Studies have established that the majority of UFO observations are misidentified conventional objects or natural phenomena—most commonly aircraft, balloons, noctilucent clouds, nacreous clouds, or astronomical objects such as meteors or bright planets with a small percentage even being hoaxes. After excluding incorrect reports, however, most investigators have acknowledged that between 5% and 20% of reported sightings remain unexplained, and therefore can be classified as unidentified in the strictest sense. Many reports have been made by such trained observers as pilots, police, and the military; some have involved simultaneous radar tracking and visual accounts. Proponents of the extraterrestrial hypothesis suggest that these unexplained reports are of alien spacecraft, though various other hypotheses have been proposed.
While UFOs have been the subject of extensive investigation by various governments and although some scientists support the extraterrestrial hypothesis, few scientific papers about UFOs have been published in peer-reviewed journals. There has been some debate in the scientific community about whether any scientific investigation into UFO sightings is warranted.
The void left by the lack of institutional scientific study has given rise to independent researchers and groups, including NICAP (the National Investigations Committee on Aerial Phenomena) in the mid-20th century and, more recently, MUFON (Mutual UFO Network) and CUFOS (Center for UFO Studies). The term "Ufology" is used to describe the collective efforts of those who study reports and associated evidence of unidentified flying objects. According to MUFON, as of 2011 the number of UFO reports to their worldwide offices has increased by 67% from the previous three years and now averages around 500 reported sightings per month.
UFOs have become a relevant theme in modern culture, and the social phenomena have been the subject of academic research in sociology and psychology.

Famous quotes containing the word studies:
“His life itself passes deeper in nature than the studies of the naturalist penetrate; himself a subject for the naturalist. The latter raises the moss and bark gently with his knife in search of insects; the former lays open logs to their core with his axe, and moss and bark fly far and wide. He gets his living by barking trees. Such a man has some right to fish, and I love to see nature carried out in him.”
—Henry David Thoreau (18171862)
“These studies which stimulate the young, divert the old, are an ornament in prosperity and a refuge and comfort in adversity; they delight us at home, are no impediment in public life, keep us company at night, in our travels, and whenever we retire to the country.”
—Marcus Tullius Cicero (10643 B.C.)
“[B]y going to the College [William and Mary] I shall get a more universal Acquaintance, which may hereafter be serviceable to me; and I suppose I can pursue my Studies in the Greek and Latin as well there as here, and likewise learn something of the Mathematics.”
—Thomas Jefferson (17431826)
