About This Video

In a flash known as the Big Bang, our universe was born. Yet for hundreds of thousands of years, light from the Big Bang was scattered and trapped in a dense fog. Eventually, though, that light made its “great escape” and the universe was plunged into total darkness. These cosmic “Dark Ages” lasted for millions of years until the first stars and galaxies burst to life and began to illuminate the universe. However, no one knows just when this happened or what the earliest stars and galaxies were really like, because we’ve never seen them.

NASA’s Webb telescope, currently under construction and due to launch in 2021, will use its powerful infrared vision to spy the very first stars and galaxies forming out of the darkness of the early universe and help us understand how today’s universe came to be.
