UFO

Historical markers were once just for American history. But many now claim aliens have visited Earth from outer space — and they aren't hedging.

In the U.S. military's most comprehensive report addressing unconfirmed UFO sightings, defense officials concluded that most sightings dating back to 1945 were of ordinary origin.

NASA is releasing a new report from advisers on what it would take for the agency to study unidentified anomalous phenomena (also known as UFOs) scientifically.

It's not the first time Jaime Maussan has claimed to discover "nonhuman" bodily remains, and scientists have previously dismissed them.

NASA is trying to bring science to the study of unidentified anomalous phenomena. A panel of top scientists and academics is trying to figure out how to systematically study UAPs.

The All-Domain Anomaly Resolution Office, formed last year, is focusing on some 171 cases — including some in which objects "appear to have demonstrated unusual flight characteristics."

That's up from 143 incidents in a report issued in 2021. Officials partly credited reducing stigma around the issue for the new reports, many of which are older and went unmentioned at the time.

The hearing followed the release of an intelligence community report looking at 144 incidents of UAPs, unidentified aerial phenomena, since 2004.

Employing science's methodology is key — as it's the best antidote we have to the very human propensity to turn something we want to believe into a reality, says astrophysicist Marcelo Gleiser.

NPR's Lulu Garcia-Navarro talks to Politico's Bryan Bender, one of the reporters who publicly revealed the existence of the Pentagon program for the first time.
