The James Webb Space Telescope (JWST) is the largest and most powerful space telescope that humanity has ever created, enabling scientists to gaze further into the universe than ever before.
But more impressively, thanks to the (relatively) limited speed of light, the JWST can effectively peer back in time to the early universe — over 13.5 billion years ago — to study how the first galaxies were born after the Big Bang. Since it launched back in 2021, we've already made some staggering discoveries about the cosmos.
