Spectroscopy of Stars – Wonders of the Universe

Understand what the universe is made of by looking at the light of its stars. In this clip from Wonders of the Universe – Stardust, Professor Brian Cox demonstrates how chemical elements emit a unique set of colors when burned, and through the process of spectroscopy, how those unique colors can help us identify the chemical composition of distant stars.

In the archives: more from Brian Cox, more stars, and how we know details about distant exoplanets.
