A month ago, space enthusiasts around the world were treated to the first spectacular views of our universe captured by the James Webb Space Telescope (JSWT), the most powerful observatory ever launched. 

Since then, the JWST team has released incredible images of dying stars, cartwheeling galaxies, and the ancient universe. Astronomers, who have been waiting for this data for decades, have published a flurry of new research based on the unprecedented observations, including potential discoveries of galaxies that are farther back in time and space than ever seen before.
