The James Webb Space Telescope has set records for finding some of the most distant confirmed galaxies. It has detected galaxies seen as they were more than 13 billion years ago.
The Full Story
The James Webb Space Telescope, launched in 2021, has pushed the frontier for distant galaxy observations. Its infrared instruments can detect extremely faint, redshifted light from the early universe. Webb has identified galaxies seen more than 13 billion years in the past, when the universe was only a few hundred million years old. It has also revealed unexpectedly bright and mature-looking galaxies at very early times. These findings are reshaping ideas about how quickly galaxies formed after the Big Bang.
