NASA doesn’t know what UFOs are—but it knows most of them aren't aliens.

As for the rest of the unidentified anomalous phenomena (UAP)… who knows? “There’s missing data,” David Spergel, the chair of a new NASA study into UAPs, told reporters Thursday.

Gathering that data is the space agency’s first task as it moves to make UAP research a top priority alongside space exploration, aeronautics, and Earth science, Spergel and other top NASA officials said when they rolled out the UAP report Thursday morning.

The trick is gathering data that’s scientifically useful. That means fewer frantic emails from someone claiming their late uncle once saw something weird—an example Spergel cited from his own inbox—and more formal reports from astronomers and pilots, and even everyday people using apps that embed high-quality metadata in photos and videos of strange objects flitting around the sky.
