Watch BBC: The Planets – 08 – Destiny (1999) Documentary Online


The Planets – Destiny. All stars have a finite amount of fuel to burn before they expand into red giants and then collapse into darkness.

In three billion years, the sun will expand into a red giant and may consume Earth. Scientists are already searching for a planet in nearby solar systems with Earthlike qualities that humans can one day inhabit. They have found nearly 150 planets around other stars, in other solar systems, but none resemble Earth. In the next two decades, more missions will launch to look for Earthlike planets, take their pictures, analyze their atmospheres and answer the questions, Are there other inhabitable planets?

Are we alone in the universe? Or is there life everywhere?
