Thousands of planets now confirmed beyond our solar system, most of them found by a single instrument: the Kepler space telescope, which watched stars for the faint, repeating dimming that means something is passing in front of them, the transit method. This film follows that detection work and what it has turned up so far, from gas giants hugging their stars to smaller, rockier candidates that might sit in a habitable zone. It lays out why the easy targets get found first and why an Earth-sized planet is much harder to catch, since the dip in starlight it causes is tiny and easy to miss with current instruments. Researchers explain how each new exoplanet gets sized up for temperature, orbit, and composition before anyone can even guess at habitability, let alone life. The film stays with the tools and their limits rather than speculation, framing the search less as a moment of discovery and more as a slow, ongoing survey of a galaxy that appears to be full of planets.
