James Webb: Seeing the First Galaxies

Editor's Take

Marking the James Webb Space Telescope's first year of science, this film considers what it means to capture light from galaxies formed only a few hundred million years after the Big Bang. It explains how the instrument sees further into space and time than any before it, and why those earliest galaxies matter to accounts of cosmic origins. The approach is expository, translating a technical achievement into its larger significance. It is a lucid briefing on a genuinely new window on the universe.

This documentary celebrates the James Webb Space Telescope's first year of science, when it captured light from galaxies that formed only a few hundred million years after the Big Bang. It explains how the telescope peers deeper into space and time than anything before it, and what those earliest galaxies reveal about the origins of the cosmos. Scientists reflect on discoveries that are already rewriting the textbooks. Awe-inspiring and clear, it makes cutting-edge astronomy easy to follow. Free to watch in HD on Dr Documentary.
