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: 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/

#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.”

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.”

Bright stars are scattered throughout the clouds, with the densest cluster situated in the center.
