Webb identified the host galaxy of the most distant fast radio burst yet

NASA says the James Webb Space Telescope found an actively star-forming dwarf galaxy 1,000 times less massive than expected.

$A field full of small galaxies of all shapes against the blackness of space. A few bright white stars show 8 prominent diffraction spikes. A small galaxy at lower right is highlighted with a white box. A shaded triangle extends upward to the corners of a larger box showing a zoom in of the region. Two fuzzy, light blue blobs are at center, with a larger and brighter one at top. Just above the top blob is a white crosshair showing the location where a fast radio burst was detected.$

NASA Webb teases a new image in World Space Week post

NASA Webb said in an X post for World Space Week that people searching for space facts might come across the telescope’s newest image, but the post itself did not include details about the image.

$A young star cluster filled with many stars that display Webb’s unique eight-pronged diffraction pattern. At its center is a yellow star which sports the largest diffraction pattern. To the left of the star, there is a region filled with yellow dust and gas that extends from the star to the left border of the image. This yellow region extends from the bottom, covering about two-thirds of the image. The yellow region has several blue stars of different sizes embedded within. The top third, which lies outside of the yellow region, holds a few bright protostars, within dense gray gas. Those stars illuminate the gas, making it appear blue. A few red outflows from other protostars are visible above this grayish-blue region. To the right of the central star, there is a clumpy, flame-like plume of red dust and gas with protostars that emit a soft white light within. The plume is surrounded by more dense gray gas and dust.

Webb study of rare extreme debris disks points to two kinds of planet-shattering collisions

Webb and Spitzer observations of 21 rare extreme debris disks found silica-rich and silica-poor groups that may reflect different collision energies in young stellar systems.

Artist’s concept of a star and its debris disk against the black background of space. The star is in the background, right of center, and depicted as a small, luminous sphere. The debris disk is a large blue ring that encircles the star. The debris disk is angled toward the viewer, so that the portion nearest to the viewer extends beyond the bottom frame of the illustration. Many dark, rocky fragments are scattered throughout the debris disk. In the foreground, toward the left, is a small planetary embryo colliding into the left side of a larger spherical object. The impact site glows bright yellow and orange and has a mottled appearance, as though chunks of both colliding bodies are breaking up and being destroyed. Orange-yellow streams of vapor extend outward from the collision area. Behind the debris disk and its star are many small stars in the background. A label in the bottom right corner reads “Artist’s Concept.”
