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.
