Exploring Cosmology, 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.

White Papers are currently being solicited by the Coronagraph Participation Program (CPP) for both technology and science observing ideas for the Coronagraph Instrument. Deadline is August 7!

The Roman Project welcomes suggestions for First Look Observations using the Wide Field Instrument (WFI). Deadline is August 11!

The ROTAC report on the Roman Core Community and General Astrophysics Surveys is available, including slides and video of a presentation of the report. More information can be found at the Roman Community Forum page.

Roman Coronagraph Instrument Call for White Papers

The Community Participation Program (CPP) is sponsoring a call for White Papers to collect concepts for technology demonstration and scientific exploration observations with the Coronagraph, with a due date of August 7th.

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.
