Here we see both HH 901 (top) and 902, with their jets spouting lest and right. Some explanation on the filters by chatGPT in the Alt Text.

$chatGPT: HH 901 appears near the upper left as a tall, narrow pillar of brown dust rising from a larger cloud. At its tip, a deeply embedded young star drives a pair of narrow blue jets in opposite directions, extending left and right into the surrounding gas. Near the lower center, HH 902 emerges from another dense pillar, also producing opposing blue jets that pierce the surrounding nebula. The image uses color to isolate different emissions: blue represents the difference between the F150W2 and F164N filters, highlighting shocked iron emission in the jets; green shows the broadband F444W image; and red represents the difference between the F444W and F470N filters, emphasizing warm dust and molecular gas. The surrounding nebula glows in soft green and yellow, with dense brown cloud tops outlining sculpted pillars and globules. Numerous bright foreground stars with blue diffraction spikes are scattered across the field, contrasting with the delicate jets and intricate cloud structures carved by ongoing star formation.$

Here I stretched the colors differently for the 6 panels

A JWST 🔭 follow-up on HST detail of HH 901 and neighbours. The Hubble image is below. I did not resize or realign. Credit: NASA, ESA, CSA, STScI.

$chatGPT: A collage of six James Webb Space Telescope NIRCam images highlighting Herbig–Haro object HH 901 and nearby structures within the Carina Nebula. The upper left panel shows HH 901: a dense, finger-like pillar of brown dust extending upward from a larger cloud, with a bright young star emerging from its tip and driving a narrow, bluish jet into the surrounding nebula. The large upper-center panel depicts a neighboring section of the nebula, where towering walls of yellow-green gas and dust are sculpted into ridges and cavities by intense stellar radiation. The remaining four panels show other nearby features rather than HH 901 itself, including slender dust filaments, isolated globules, curved cloud edges, and intricate pillars with rounded tips. Throughout the collage, bright foreground stars with diffraction spikes punctuate the glowing clouds, while the close-up views emphasise the rich variety of shapes carved into the nebula by newborn stars and powerful stellar winds.$

JWST 🔭 has been releasing data for HH object in the Carina Nebula, check the bot for latest releases. Here I put them near each other, + some older data. Below I show in context the HST image Credits: NASA, ESA, CSA, STScI.

*Survay, not source. Got it, the orange "star" in the top right corner is a galaxy. A quasar. I guess it has spikes because it is brighter than the usual galaxy

$A document with the coordinates and a DS9 snapshot showing the coordinates in the image. A close-up shows the distant galaxy as a bright orange point with short diffraction spikes.$

LEDA 1064923 by JWST 🔭. I think DES stands for Dark Energy Source, but I can't pinpoint the object in the larger image

A noisy image, a small segment cropped from the quoted larger image. It depicts a grey, long galaxy shape with a bright core. Some smaller, remote galaxies dot the background in orange and white.

We are at the white squares. Not much of Andromeda (M 31) has been covered by JWST 🔭 so far. The top right satellite galaxy is M 110.

chatGPT:
A preview image from the MAST archive showing the Andromeda Galaxy (M31) overlaid with footprints of James Webb Space Telescope observations. The large spiral galaxy stretches diagonally across the frame, with its bright central bulge near the middle and broad, dusty spiral arms fading toward the lower right. A magenta crosshair marks the center of the currently selected observation. White outlined detector footprints indicate the field of view of the selected JWST image, positioned just above and to the left of the galaxy's nucleus. Additional observations are shown as orange outlined footprints scattered across the galaxy and nearby sky, including several overlapping fields along the inner disk, one on the small companion galaxy M32 to the upper right, and others farther from the main galaxy. The overlay illustrates how the selected image fits into the broader set of JWST observations of Andromeda.

Another visualisation of JWST🔭 data from "Mab area", in the vicinity of the supernova remnant Cassiopeia A. Here we see older light from 2024 summer in red, newer light reaching us on Dec 2024 as green, and Jul 2025 as blue. Credits: NASA, ESA, CSA, STScI.

chatGPT:
A false-color James Webb Space Telescope image of light echoes surrounding the supernova remnant Cassiopeia A. Broad, translucent ribbons of dust sweep diagonally from the upper left to the lower right, displaying a vivid rainbow of colors. Unlike a natural-color image, the colors encode time: red marks light that reached the telescope earlier, while green and blue indicate progressively later-arriving light. This creates layered bands that trace the outward motion of the supernova's light pulse as it illuminates interstellar dust at different distances.

Yuval Harpaz 𝚿👨‍🎓 📊🌌🔭 @yuvharpaz· 25d

one more take, here I summed the light from all 6 frames, then stretched a bit.

$chatGPT: A James Webb Space Telescope NIRCam image of light echoes surrounding the supernova remnant Cassiopeia A. Wispy orange filaments sweep diagonally across the frame from the upper left to the lower right, resembling translucent ribbons of smoke or flowing silk. These glowing structures are clouds of interstellar dust illuminated by the outward-moving flash from the long-ago supernova explosion, revealing intricate ripples, folds, and turbulent strands. Near the upper left, a bright foreground star with long diffraction spikes sits embedded within the brightest dust cloud, while dozens of other blue-white stars sparkle across the field. Numerous distant galaxies appear as tiny golden smudges and elongated ovals scattered between the stars. The image is a mosaic, with faint seams visible where overlapping observations were stitched together, especially near the edges. The overall scene contrasts the delicate, glowing dust echoes with the sharp stars and distant galaxies beyond.$

Here I am following @melina-iras07572.bsky.social , tracking the light echo by time. The first 4 frames were captured a few weeks apart between 19 Aug and 16 Oct 2024. Then there is a 2.5 month leap to Dec 2024, and then all the way to Jul 2025. I don't understand light echo. Credits below 🔭.

NGC-5253 by JWST 🔭. Here I added MIRI (red) from a previous visit to two newly released NIRCam filters. Credits listed by the bot below

$chatGPT: The galaxy fills the center of the frame as a brilliant white-pink core surrounded by a diffuse, irregular glow. Long, bright red diffraction spikes radiate from the saturated central star cluster, extending nearly to the edges of the image. Wispy filaments and clumps of pink and red dust spread outward in all directions, tracing turbulent gas sculpted by intense star formation. Countless foreground stars and distant background galaxies are scattered across the field, appearing as blue-white points, yellow-orange stars, and tiny elongated galaxies$

A selfie of sorts, I see the shadow of the secondary on the primary mirror science.nasa.gov/wp-content/u...

Another last one, MIRI

last one, this is so pretty I have to restrain myself.

Yuval Harpaz 𝚿👨‍🎓 📊🌌🔭 @yuvharpaz· Jul 8

Here I assign green to filters f200w and f187n alternately. For this galaxy, the f187n filter captures star forming regions.

More from Centaurus A, Here I combined MIRI (red) with NIRCam. 🔭 NASA, ESA, CSA, STScI Alt text by chat GPT

The galaxy's bright white central bulge dominates the middle of the image, surrounding a compact, luminous active nucleus powered by a supermassive black hole. Cutting vertically through the center is the galaxy's famous dust lane, transformed into a complex web of glowing orange and deep red filaments by the addition of MIRI data. The smooth halo of older stars fades gradually into the dark background, which is dotted with foreground stars and distant galaxies.

Just playing with DS9. Can't I make bab pixels transparent?

chatGPT:A wide infrared mosaic of the nearby galaxy Centaurus A stretches across the frame, assembled from multiple overlapping observations. A broad, luminous band of stars and interstellar material runs horizontally through the center, marking the galaxy's prominent dust lane. Near the middle, an intensely bright, compact core shines with a pinkish-white glow, representing the active galactic nucleus powered by a supermassive black hole. Surrounding the core are intricate filaments, wisps, and loops of dust in shades of tan, brown, and pale gold, revealing the turbulent structure of the galaxy's central regions. Numerous bright knots scattered along the dust lane indicate sites of active star formation.
