The Pentagon’s report on UAPs (Unidentified Aerial Phenomena) said nothing about the possibility that some might be alien spacecraft. Nonetheless, the report has generated heightened interest in figuring out what these UAPs are, and that interest extends to some scientists. We talk to two researchers who want an open and strictly scientific investigation of these phenomena. What should they do and what do they expect to find? And finally, will the possibility of alien visitors ever be resolved? Guests:  Jacob Haqq-Misra – Senior Research Investigator at the Blue Marble Space Institute of Science Ravi Kopparapu – Planetary scientist, NASA Goddard Space Flight Center Big Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.
