James Webb Space Telescope discovers 138 asteroids, including 6 on Earth-bound paths. Small, decameter-sized threats highlight the urgent need for planetary defense.

Nicknamed the Firefly Sparkle, this galaxy existed just 600 million years after the Big Bang and gleams with 10 distinct star clusters.

A team of astronomers just spotted dozens of tiny asteroids in JWST date — including the smallest ever seen in the main belt between Mars and Jupiter.

The James Webb telescope spent another year collecting instantly iconic space imagery. Here are some of our favorites.
