Astronomers using NASA’s James Webb Space Telescope combined the capabilities of the telescope’s two cameras to create a never-before-seen view of a star-forming region in the Carina Nebula. Captured in infrared light by the Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI), this combined image reveals previously invisible areas of star birth. What looks much like craggy mountains on a moonlit evening is actually the edge of a nearby, young, star-forming region known as NGC 3324. Called the Cosmic Cliffs, this rim of a gigantic, gaseous cavity is roughly 7,600 light-years away. 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 center of the bubble, above the area shown in this image. The high-energy radiation from these stars is sculpting the nebula’s wall by slowly eroding it away. NIRCam – with its crisp resolution and unparalleled sensitivity – unveils hundreds of previously hidden stars, and even numerous background galaxies. In MIRI’s view, young stars and their dusty, planet-forming disks shine brightly in the mid-infrared, appearing pink and red. MIRI reveals structures that are embedded in the dust and uncovers the stellar sources of massive jets and outflows. With MIRI, the hydrocarbons and other chemical compounds on the surface of the ridges glow, giving the appearance of jagged rocks. Several prominent features in this image are described below. -- The faint “steam” that appears to rise from the celestial “mountains” is actually hot, ionized gas and hot dust streaming away from the nebula due to intense, ultraviolet radiation. -- Peaks and pillars rise above the glowing wall of gas, resisting the blistering ultraviolet radiation from the young stars. -- Bubbles and cavities are being blown by the intense radiation and stellar winds of newborn stars. -- Protostellar jets and outflows, which appear in gold, shoot from dust-enshrouded, nascent stars. MIRI uncovers the young, stellar sources producing these features. For example, a feature at left that looks like a comet with NIRCam is revealed with MIRI to be one cone of an outflow from a dust-enshrouded, newborn star. -- A “blow-out” erupts at the top-center of the ridge, spewing material into the interstellar medium. MIRI sees through the dust to unveil the star responsible for this phenomenon. -- An unusual “arch,” looking like a bent-over cylinder, appears in all wavelengths shown here. This period of very early star formation is difficult to capture because, for an individual star, it lasts only about 50,000 to 100,000 years – but Webb’s extreme sensitivity and exquisite spatial resolution have chronicled this rare event. NGC 3324 was first catalogued by James Dunlop in 1826. Visible from the Southern Hemisphere, it is located at the northwest corner of the Carina Nebula (NGC 3372), which resides in the constellation Carina. The Carina Nebula is home to the Keyhole Nebula and the active, unstable supergiant star called Eta Carinae.
