Season 52 Episode 1 | 5m 00s

There have been reports of UFO and UAP sightings for decades, but these accounts are often difficult to verify. Now, scientists are in search of the elusive: hard data. From machine learning sites that analyze the sky 24/7, to a crowd-sourcing app that asks the public to submit their own UFO videos, discover the inventive methods at play to capture more data.
