How James Webb will reveal what Hubble missed - Hubble's deepest views of space revealed fewer than 10% of the Universe's galaxies. James Webb will change that forever.

The James Webb Space Telescope has been designed to answer many of the core questions that have animated astronomers over the past half-century. With a $10 billion price tag, it is one of the most ambitious engineering initiatives ever attempted. But for it to achieve its potential — nothing less than to rewrite the history of the cosmos and reshape humanity’s position within it — a lot of things have to work just right.
