spiral galaxies and distant galaxies are visible against the black void of space A small portion of deep space observed by JWST. NASA/STScI/CEERS/TACC/S. Finkelstein/M. Bagley/Z. Levay Astronomers armed with early data obtained by the James Webb Space Telescope (JWST) are hunting galaxies that existed just a few hundred million years after the Big Bang. Rohan Naidu, an astrophysicist based at Harvard's and Smithsonian's jointly operated Center for Astrophysics, and his colleagues have been particularly good at uncovering these cosmic relics. Just a few days after the JWST's first images were beamed across the planet in July, Naidu and his collaborators...

The GLASS-z13 galaxy imaged by JWST. (NASA, ESA, CSA, and STScI/AFP) Just a week after its first images were shown to the world, the James Webb Space Telescope may have found a galaxy that existed 13.5 billion years ago, a scientist who analyzed the data said Wednesday. Known as GLASS-z13, the galaxy dates back to 300 million years after the Big Bang, about 100 million years earlier than anything previously identified, Rohan Naidu of the Harvard Center for Astrophysics told AFP. "We're potentially looking at the most distant starlight that anyone has ever seen," he said. The more distant objects...
