Square image filled with blue, white, yellow, and red points of light of different size and brightness, most of which are stars. The larger and brighter stars show Webb’s distinctive diffraction pattern consisting of eight spikes radiating from the center. At the lower right is a scale bar labeled 2 light-years. The scale bar is two-ninths the width of the image, and shows that throughout the image, the distance between adjacent stars is a fraction of one light-year. The density of stars and brightness of the image is greatest in the upper left portion of the image where the stars are much closer together, and decreases gradually toward the bottom right where they are farther apart. The number of larger, brighter stars also appears to decrease from the upper left toward the lower right.

Detail of the globular cluster M92 captured by Webb's NIRCam instrument. This field of view covers the lower left quarter of the right half of the full image. Globular clusters are dense masses of tightly packed stars that all formed around the same time. In M92, there are about 300,000 stars packed into a ball about 100 light-years across. The night sky of a planet in the middle of M92 would shine with thousands of stars that appear thousands of times brighter than those in our own sky. The image shows stars at different distances from the center, which helps astronomers understand the motion of stars in the cluster, and the physics of that motion.
