This is an artist’s illustration of the Wide Field Infrared Survey Telescope (WFIRST) spacecraft against a starry background. WFIRST is a Hubble-sized telescope planned for launch in the mid-2020s. It will revolutionize astronomy by building on the science discoveries and technological leaps of the Hubble and James Webb space telescopes. Webb offers superior sensitivity over Hubble, and WFIRST will provide a panoramic field of view that is 100 times greater than Hubble's, leading to the first wide-field maps of the universe at space-based resolution.
