UFO is an unusual apparent
anomaly in the sky that is not readily identifiable to the observer as any
known object, often associated with extraterrestrial
life. The first reports of sightings typically
referred to mystery airships. In June 1947, Kenneth Arnold gave rise to the popular terms "flying saucer" and "flying disc," that most of
the objects he saw were not exactly circular and that one was crescent-shaped.
While technically an UFO refers to any unidentified flying object, in modern popular
culture the term UFO has generally become synonymous with alien spacecraft; however, the term ETV (ExtraTerrestrial Vehicle) is sometimes used
to separate this explanation of UFOs from totally earthbound explanations. Ruppelt felt that "flying saucer" did
not reflect the diversity of the sightings. He suggested that UFO should be
pronounced as a word you-foe. However it is now usually pronounced by
forming each letter: U.F.O. Because the term is ambiguous, referring
either to any unidentified sighting or in popular usage to alien spacecraft.
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. 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.
Unexplained aerial observations have been reported throughout history.
Some were undoubtedly astronomical in nature: comets, bright meteors, one or more of the five planets that can be seen with the naked
eye, planetary conjunctions, or atmospheric optical phenomena such as parhelia and lenticular clouds. An example is Halley's Comet.
Ufology is a neologism describing the collective efforts of those who
study UFO reports and associated evidence.
Some ufologists recommend that observations be classified
according to the features of the phenomenon or object that are reported or recorded.
Typical categories include:
·
Cigar-shaped "craft" with lighted windows (Meteor
fireballs are sometimes reported this way, but are very different phenomena).
·
Other: chevrons, (equilateral) triangles, crescent, boomerangs,
spheres (usually reported to be shining, glowing at night), domes, diamonds,
shapeless black masses, eggs, pyramids and cylinders, classic
"lights".
Unidentified flying objects and aliens can be proven
through eyewitness accounts or encounters. One of the most common cases would
be the case of the Hill’s. This proves that UFO’s and aliens are real because
when explaining what had happen they were both in separate rooms under
hypnotist ion. And also there was no one to explain the lost in the time or the
marks on the body and the car. UFO enthusiasts persist, however, and
some people even claim to have been abducted and taken aboard UFOs. No one has
produced scientifically acceptable proof of these claims.
