An image of the GOODS-South field as observed by JWST. More than 45,000 galaxies are visible here.

An image of the GOODS-South field as observed by JWST. More than 45,000 galaxies are visible here. In this image, blue, green, and red were assigned to Webb’s NIRCam (Near-Infrared Camera) data at 0.9, 1.15, and 1.5 microns; 2.0, 2.77, and 3.55 microns; and 3.56, 4.1, and 4.44 microns (F090W, F115W, and F150W; F200W, F277W, and F335M; and F356W, F410M, and F444W), respectively.
