The inner region of the Orion Nebula as seen by the James Webb Space Telescope’s NIRCam instrument.
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 θ
2 Orionis A. The scene is illuminated by a group of hot, young massive stars (known as the Trapezium Cluster) which 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.

Technical details: The image was obtained with the James Webb Space Telescope NIRCam instrument on September 11, 2022. Several images in different filters were combined to create this composite image: F140M and F210M (blue); F277W, F300M, F323N, F335M, and F332W (green); F405N (orange); and F444W, F480M, and F470N (red).
