![]() ![]() This slice of the vast universe is approximately the size of a grain of sand held at arm’s length by someone on the ground. ![]() Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. ![]() Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail. NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. These are images of background galaxies that have been stretched and distorted by the foreground galaxy cluster. They follow invisible concentric circles that curve around the center of the image. There are also many thin, long, orange arcs. In the center of the image, between 4 o’clock and 6 o’clock in the bright star’s spikes, are several bright, white galaxies. It has eight blue, long diffraction spikes. Some look as large as the galaxies that appear next to them.Ī very bright star is slightly off center. Most appear blue with diffraction spikes, forming eight-pointed star shapes. In front of the galaxies are several foreground stars. Most appear as fuzzy ovals, but a few have distinctive spiral arms. Some are shades of orange, others are white. Thousands of small galaxies appear across the image. They include foreground stars, galaxies in a galaxy cluster, and distorted background galaxies behind the galaxy cluster. This image shows many overlapping objects at various distances. ![]()
