WFIRST Gets its Coronagraph, to Block the Light of Stars and Reveal Their Planets

NASA's Wide Field Infrared Survey Telescope (WFIRST) will capture Hubble-quality images covering swaths of sky 100 times larger than Hubble does, enabling cosmic evolution studies. Its Coronagraph Instrument will directly image exoplanets and study their atmospheres. Credits: NASA/GSFC/Conceptual Image Lab

In the next decade, NASA will be sending some truly impressive facilities to space. These include the next-generation space telescopes like the James Webb Space Telescope (JWST) and the Wide-Field Infrared Space Telescope (WFIRST). Building on the foundation established by Hubble, WFIRST will use its advanced suite of instruments to investigate some of the deepest mysteries of the Universe.

One of these instruments is the coronagraph that will allow the telescope to get a clear look at extra-solar planets. This instrument recently completed a preliminary design review conducted by NASA, a major milestone in its development. This means that the instrument has met all design, schedule and budget requirements, and can now proceed to the next phase in development.
