#NASAWebb has pinpointed the host galaxy of the most distant fast radio burst ever seen. The galaxy proved surprisingly small and young, which provides a clue to the source of the burst: https://news.stsci.edu/4hEmZip 🔭

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

#NASAWebb peered into the Flame Nebula, locating the faint infrared signatures of several brown dwarfs, objects so small that their cores will never sustain nuclear fusion of hydrogen. The smallest among them is two to three times the mass of Jupiter: https://bit.ly/4iZyqC8 🔭

A collage of four images showing a dusty nebula. Two-thirds of the collage is taken up by a single image of the nebula, while the remaining third shows three insets stacked on top of each other. In the largest image at left, there is an orange and yellow fang-like cloud of matter that cuts this section in two. The top side of the fang shows more clouds of a dark brown shade, while the bottom shows filaments of light brown. There are a number of bright blue and red points of light spread throughout, three of which are circled in white and labeled with a number from one to three. Circle 1 is located at about 9 o’clock in the middle of the fang-like cloud, while Circle 2 is at about 2 o’clock and Circle 3 is located at about 4 o’clock, toward the bottom left. Each circle magnifies an individual object, which is shown in the three squares to the right, labeled 1 to 3 from top to bottom. Each image contains a single, fuzzy point of light in the middle.

NEW: The contrasting colors in NGC 7129 show differences in temperatures detected by #NASAWebb. The gold cavity at the left is hottest due to the central star and other embedded stars. The clumpy, red matter is colder and represents jets from less mature protostars: https://news.stsci.edu/3U8T7Bz 🔭

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

NEW: A surprising chemical clue has broken open a Hubble cold case from 1999. Astronomers now suspect the mystery signatures in the data are from a second-generation planet that formed from gas and dust ejected by a dying star: https://news.stsci.edu/46WpciV 🔭

Illustration labeled Artist’s Concept at bottom right. A gaseous planet in the right foreground, seen mostly in silhouette, orbits a small, white star in the background at left. The star is surrounded by a thin, bright white disk tilted from lower left to upper right. A semi-transparent tail of material comes off the planet toward upper right. Distant stars dot the black background of space.

#NASAWebb has provided a crash course on planet-shattering collisions, providing clues to the amount of energy in their collisions. (1/6) 🧵 🔭 🧪

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.”

Astronomers theorize that the black hole at the center of Centaurus A influences the region as it feeds and launches powerful outflows. Learn more about the impact of its central black hole with a printable poster of this observation from #NASAWebb: https://go.nasa.gov/4hwsDlf

A horizontally oriented poster with an image of Centaurus A against a black background. The galaxy is brightest at its center, where a brilliant white and pink glow radiates outward. Wispy, ‘S’-shaped ribbons of pink arc above and below the center of the image. A parallelogram-shaped band of gray and white dust cuts across the middle of the galaxy. The galaxy’s outer edges fade into soft textures that stretch toward the left and right sides of the image. Along the bottom is a series of thin vertical bars ranging from purple at left to blue, green, yellow, orange, and red at right. Bars are separated slightly, with black in between. Bar colors are brightest at the bottom, fading up to black. Brightness varies from bar to bar, giving the array an undulating feel. At upper right is text that reads, “National Aeronautics and Space Administration” and NASA’s blue, white, and red meatball insignia. Title text appears at lower left that says, “James Webb Space Telescope: Centaurus A.”

A large, long portion of one of the spiral arms in spiral galaxy Messier 51. Red-orange, clumpy filaments of gas and dust stretch in a chain from left to right to comprise the arm. Shining cyan bubbles light up parts of the gas clouds from within, and gaps expose bright star clusters in these bubbles as glowing white dots. The whole image is dotted with small, point-like stars. A faint blue glow around the arm illuminates the otherwise dark background.

Astronomers estimate that there are 500,000 stars within this #NASAWebb image of Sagittarius C. One of the most densely packed areas lies within the dark, U-shaped region at the top left of the cyan-colored cloud of ionized hydrogen: https://bit.ly/4zeme64

A funnel-shaped region of space appears darker than its surroundings with fewer stars. It is wider at the top edge of the image, narrowing toward the bottom. At the bottom, a small clump of red and white appears to shoot out streamers upward and left. A large, bright, cyan-colored area surrounds the lower portion of the funnel-shaped dark area, forming a rough U shape. The cyan-colored area has needle-like, linear structures and becomes more diffuse in the center. The right side is dominated by clouds of orange and red, with a purple haze. There are thousands of pinpoints of light, a multitude of stars, throughout the view.
