Galaxy cluster SMACS 0723, affectionately known as Webb’s First Deep Field, captured by Webb’s Near-Infrared Camera (NIRCam), with compass arrows and color key for reference. All images taken by Webb show invisible near-infrared wavelengths of light that have been translated into visible-light colors. The color of each filter name is the visible light color used to represent the infrared light that passes through that filter. [NASA, ESA, CSA, STScI]
