NASA's James Webb Telescope exceeds expectations again, snaps Pandora cluster in fine detail

NASA's James Webb Space Telescope has shared another surprising view of a celestial object. The James Webb Telescope has captured the region in space identified as Pandora's Cluster (Abell 2744), which reveals three already enormous clusters of galaxies converging to create a mega-cluster. This combined mass generates a potent gravitational lens, a natural effect of gravity that amplifies the observation of galaxies in the early universe located far beyond the cluster by utilizing it like a magnifying glass.

Earlier, NASA's Hubble Space Telescope had captured only the central core of Pandora. Thanks to the great and powerful infrared instruments combined with a broad mosaic view of the region's multiple areas of lensing of the Webb telescope, astronomers could achieve a balance of breadth and depth to study cosmology and galaxy evolution.

“When the images of Pandora's Cluster first came in from Webb, we were honestly a little star struck. There was so much detail in the foreground cluster and so many distant lensed galaxies, I found myself getting lost in the image. Webb exceeded our expectations,” a NASA blog quoted astronomer Rachel Bezanson of the University of Pittsburgh in Pennsylvania.

Webb's new view of Pandora's Cluster stitches 4 snapshots together into a panorama, showing 3 separate galaxy clusters merging into a mega-cluster and some 50,000 sources of near-infrared.

Researchers utilized Webb's Near-Infrared Camera (NIRCam) to capture the cluster by taking exposures lasting between 4 to 6 hours, resulting in an overall observing time of approximately 30 hours. After that, the team analyzes the imaging data to select specific galaxies for further observation with the Near-Infrared Spectrograph (NIRSpec), allowing
