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 👇
@HUBBLE_space #NIRCam, Webb’s primary imager, has revealed more stars than observed with visible light. This is because young stars are less obscured by dust when viewed in the infrared. In this image #NIRCam data are blue, orange and yellow 👇
@HUBBLE_space The fine details in the galaxy require Webb’s #MIRI instrument, coloured red in the image. MIRI reveals regions in the Cartwheel's dust rich in hydrocarbons, chemical compounds and silicate dust. These regions, resembling spiralling spokes, form the galaxy’s skeleton 👇
@HUBBLE_space Webb’s powerful infrared instruments have produced this detailed image of the current state of the Cartwheel, but it also provides insight into the Cartwheel’s past and how it will evolve in future. Read more at esawebb.org/news/weic2211/

What you see here is a transmission spectrum made from a single observation using Webb’s NIRISS instrument. Let's take a closer look at it 👇
A transmission spectrum is made by comparing starlight filtered through a planet’s atmosphere as it moves across the star, to the unfiltered starlight detected when the planet is beside the star 👇
🔴 Each of the 141 data points (white circles) on this graph represents the amount of a specific wavelength of light that is blocked by the planet and absorbed by its atmosphere 👇

📢 #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👇 Image
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 👇 Image
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 reveals never-before-seen details of galaxy group “Stephan’s Quintet”, giving astronomers a ringside seat to galactic mergers and interactions. Read more here: esawebb.org/news/weic2208/ or below 👇
Stephan’s Quintet is a visual grouping of 5 galaxies with only 4 of the galaxies truly close together & caught up in a cosmic dance — a fantastic “laboratory” for scientists to see in detail how interacting galaxies trigger star formation & how gas is being disturbed 👇
Tight groups like this may have been more common in the early universe when their infalling material may have fuelled very energetic black holes. Even today, the topmost galaxy harbours an active galactic nucleus, a supermassive black hole 24 million times the mass of the Sun 👇

📢#Webb reveals details of the Southern Ring planetary nebula that were previously hidden, helping us better understand how stars evolve and transform their environments. Read more here: esawebb.org/news/weic2207/ or below 👇#WebbSeesFarther
Some stars save the best for last 💥 Planetary nebulae are the shells of gas and dust ejected from dying stars — making for a spectacular view. Since they exist for tens of thousands of years, observing such a nebula is like watching a movie in exceptionally slow motion 👇
Two stars, which are locked together in a tight orbit, shape the local landscape of this planetary nebula. Webb's infrared images feature new details in this complex system 👇

📢 #Webb reveals steamy atmosphere ♨️ of exoplanet WASP-96 b, capturing the distinct signature of water 💧 along with evidence for clouds & haze — the most detailed measurements of this kind to date. Read more here: esawebb.org/news/weic2206/ or below 👇 #WebbSeesFarther
WASP-96 b is a hot, puffy gas giant planet orbiting a distant Sun-like star. On 21 June, Webb’s #NIRISS measured light from the WASP-96 system for 6.4 hours as the planet moved across the star 👇
The result: a light curve— showing the overall starlight dimming during transit, when the planet blocks some starlight, and a transmission spectrum— made by comparing starlight filtered through a planet’s atmosphere to unfiltered starlight when the planet is beside the star 👇

📢 #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 👇
