Which space telescope has observed the earliest light from the universe most effectively?
Quick Answer
The James Webb Space Telescope is currently the most powerful observatory for studying the early universe in infrared. It has revealed galaxies from only a few hundred million years after the Big Bang.
The Full Story
The James Webb Space Telescope is the most effective instrument yet for exploring the early universe in infrared light. Because the expansion of the universe stretches ancient light into infrared wavelengths, JWST can detect galaxies formed only a few hundred million years after the Big Bang. It has produced some of the deepest and most distant galaxy images ever taken. Its observations are reshaping astronomers’ understanding of how quickly galaxies, stars, and black holes formed.
