The United States space agency says the study of UFOs will require a science-based approach and new techniques as NASA appointed a director to lead research on objects that the US government calls unidentified anomalous phenomena (UAP).

The agency has found no evidence that UAP have extraterrestrial origins, NASA Administrator Bill Nelson said on Thursday after it released a years-long study.
