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…
2/ Webb is renowned for its mid-infrared capabilities provided by #MIRI. Mid-infrared light, with wavelengths between 3 & 30 micrometres, allows us to see the Universe in a specific way, with objects that appear dark at visible wavelengths shining brightly in the mid-infrared.
3/ “It's such an exciting wavelength range in terms of the chemistry that you can do, and the way you can understand star formation and what's happening in the nuclei of galaxies,” says Gillian Wright, the Principal Investigator for the European Consortium behind #MIRI
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 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 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/ The Mid-InfraRed Instrument #MIRI is one of 4 instruments on the James #Webb Space Telescope. The only mid-infrared instrument in its instrument suite. #WebbSeesFarther

2/ Thanks to state-of-the-art instrument design and components, it will deliver mid-infrared images and spectra with an unprecedented combination of sharpness and sensitivity. #WebbSeesFarther
Tutto pronto per seguire il lancio del telescopio spaziale #Webb alle 13:20 ora italiana #Jwst

Our new homepage is now online -- check it out at metis.strw.leidenuniv.nl and don't miss our "METIS app" metis-app.strw.leidenuniv.nl that lets you see how METIS will operate! @ASTRON_NL @ukatc @mpi_astro @univienna @CEAParisSaclay @ETH_physics @IvS_KULeuven @UniCologne
@ASTRON_NL @ukatc @mpi_astro @univienna @CEAParisSaclay @ETH_physics @IvS_KULeuven @UniCologne Our explainer app metis-app.strw.leidenuniv.nl starts off with a screen showing the optical layout of METIS and its various subsystems.
METIS offers five main observing modes (direct imaging, high contrast imaging, long-slit spectroscopy, IFU spectroscopy and IFU spectroscopy combined with high contrast imaging). In each mode, various sub-modes are available.
