NASA | WFIRST: Uncovering the Mysteries of the Universe

The Wide-Field Infrared Survey Telescope (WFIRST) is an upcoming space telescope designed to perform wide-field imaging and spectroscopy of the infrared sky. One of WFIRST’s objectives will be looking for clues about dark energy--the mysterious force that is accelerating the expansion of the universe. Another objective of the mission will be finding and studying exoplanets. WFIRST uses the same 2.4 meter telescope size as Hubble, but with 18 cutting-edge fourth-generation image sensors compared to Hubble
