Link to The search for life, the Drake equation documentary
Documentary Description
For many years our place in the universe was the subject of theologians
and philosophers, not scientists, but in 1960 one man changed all that.
Dr Frank Drake was one of the leading lights in the new science of
radio astronomy when he did something that was not only revolutionary,
but could have cost him his career. Working at the National Radio
Astronomy Observatory in Greenback in Virginia, he pointed one of their
new 25-metre radio telescopes at a star called Tau Ceti twelve light
years from earth, hoping for signs of extra-terrestrial intelligence.
