Webb Telescopes view face-on of spiral galaxy NGC 4254.
Webb launches on a cloudy day from an Arianne 5 rocket. The image shows the rocket just lifting off the pad with a plume of orange fire and a plume grey blue smoke extending well to the right against a slate blue sky.

Webb Telescope Latest News

Webb's latest news releases in reverse chronological order going back to 2012.

Left: Messier 82 as imaged by NASA's Hubble Space Telescope. Hour-glass-shaped red plumes of gas are shooting outward from above and below a bright blue, disk-shaped center of a galaxy. This galaxy is surrounded by many white stars and set against the black background of space. A small square highlights the section that the image on the right shows in greater detail. White text at bottom reads "Hubble." Right: A section of Messier 82 as imaged by NASA's James Webb Space Telescope. An edge-on spiral starburst galaxy with a bright white, glowing core set against the black background of space. A white band of the edge-on disk extends from lower left to upper right. Dark brown tendrils of dust are scattered thinly along this band. Many white points in various sizes – stars or star clusters – are scattered throughout the image, but are most heavily concentrated toward the center. Many clumpy, red filaments extend vertically above and below the galaxy’s plane. White text at bottom reads "Webb."

An image of a region of a molecular cloud. The orange cloud is dense and bright close to the top of the image, like rolling clouds, and grows darker and more wispy toward the bottom and in the top corner. One bright star with six short diffraction spikes and several dimmer stars are visible as light spots among the clouds.

A spiral galaxy with a small bar of bright-white stars at its core. Two main spiral arms extend outward from each end of the bar. They appear to fork into multiple branches beyond the galaxy's core. The spiral arms have a lavender hue. Bright-white and bright-red stars dot the galaxy. Reddish-brown dust lanes line the inner curves of the spiral arms.

NASA’s Webb, Hubble Telescopes Affirm Universe’s Expansion Rate, Puzzle Persists

NASA’s Hubble and James Webb Space Telescope have tag-teamed to produce definitive measurements of the universe's expansion rate.

At the center of the image is a nebula on the black background of space. The nebula is comprised of clumpy, red, filamentary clouds. At the center-right of the red clouds is a large cavernous bubble, and at the center of the bubble there is an opaque blueish glow with speckles of stars. At the edges of the bubble, the dust is white. There are several other smaller cavernous bubbles at the top of the nebula, including two tiny cavities at the top center of the image. There are thousands of stars that fill the surrounding area outside the nebula, most of them are yellow or white. At 11 o’clock and 6 o’clock there are extremely bright stars with 8 diffraction spikes. There are also some smaller, red stars and a few disk-shaped galaxies scattered across the image.

Two side-by-side images of the same region of space. Superimposed on each is a simple, white line drawing of a telescope. Left: Drawing of the Hubble Space Telescope on a Hubble image showing numerous stars and a hazy blue to brown cloud of gas and dust. Right: Drawing of the Webb Space Telescope on a Webb image showing numerous stars and a pinkish yellow to brown cloud of gas and dust. The Webb image shows a more filamentous and billowy structure. There is no clear boundary between the two images.

A rectangular image with thousands of galaxies of various shapes and colors on the black background of space. Some are noticeably spirals, either face-on or edge-on, while others are blobby ellipticals. Many are too small to discern any structure. One prominent foreground star at top center features Webb’s signature 8-point diffraction spikes. At lower right, a small region is highlighted with a white box. Vertical lines extend upward like a cone to the bottom corners of a larger box at upper right, showing a zoomed in version of the highlighted area. The pullout features a galaxy labeled GN-z11, seen as a fuzzy yellow dot. Above it is another galaxy, seen as a fuzzy red oval.

A three-panel image of a supernova remnant. The left panel is labeled “NIRCam” while the two right panels are labeled “MIRI M R S Argon two” (at top) and “NIRSpec I F U Argon six” (at bottom). At left, a mottled light pinkish-orange oval whose inner edge resembles a string of pearls. Within the oval is a dense blue-green cloud, shaped like a keyhole. Three stars with six-point diffraction patterns surround the oval. Above and below these structures, are very faint orange rings, which form a figure eight pattern. The center of the supernova remnant is surrounded by a white box with lines leading to the upper and lower right of the image, where two stacked panels show a bright orange ring with an orange dot in the middle. The upper panel is fuzzier and more blobby, while the bottom panel has more clearly defined edges around the ring and central dot.

Nineteen Webb images of face-on spiral galaxies are combined in a mosaic. Some appear within squares, and others horizontal or vertical rectangles. Many galaxies have blue hazes toward the centers, and all have orange spiral arms. Many have clear bar shaped-structures at their centers, but a few have spirals that begin at their cores. Some of the galaxies’ arms form clear spiral shapes, while others are more irregular. Some of the galaxies’ arms appear to rotate clockwise and others counterclockwise. Most galaxy cores are centered, but a few appear toward an image’s edge. Most galaxies appear to extend beyond the captured observations. The galaxies shown, listed in alphabetical order, are IC 5332, NGC 628, NGC 1087, NGC1300, NGC 1365, NGC 1385, NGC 1433, NGC 1512, NGC 1566, NGC 1672, NGC 2835, NGC 3351, NGC 3627, NGC 4254, NGC 4303, NGC 4321, NGC 4535, NGC 5068, and NGC 7496.
