'Astonishing': James Webb telescope spots the most chemically primitive galaxy in the ancient universe

'Astonishing': James Webb telescope spots the most chemically primitive galaxy in the ancient universe The James Webb telescope peered into an ancient spot of light, and found it to be the most metal-poor galaxy in the early universe. One of the greatest achievements of the James Webb Space Telescope is how it has allowed scientists to push the boundaries of astronomy by observing galaxies that existed during the early universe, less than 1 billion years after the Big Bang. This period,...
