12 James Webb Space Telescope findings that changed our understanding of the universe in 2023

On Christmas morning two years ago, astronomers and space fans received the gift they’d been waiting for 30 years: the launch of the James Webb Space Telescope (JWST), the world’s biggest, most daring endeavor to probe the earliest stars and galaxies in the universe. 

This year, the space observatory has continued to deliver breathtaking and scientifically valuable images of the cosmos. Here’s a look back at the JWST discoveries that altered our understanding of the universe in 2023.
