James Webb Space Telescope posted a photo:
On July 12, 2026, we celebrated four years of Webb science! And what a time it has been! We've learned so much about our universe and ourselves.
Here are some of our favorite images and most interesting science results in the form of a little retrospective in six parts, by year, which we will link in all the captions below. Each collage highlights science from the main science themes: Early Universe, Other Worlds, Galaxies, and Star Lifecycles.

July 12, 2022, Webb’s first images. Clockwise ->
The “Cosmic Cliffs” of the Carina Nebula, a star-forming region.
The Southern Ring Nebula in mid-infrared, now known to have two stars at its center, a dying star and a partner, both shaping the nebula’s intricate rings.
WASP 96-b spectrum, showing this planet to be large and hot with a “puffy” atmosphere, orbiting very close to its Sun-like star.
Stefan’s Quintet of galaxies in the near-infrared. Four of these five galaxies are colliding, stretching and pulling on each other: two in the middle, one toward the top, and one toward the bottom. The one to the upper left is actually much closer to us.
Galaxy Cluster SMACS 0723, the first image released by Webb, and the deepest and sharpest image of the early universe ever taken as of its release. Thousands of galaxies appear all across the view with varying colors and shapes. Long orange arcs appear at left and right toward the center; these are distant galaxies being warped by the extreme gravity of the galaxy cluster in front of it.
The Southern Ring Nebula but in the near-infrared.
