Paper abstract: We study the rest-frame optical and ultraviolet morphology of galaxies in thefirst billion years of the Universe. Using JWST data from the UNCOVER andMegaScience surveys targeting the lensing cluster Abell 2744 we presentmulti-band morphological measurements for a sample of 995 galaxies selectedusing 20-band NIRCam photometry and 35 using NIRSpec Prism spectroscopy overthe redshift range of 4
