galaxy_cluster A candidate for a galaxy at z≈9.6, magnified by a factor of ~15 by the foreground cluster MACSJ1149+2223 (z ≈ 0.54). The object was found in an HST survey using the WFC3IR camera (Zheng et al. 2012). This young object is seen when the universe is only about 500 million years old.
 microlensing search area.jp The area around another star that WFIRST will search (in blue) for exoplanets compared to Kepler's search area.
 wfirst vs hubble. The field of view of the Hubble Space telescope compared to WFIRST.
 microlensing technique WFIRST will search for exoplanets using the microlensing technique displayed above. As a lens star moves across the line of sight of the telescope, an exoplanet will magnify a background star's signal.
