Nelson's comment has to think of findings in the new Pentagon's new report, which is expected to be announced later this month.

We don't know if they are from outside the earth or not, if it is an enemy or optical phenomenon, Nelson said.

NASA press secretary Jackie McGuinness said Nelson did not establish a full-time group to start investigating UFOs.

Do not really have many data and scientists should be free to monitor these clues without stigma, McGuinness said, acknowledges that UFO research may be considered negative and associated with negative theory

Nelson said NASA did not work directly with the Pentagon on the above report, but he added that if NASA scientists achieved progress in identifying objects, the Pentagon will know.

During the press conference on June 2, Astronomical Physics Thomas Zurbuchen, NASA's Deputy Director of Science, expressed that he did not believe UFOs as evidence of an alien technology civilization.

People tend to underestimate nature.
