Astronomers “Blown Away” by First Breathtaking Webb Space Telescope Images of Orion Nebula

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 emissions from ionized gas, molecular gas, hydrocarbons, 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) 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.

Orion Nebula: JWST versus Hubble Space Telescope (HST): The inner region of the Orion Nebula as seen by both the Hubble Space Telescope (left) and the James Webb Space Telescope (right). The HST image is dominated by emission from hot ionized gas, highlighting the side of the Orion Bar which is facing the Trapezium Cluster (off the top right of the image). The JWST image also shows the cooler molecular material that is slightly further away from the Trapezium Cluster (compare the location of the Orion Bar relative to the bright star θ2 Orionis A for example). Webb’s sensitive infrared vision can furthermore peer through thick dust layers and see fainter stars. This will allow scientists to study what is happening deep inside the nebula.
