.

Leading future exoplanet missions

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.

The Roman Mission requests the astronomical community's input on the definition of the Core Community Surveys here.

NASA’s Roman Mission Gets Cosmic ‘Sneak Peek’ From Supercomputers

Scientists at NASA’s Jet Propulsion Laboratory contributed to a project that sets the stage for two telescopes investigating one of astrophysics’ biggest mysteries.

The Roman Space Telescope and IPAC

Caltech/IPAC hosts the Roman Science Support Center (SSC). The responsibilities of the SSC include Coronagraph Instrument operations, science level processing of spectroscopic and microlensing WFI data, General Astrophysics proposal and grants management, and community engagement. The SSC also curates up to date telescope and instrument parameters and Roman science simulations and tools for the scientific community.
