The Pentagon declassified a series of videos that show UAP -- unexplained aerial phenomena. That does not mean the videos show evidence of alien aircraft; in fact, such videos tend to be debunked with a little bit of analysis.

- Adam Frank, astrophysicist at the University of Rochester, and author of "Light of the Stars"
- Jacob Haqq Misra, senior research investigator at Blue Marble Space Institute of Science
- Ravi Kumar Kopparapu, planetary scientist at NASA Goddard Space Flight Center
