This image of the Sagittarius B2 (Sgr B2) molecular cloud, captured by the NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope includes compass arrows, scale bar, and color key for reference.
To create this image, near-infrared wavelengths of light have been translated into visible-light colors. The color key at the bottom shows which NIRCam filters were used, and which visible-light color was assigned to that filter.
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).
