The James Webb Space Telescope\u2019s first image of Carina Nebula shows an iconic star-forming cloud of gas and dust 7,600 light-years away, revealing previously unseen vistas of young stars thanks to the new observatory\u2019s sharp-eyed infrared vision.<\/p>\n

This is one of the first batch of images from Webb revealed Tuesday by the science team working on the $10 billion mission.<\/p>\n

\u201cThe stunning vista of the cosmic cliffs of the Carina Nebula reveals new details about this vast stellar nursery,\u201d said Amber Straughn, Webb\u2019s deputy project scientist at NASA\u2019s Goddard Space Flight Center. \u201cToday, for the first time, we\u2019re seeing brand new stars that were previously completely hidden from our view.\u201d<\/p>\n

The tallest of the \u201cmountains\u201d of gas and dust visible in this image are 7 light-years high, according to NASA. The star-forming region of Carina Nebula imaged by Webb is known as NGC 3324.<\/p>\n

\u201cWhen I see an image like this, I can\u2019t help but think of scale,\u201d Straughn said. \u201cEvery dot of light we see here is an individual star not unlike our sun, and many of these likely also have planets. It just reminds me that our sun and our planets, and ultimately us, were formed out of the same kind of stuff that we see here.\u201d<\/p>\n

Webb\u2019s Near Infrared Camera (NIRCam) and Mid Infrared Instrument (MIRI) combined to observe Carina Nebula and the NGC 3324 cloud. See the full-resolution (124.7 MB) view of Carina Nebula.<\/p>\n

The gas and dust in the bottom half of the picture is being shaped and twisted by gigantic, young stars expelling radiation and stellar winds in a pocket near the top of the image.<\/p>\n

\u201cDramatic pillars tower above the glowing wall of gas, resisting this radiation,\u201d NASA said in a press release. \u201cThe \u2018steam\u2019 that appears to rise from the celestial \u2018mountains\u2019 is actually hot, ionized gas and hot dust streaming away from the nebula due to the relentless radiation.\u201d<\/p>\n

\u201cIn this view, we see some great examples of hundreds of new stars that we\u2019ve never seen before,\u201d Straughn said. \u201cWe see examples of bubbles and cavities and jets that are being blown out by these newborn stars. We even see some galaxies lurking in the background.\u201d<\/p>\n

Carina Nebula was previously imaged by the Hubble Space Telescope. Hubble\u2019s instruments are tuned to observe the universe in ultraviolet, visible, and near-infrared light, and the telescope\u2019s primary mirror is about a third the size of Webb, which is sensitive to longer wavelengths of infrared light.<\/p>\n

\u201cYou can see amazing things with Hubble,\u201d Straughn said. \u201cWhen we zoom in to this new image, we\u2019re able to see so much more detail \u2026 You sort of get this sense of depth and texture with this new data.\u201d<\/p>\n

Webb\u2019s sensitivity to thermal energy allows it to see through gas and dust clouds that obscure telescopes observing in visible light. The youngest stars in Webb\u2019s view of Carina Nebula appear as red dots in the dark, dusty region of the cloud.<\/p>\n

\u201cObjects in the earliest, rapid phases of star formation are difficult to capture, but Webb\u2019s extreme sensitivity, spatial resolution, and imaging capability can chronicle these elusive events,\u201d NASA said.<\/p>\n

Stars form as gas and dust material inside clouds like the one viewed by Webb. Pressure from the stellar winds of nearby stars can help trigger this type of event.<\/p>\n

\u201cConversely, this type of disturbance may also prevent star formation as the star-making material is eroded away,\u201d NASA said. \u201cThis is a very delicate balance between sparking star formation and stopping it. Webb will address some of the great, open questions of modern astrophysics: What determines the number of stars that form in a certain region? Why do stars form with a certain mass?\u201d<\/p>\n
