NASA panel studying UFO sightings says stigma and poor data pose challenges

A NASA panel tasked with studying reports of "unidentified aerial phenomena" said at a hearing that the stigma associated with reporting UFO sightings — as well as the harassment of people who work to investigate them — may be hindering efforts to determine their origins.

The panel, which was formed last year, presented early findings Wednesday in the group’s first public meeting and is expected to publish a final report this summer. The team highlighted the need for more high-quality data to properly investigate unusual sightings.

Daniel Evans, the assistant deputy associate administrator for research in NASA’s Science Mission Directorate, said there has been no convincing evidence that reports of UFOs have anything to do with aliens. While extraterrestrial origins are not being ruled out, the independent group was convened to address broader national security concerns, he said.（本段为发音精讲部分，具体语音讲解请微信关注【可可英语晨读公众号】）

"There could potentially be very serious risks to U.S. airspace as a result of us not necessarily knowing what is in our skies at a given time," Evans said Wednesday in a news briefing.

Debates over potential UFO sightings have garnered increased attention in recent years, particularly as Congress and U.S. intelligence agencies have sought to make public more information about unidentified flying objects and data from reported incidents.
