NASA’s Webb Space Telescope is finding bright, early galaxies that until now were hidden from view, including one that may have formed a mere 350 million years after the cosmic-creating Big Bang.
This image made available by the Space Telescope Science Institute on Thursday, Nov. 17, 2022, shows two of the farthest galaxies seen to date captured by the James Webb Space Telescope in the outer regions of the giant galaxy cluster Abell 2744. The galaxies are not inside the cluster, but many billions of light-years farther behind it. The galaxy labeled"1" existed only 450 million years after the big bang. The galaxy labeled"2" existed 350 million years after the big bang.
Naidu said more observations are needed in the infrared by Webb before claiming a new distance record-holder. Tommaso Treu of the University of California, Los Angeles, a chief scientist for Webb's early release science program, said the evidence presented so far “is as solid as it gets” for the galaxy believed to have formed 350 million after the Big Bang.
NASA's Jane Rigby, a project scientist with Webb, noted that these galaxies “were hiding just under the limits of what Hubble could do.”
