The Pentagon has started releasing files related to unidentified anomalous phenomena, or UFOs. Here are the images released so far

By Jeanna Bryner edited by Claire Cameron

The Pentagon on Friday released what appears to be the first batch of government files related to UFOs, or unidentified anomalous phenomena (UAPs). The files include Federal Bureau of Investigations reports into unexplained sightings as well as NASA debriefs with astronauts who saw things on the moon they couldn't identify—some of which was captured in images.

Scientific American's Adam Kovac reports that experts in the field are not surprised by any of the released files and say rather than quelling speculation the declassification could fuel it.

Here are some of the images included in the file release, as well as the information the Pentagon has provided saying what the photographs might show.
