Abstract: We report the discovery of four galaxy candidates observed 450?600 Myr after the Big Bang with photometric redshifts between z ? 8.3 and 10.2 measured using James Webb Space Telescope (JWST) NIRCam imaging of the galaxy cluster WHL0137?08 observed in eight filters spanning 0.8?5.0 ?m, plus nine Hubble Space Telescope filters spanning 0.4?1.7 ?m. One candidate is gravitationally lensed with a magnification of ? ? 8, while the other three are located in a nearby NIRCam module with expected magnifications of ? ? 1.1. Using SED fitting, we estimate the stellar masses of these galaxies are typically in the range log M M? ? = 8.3?8.7. All appear young, with mass-weighted ages < 0.15 mag, and specific star formation rates sSFR ?0.25?10 Gyr?1 for most. One z ? 9 candidate is consistent with an age
