📷 This NASA/ESA/CSA James #Webb Space Telescope image shows NGC 346, one of the most dynamic star-forming regions in nearby galaxies, and the study of which recently solved a puzzle by proving a controversial finding made using NASA/ESA #Hubble over 20 years ago! www.esa.int/Science_Expl... 🔭🧪

🧵 This breathtaking image from #JWST, published last April 29, depicts a cosmic field filled with thousands of galaxies. THOUSANDS OF GALAXIES! Stars, marked by diffraction spikes, are within the Milky Way. Reference➡️ esawebb.org/images/potm2... 🔭 🧪 #stellarastro #cosmology #Universe #Webb

The image shows an area of deep space teeming with thousands of galaxies, like a bright mosaic on a deep black background. In the center, slightly lower, stands out a group of gold-white galaxies that shine brightly, like a cluster of gems. Around them, galaxies of various shapes dot the scene: some are spirals with curved arms, others are elliptical and smooth, still others have distorted shapes. The colors vary from white and blue for nearby galaxies to red for distant ones. Stars of the Milky Way appear as bright points with thin rays radiating outward, like small sparkling spikes. The overall effect is a dense and vibrant cosmic carpet, full of light and movement.

#OTD: 25 December 2021, a perfect launch on #ChristmasDay for the NASA/ESA/CSA James #Webb Space Telescope on #Ariane5 flight VA256 from Europe’s Spaceport in Kourou, French Guiana 🧪🔭 👉 esawebb.org/images/webb_... @esa.int @science.esa.int @stsci.edu

The James Webb Space Telescope lifted off on an Ariane 5 rocket from Europe’s Spaceport in French Guiana, at 13:20 CET on 25 December 2021 on its exciting mission to unlock the secrets of the Universe.

🆕 This new NASA/ESA/CSA James #Webb Space Telescope image shows a rare cosmic phenomenon called an 'Einstein ring' 🧪🔭 www.esa.int/ESA_Multimed... @science.esa.int @spacetelescope.bsky.social

In the centre is an elliptical galaxy, seen as an oval-shaped glow around a small bright core. Around this is wrapped a broad band of light, appearing like a spiral galaxy stretched and warped into a ring, with bright blue lines drawn through it where the spiral arms have been stretched into circles. A few distant objects are visible around the ring on a black background.

🆕 This NASA/ESA/CSA James #Webb Space Telescope view of planetary nebula NGC 6072 in the near- and mid-infrared shows the very final stages of life of the star at its centre, expelling shells of material and losing up to 80% of its mass 🧪🔭 🔗 esawebb.org/news/weic2514/ @stsci.edu @science.esa.int

Colourful mostly red image of near-infrared light from a glowing cloud with a distorted, asymmetrical shape, illuminated from within by a bright central star. The asymmetrical shape resembles paint splattered on the ground. In the centre of this image, a light blue glow casts over areas of dark pockets that appear dark blue and are traced with orange material. It has a clumpy appearance. The shells become a deeper red with distance from the centre. The shells appear as lobes that push gas toward the equatorial plane, forming a disc. The background of the image is black and speckled with tiny bright stars and distant galaxies.

😵 Be ready to be amazed! The NASA/ESA/CSA James #Webb Space Telescope brings you the "Cosmic Tornado" 🌪️ Webb observations have also revealed the identity of the fuzzy object at the tip of this object also known as Herbig-Haro 49/50. Read more 👉 www.esa.int/Science_Expl... 🔭 🧪 ☄️

Angled from the upper left corner to the lower right corner of the image is a conical shaped orange-red cloud known at Herbig-Haro 49/50. This feature takes up about three-fourths of the length of this angle. The upper left end of this feature has a translucent, rounded end. At this same location there is a background spiral shaped galaxy with a concentrated blue center that fades outwards to blend in with red spiral arms. The conical feature widens slightly from the rounded end at the upper right down to the lower right. The black background of space is clearer, speckled with some white stars and smaller, more numerous, fainter white galaxies.

Webb apre uno scrigno pieno di stelle #webb @[email protected] @[email protected] Questa Immagine del Telescopio Spaziale James Webb ci trasporta in un regno fantastico all’interno della nostra galassia, dove la luce penetrante delle stelle e i venti […] [Original post on mastodon.uno]

L'elemento evidenziato nell'immagine, opportunamente chiamato "Il Forziere" (Treasure Chest), sembra trovarsi nel suo ambiente naturale in questo giardino di sculture celesti. Il Forziere è quello che viene definito un "globulo cometario": una nube isolata di gas e polvere con una testa densa e scura e una coda ampia. Queste nubi spesso ricordano vagamente le comete, ma il Forziere assomiglia distintamente a un baule di legno con il coperchio spalancato.

Tuttavia, questo forziere non contiene gioielli o monete d'oro, bensì un ammasso compatto di giovani stelle. Queste stelle sono responsabili del bagliore ultraterreno che proviene dall'interno del Forziere, rivelato dalla sensibile Near-Infrared Camera (NIRCam) di Webb. I ricercatori stimano che l'ammasso del Forziere contenga circa 70 stelle, la più massiccia delle quali è una rara stella di tipo O, circa 19 volte più massiccia del Sole.

L'ammasso stellare ha probabilmente circa 1,3 milioni di anni, sebbene stime precedenti lo indicassero giovane appena 100.000 anni. A causa della sua giovinezza, l'ammasso è ancora profondamente immerso nelle nubi polverose del Forziere. Anche le singole stelle dell'ammasso sono avvolte dalla polvere; gli astronomi hanno trovato prove che molte di queste stelle siano circondate da dischi circumstellari. Col tempo, la brillante luce di queste giovani stelle disperderà la nube circostante, rivelando l'intero ammasso.

The James Webb Telescope Is Changing Astronomers’ Understanding of the Ancient Cosmos

From how galaxies form to the beginnings of the universe, the images from the space telescope are giving cosmologists new data to explore—and theories to build out.
