1/ 🆕 Webb reaches new milestone 📍 in the quest for distant galaxies, having discovered some that date back to less than 400 million years after the #BigBang 🎇 The light from these galaxies has taken more than 13.4 billion years to reach us. 
2/ “It was crucial to prove that these galaxies do, indeed, inhabit the early universe. It’s very possible for closer galaxies to masquerade as very distant galaxies,” said astronomer and co-author Emma Curtis-Lake from @UniofHerts UK
@UniofHerts 3/ The observed region in this image is 15 times larger than the deepest infrared images produced by @HUBBLE_space yet is even deeper and sharper at these wavelengths.
1/ 🆕 The Southern Ring Nebula comes into new view, as we combine near- and mid-infrared light from three filters from the Near-Infrared Camera #NIRCam and Mid-Infrared Instrument #MIRI on Webb. Read on 🧵👇
2/ In this image, Webb’s image of the Southern Ring Nebula highlights the very hot gas that surrounds the central stars. This hot gas is banded by a sharp ring of cooler gas, which appears in both images.
3/ In this image, Webb traces the star’s scattered outflows that have reached farther into the cosmos. Most of the molecular gas that lies outside the band of cooler gas is also cold. It is also far clumpier. Read about these images here: esawebb.org/images/souther…
1/ 🆕 Webb has captured a portion of the dwarf galaxy Wolf–Lundmark–Melotte (WLM) using #NIRCam. The image demonstrates Webb’s remarkable ability to resolve faint stars outside the Milky Way.
2/ The galaxy lies roughly 3 million light-years away and was selected for observations as its gas is similar to that which made up galaxies in the early Universe.
3/#WebbSeesFarther This image shows this portion of the dwarf galaxy captured by Spitzer's Infrared Array Camera (left) and Webb's Near-Infrared Camera (right) 🆒
1/ This new Webb picture of the month shows IC 1623, a pair of interacting galaxies, plunging into one another. Their collision has ignited a spate of star formation creating new stars at a rate above 20 times that of the Milky Way. Read more 👉 esawebb.org/images/potm221… and 👇
2/ Astronomers used Webb's #MIRI, #NIRSpec, and #NIRCam instruments to investigate IC 1623. This will allow scientists to unravel the interactions in galactic ecosystems. These observations are also accompanied by data from other observatories, like @HUBBLE_space #BFFinSpace
@HUBBLE_space 3/ The luminous core of this merger is very bright and highly compact, so much so that Webb’s diffraction spikes appear atop the galaxy in this image. The 8-pronged diffraction spikes are created by the interaction of starlight with the physical structure of the telescope.
This detailed new image taken by #Webb peers into the chaos of the Cartwheel Galaxy 🛞 The image unveils secrets about star formation ✨ & the galaxy’s central black hole, providing new insights into a galaxy in the midst of a slow transformation 👇
The Cartwheel Galaxy, located about 500 million light-years away in the Sculptor constellation, looks much like the wheel of a wagon. Its appearance results from a high-speed collision between a large spiral galaxy and a second smaller galaxy 👇
Telescopes like @HUBBLE_space have previously examined the Cartwheel, but our view of the galaxy has been obscured by gas and dust 😶🌫️ Webb, with its infrared imaging capabilities, has now uncovered new insights into the galaxy’s nature 👇
📢 #Webb reveals cosmic cliffs & glittering landscape of star birth, showing us emerging stellar nurseries & individual stars that were previously obscured. This is the edge of nearby star-forming region NGC 3324 in the Carina Nebula. Read more here: esawebb.org/news/weic2205/ or👇
Called the Cosmic Cliffs, Webb’s seemingly 3D picture looks like craggy mountains on a moonlit evening. In reality, it is the edge of the giant, gaseous cavity within NGC 3324, and the tallest “peaks” in this image are about 58 light-years high 👇
The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the centre of the bubble, above the area shown in the image 👇
📢 #Webb delivers deepest image of the Universe yet, looking far back in time when the Universe was less than a billion years old. The image is about the size of a grain of sand held at arm’s length, yet it reveals thousands of galaxies. Read more esawebb.org/news/weic2209/ or 👇
This is Webb’s First Deep Field, the deepest, sharpest infrared image of the distant Universe so far. It shows galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago, with many more galaxies in front of and behind the cluster 👇
The combined mass of this galaxy cluster acts as a gravitational lens 🔎 magnifying more distant galaxies, including some seen when the Universe was less than a billion years old 👇
1/ 📢 This is an image mosaic of 18 randomly organised dots of starlight, the product of #Webb 's unaligned mirror segments all reflecting light from the same star back at Webb's secondary mirror and into #NIRCam's detectors. Thread 👇 with a surprise at the end!
2/ The mosaic was created by pointing the telescope at a bright, isolated star in the constellation Ursa Major known as HD 84406, chosen specifically because it's easily identifiable and not crowded by other stars of similar brightness, which helps to reduce background confusion
3/ Each dot within the mosaic is labeled by the corresponding primary mirror segment that captured it. These initial results closely match expectations and simulations.
Tutto pronto per seguire il lancio del telescopio spaziale #Webb alle 13:20 ora italiana #Jwst
