Stories of UFOs, or unidentified flying objects, are as much a part of humanity’s story as the fairy tales of yesteryear. Strange images in the skies have been noted throughout history, particularly after World War II with the rise of rocketry and the Cold War. Historians note that the first, best-known UFO sighting occurred in 1947, when small-time aviator Kenneth Arnold claimed to see “a group of nine, high-speed objects near Mount Rainier in Washington” in flight. As the number of sightings increased to a record number in the 1950s and 1960s, the U.S. Air Force opened several investigations into UFOs, which were declassified in 1979.
We can only imagine what strange images NASA may have picked up since then. Here are seven interesting UFO-like images from NASA and other sources, most of which have been debunked with detailed explanations. But the real question is, do you believe in them? (Text: Katherine Butler)
