Just one week after the JWST revealed its first images, a team has used the telescope’s data to find a candidate for the earliest galaxy ever seen, one that existed 13.5 billion years ago.
including the deepest infrared image of the universe , a team has used the telescope’s data to find a candidate for the earliest galaxy ever seen, one that existed 13.5 billion years ago. If correct, the galaxy was shining just 300 million years after the big bang. The previous record was held by a galaxy called GN-z11, seen by the Hubble Space Telescope when the universe was 400 million years old.
As, one of Webb’s “early release science” projects has scanned images from Webb’s near-infrared camera and found signs of two very distant galaxies, one at a similar distance to GN-z11 and another even farther, dubbed GLASS-z13. The distances were obtained using a relatively crude method involving their brightness at different wavelength bands.
