The James Webb Space Telescope reveals the earliest stages of galaxy formation in a time when the universe was less than 1 billion years old.
The James Webb Space Telescope is NASA's largest and most powerful space observatory. The $10 billion space telescope will be the successor to the iconic Hubble Space Telescope. Webb will study several areas of astronomy and cosmology, gazing deep into the cosmos to study how the universe formed. Read the latest news about NASA's James Webb Space Telescope here.
