Image of galaxy cluster SMACS 0723, affectionately known as Webb’s First Deep Field, captured by Webb’s Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI), with compass arrows and color key for reference.

The north and east compass arrows show the orientation of the image on the sky. Note that the relationship between north and east on the sky (as seen from below) is flipped relative to direction arrows on a map of the ground (as seen from above).

This image shows invisible near- and mid-infrared wavelengths of light that have been translated into visible-light colors. The color key shows which NIRCam and MIRI filters were used when collecting the light. The color of each filter name is the visible light color used to represent the infrared light that passes through that filter.

Because this is a deep field that shows objects at various distances and magnifications, there is no scale bar.
