For four years the Kepler space telescope stared at roughly 150,000 stars in a single patch of sky about 3,000 light years from Earth, watching for the tiny dimming that happens when a planet crosses in front of its star. This film uses that data to ask whether Earth is one of many life-bearing worlds or a rare exception, tracing the question back through Copernicus, who put the Sun at the center of the solar system, and Giordano Bruno, the Italian monk burned in 1600 for arguing the universe held countless inhabited worlds. Galileo's telescope later confirmed the basic premise by showing the Sun is just one star among many. The film sets the Kepler results against that long history of speculation, from ancient Chinese, Indian, Greek, and Egyptian cosmologies to religious texts that imagined a crowded cosmos, and treats the mission's planet counts as the first real evidence bearing on an argument that is thousands of years old.
