WFIRST, the Wide Field Infrared Survey Telescope, is shown here in an artist's rendering. It will carry a Wide Field Instrument to provide astronomers with Hubble-quality images covering large swaths of the sky, and enabling several studies of cosmic evolution. Its Coronagraph Instrument will directly image exoplanets similar to those in our own solar system and make detailed measurements of the chemical makeup of their atmospheres. http://photojournal.jpl.nasa.gov/catalog/PIA20060
