NASA Webb Pushes Boundaries of Observable Universe Closer to Big Bang

28 January 2026

NASA’s James Webb Space Telescope has topped itself once again, delivering on its promise to push the boundaries…

Six Hubble images of distorted galaxies are organized in a two-row mosaic. From left to right, the top row of galaxies appears as follows: The left panel has a galaxy that resembles the number nine tilted on its side to the left and has red-orange regions scattered with blue knots. The center square shows an edge-on spiral galaxy appearing like a white thin bar extending from 8 ou2019clock to 2 ou2019clock. It has a bright, compact core and a small background spiral galaxy just below the core. The right panel shows two merging galaxies forming a convoluted shape that extends from 8 ou2019clock to 2 ou2019clock. The bottom row of galaxies appears as follows: Left square contains a face-on spiral with faint, broad arcs of material to its left and right. The center panel has a hazy white, face-on spiral with a lumpy vertical line to its right that appears to curve around its core. The right panel shows an orange elliptical galaxy with a lumpy blueish galaxy curving around it to the right.

$Image shows a large spiral galaxy that that has a bright white center, with several lanes of reddish-brown dust and gas in between faint white arms. The galaxy takes up the center third of the frame. There are several thousand stars, some with diffraction spikes, scattered around the image. This image is labeled Hubble. A small box outlining an area at the center of the galaxy leads a pullout square at the top right. The image, labeled Webb, is dark with a white glowing oval at the center.$

A region of space is filled with stars and clumps of glowing orange and tan dust. A small portion of the sky at the center of the image is outlined with a white box. Lines extend from the corner of the box to the inset panel at the top right showing a magnified version of the outlined portion of the image. In the inset, there are smatterings of dim whitish-blueish stars and about seven glowing red orbs across the center in a line. Also across the center of the inset is a green glow. The background of the image is filled with stars and galaxies of various shapes and colors.

James Webb Space Telescope image showing a broad area of space with many small galaxies, four of which are highlighted in pull-out boxes. The four highlighted galaxies are very small, appearing as points of light. Black areas of the overall image indicate where the telescope did not collect data - a vertical section in the center and a square in the lower left corner.

An illustration of the red supergiant star Betelgeuse, its companion star, and a dusty wake. The disk of a red-orange star is in the center. It is surrounded by a diffuse orange cloud representing its extended atmosphere. Below it about one stellar diameter away is a yellow dot representing a smaller companion star. From the companion, a dark red cloud wraps around in a counterclockwise direction. It begins very narrow and expands as it gets further from the companion, finally disappearing at the outer edge of the diffuse orange cloud around 10 ou2019clock. The words u201cartistu2019s conceptu201d are at lower right.
