James Webb Space Telescope uncovers new details in Pandora'sCluster NASA
The combined mass of the galaxy clusters creates a powerful gravitational lens, a natural magnification effect of gravity, allowing much more distant galaxies in theOnly Pandora's central core has previously been studied in detail by the NASA/ESA Hubble Space Telescope.
Astronomers studied the region as part of the Ultradeep NIRSpec and NIRCam ObserVations before the Epoch of Reionization program. The new view of Pandora's Cluster stitches four Webb snapshots together into one panoramic image, displaying roughly 50 000 sources of near-infrared light.distorts the appearance of distant galaxies, so they look very different from those in the foreground.
Astronomers estimate 50,000 sources of near-infrared light are represented in this image from the NASA/ESA/CSA James Webb Space Telescope. Their light has traveled through various distances to reach the telescope's detectors, representing the vastness of space in a single image. A foreground star in our own galaxy, to the right of the image center, displays Webb's distinctive diffraction spikes.
In the lensing core to the lower right in the Webb image, which has never been imaged by Hubble, Webb revealed hundreds of distant lensed galaxies that appear like faint arced lines in the image. The UNCOVER team used Webb's Near-Infrared Camera to capture the cluster with exposures lasting 4–6 hours, for a total of about 30 hours of observing time. The next step is to meticulously go through the
