The inner region of the Orion Nebula as seen by the NIRCam instrument on board the NASA/ESA/CSA James Webb Space Telescope. This is a composite image from several filters that represents emission from ionized gas, hydrocarbons, molecular gas, dust and scattered starlight. Most prominent is the Orion Bar, a wall of dense gas and dust that runs from the top left to the bottom right in this image, and that contains the bright star θ2 Orionis A. The scene is illuminated by a group of hot, young massive stars -- known as the Trapezium Cluster -- that is located just off the top right of the image. The strong and harsh ultraviolet radiation of the Trapezium cluster creates a hot, ionized environment in the upper right, and slowly erodes the Orion Bar away. Molecules and dust can survive longer in the shielded environment offered by the dense Bar, but the surge of stellar energy sculpts a region that displays an incredible richness of filaments, globules, young stars with disks and cavities.

The unusual shape of the open cluster NGC 346 is partly due to stars and gas spiraling into the center of the cluster in a river-like motion; the red spiral superimposed on NGC 346 traces the movement of stars and gas toward the center; this spiraling motion is the most efficient way to feed star formation from the outside toward the center of the cluster.

Messier 74, a grand design spiral galaxy located 32 million light-years away in the constellation of Pisces, shines at its brightest in this combined optical/mid-infrared image, featuring Webb and Hubble data. The red colors mark dust threaded through the arms of the galaxy, lighter oranges being areas of hotter dust. The young stars throughout the arms and the nuclear core are picked out in blue. Heavier, older stars towards the galaxy’s center are shown in cyan and green, projecting a spooky glow from the core of Messier 74. Bubbles of star formation are also visible in pink across the arms.

This landscape of ‘mountains’ and ‘valleys’ speckled with glittering stars is actually the edge of the Carina Nebula, a huge star-forming region some 7,500 light-years away in the constellation of Carina. Captured in infrared light by Webb, this image reveals for the first time previously invisible areas of star birth. 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 the Carina Nebula, and the tallest ‘peaks’ in this image are about 7 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 center of the bubble, above the area shown in this image.

This composite image shows the Tarantula Nebula. The background image, taken in the infrared, is itself a composite: it was captured by the HAWK-I instrument on ESO’s Very Large Telescope (VLT) and the Visible and Infrared Survey Telescope for Astronomy (VISTA), shows bright stars and light, pinkish clouds of hot gas. The bright red-yellow streaks that have been superimposed on the image come from radio observations taken by the ALMA, revealing regions of cold, dense gas which have the potential to collapse and form stars. The unique web-like structure of the gas clouds led astronomers to the nebula’s spidery nickname. Image credit: ESO / ALMA / NAOJ / NRAO / Wong et al. / M.-R. Cioni / VISTA Magellanic Cloud Survey / Cambridge Astronomical Survey Unit.
