00:00NASA's James Webb Space Telescope presents a new view of Abel 2744,
00:06also known as Pandora's Cluster, displaying various depths of space in a single image,
00:11ranging from a foreground star in our own galaxy,
00:14to the megacluster forming as multiple massive galaxy clusters merge 4 billion light-years away,
00:21to the even more distant galaxies behind the cluster,
00:24whose light is magnified and distorted by the megacluster's warping of spacetime.
00:30Without the cluster's magnification boost,
00:33even the Webb Telescope could not see these faint, extremely distant galaxies.
00:40Some features that Webb shows distinctly, like this dusty red galaxy,
00:45were not detected at all when the Hubble Space Telescope studied the region.
00:49Astronomers are using this image to choose certain galaxies for follow-up
00:53to get precise distance measurements and details about intriguing features.
01:00This small red dot is a distant source of infrared light that has so far defied characterization.
01:08It must be extremely compact, because even with the visual stretching caused by the cluster's
01:13warped spacetime, it still appears as a tiny dot. One theory is that it is a glowing disk of gas
01:20surrounding a supermassive black hole in the early universe. Webb's follow-up observations will further
01:26reveal the wonders of Pandora's cluster and uncover a new understanding of the universe.
