2022 has certainly been a busy year for space news but it wasn’t all looking at what’s happening out there. Some of the news and research was about what’s happening on our own planet. Earlier this year, Congress held a public hearing on a topic that hasn’t been discussed openly in a congressional hearing in decades: unidentified flying objects. Yes, UFOs, or as the Pentagon is calling them, unidentified aerial phenomena, or UAPs. The hearing follows a report from the director of national intelligence released in June of 2021 that said there were over 140 recorded sightings of UAPs. Chris Impey, a professor of astronomy at the University of Arizona, has been following these developments. Below is an edited transcript of his conversation with Marketplace’s Kimberly Adams about the hearing.
