Summary[edit]

Description
English: A side-by-side display of the same region of the Tarantula Nebula brings out the distinctions between Webb’s near-infrared (closer to visible red, left) and mid-infrared (further from visible red, right) images. Each portion of the electromagnetic spectrum reveals and conceals different features, making data in different wavelengths valuable to astronomers for understanding the physics taking place.The image captured by Webb’s Near-Infrared Camera (NIRCam, left) features bright, hot features, like the sparkling cluster of massive young stars, and the bright star to their upper left, featuring Webb’s distinctive diffraction spikes. Young, emerging stars shine blue, while scattered red points indicate stars that are still enshrouded in dust. Structure in the nebula, carved by the stellar winds of the massive young stars, is intricately detailed.In the view from Webb’s Mid-Infrared Instrument (MIRI), the hot young stars fade, and cooler gas takes the spotlight. Much of the nebula takes on a ghostly appearance in the mid-infrared, because these longer wavelengths of light are able to penetrate the dust clouds and reach Webb. Previously hidden bubbles and dust-embedded stars emerge. A particularly prominent, spherically shaped bubble – being blown out by a newborn star – appears in the MIRI image just to the right of the now-darkened central star cluster.Another difference between the two images is the appearance of the bright, lone star at the top of the nebula’s cavity. In the MIRI image (right) the star is fainter relative to the surrounding nebula, so the glare and the distortion of Webb’s diffraction spikes are much less prominent.In the midst of the central cluster of young stars, one dense gas clump is clearly visible in both images – it is one of the last, dense remnants of the nebula that the young cluster stars’ stellar winds have not yet eroded away.NIRCam was built by a team at the University of Arizona and Lockheed Martin’s Advanced Technology Center.MIRI was contributed by ESA and NASA, with the instrument designed and built by a consortium of nationally funded European Institutes (The MIRI European Consortium) in partnership with JPL and the University of Arizona.
