The Bridgewater Triangle is an area of about 200 square miles (520 km2) within southeastern Massachusetts in the United States, claimed to be a site of alleged paranormal phenomena, ranging from UFOs to poltergeists, orbs, balls of fire and other spectral phenomena, various bigfoot-like sightings, giant snakes and "thunderbirds."

Fallstreak holeW
Fallstreak hole

A fallstreak hole is a large gap, usually circular or elliptical, that can appear in cirrocumulus or altocumulus clouds. Such holes are formed when the water temperature in the clouds is below freezing, but the water, in a supercooled state, has not frozen yet due to the lack of ice nucleation. When ice crystals do form, a domino effect is set off due to the Bergeron process, causing the water droplets around the crystals to evaporate: this leaves a large, often circular, hole in the cloud.

Flying saucerW
Flying saucer

A flying saucer is a descriptive term for a supposed type of flying craft having a disc or saucer-shaped body, commonly used generically to refer to an anomalous flying object. The term was coined in 1947 but has generally been supplanted since 1952 by the United States Air Force term unidentified flying objects. Early reported sightings of unknown "flying saucers" usually described them as silver or metallic, sometimes reported as covered with navigation lights or surrounded with a glowing light, hovering or moving rapidly, either alone or in tight formations with other similar craft, and exhibiting high maneuverability.

UFO conspiracy theoryW
UFO conspiracy theory

UFO conspiracy theories argue that various governments, and politicians globally, most especially the officials of Washington, D.C., are suppressing evidence of extraterrestrial unidentified flying objects and alien visitors. Such conspiracy theories commonly argue that Earth governments, especially the Government of the United States, are in communication or cooperation with extraterrestrials despite public claims to the contrary, and further that some of these theories claim that the governments are explicitly allowing alien abduction.

Mystery airshipW
Mystery airship

Mystery airships or phantom airships are a class of unidentified flying objects best known from a series of newspaper reports originating in the western United States and spreading east during late 1896 and early 1897. According to researcher Jerome Clark, airship sightings were reported worldwide during the 1880s and 1890s. Mystery airship reports are seen as a cultural predecessor to modern claims of extraterrestrial-piloted flying saucer-style UFOs. Typical airship reports involved night time sightings of unidentified lights, but more detailed accounts reported ships comparable to a dirigible. Reports of the alleged crewmen and pilots usually described them as human-looking, although sometimes the crew claimed to be from Mars. It was popularly believed that the mystery airships were the product of some inventor or genius who was not ready to make knowledge of his creation public. For example, Thomas Edison was so widely speculated to be the mind behind the alleged airships that in 1897 he "was forced to issue a strongly worded statement" denying his responsibility.

UFO sightings in outer spaceW
UFO sightings in outer space

UFO sightings in outer space are sightings of unidentified flying objects reported by astronauts while in space that they could not explain at the time. These sightings have been claimed as evidence for alien visits by ufologists. Some of the alleged sightings never occurred: science fiction writer Otto Binder perpetuated a hoax claiming Apollo 11 Commander Neil Armstrong had encountered UFOs during the Apollo mission. UFO proponents see comments by astronauts or photos processed by NASA as one of the "strongest bodies of evidence" because they are considered to be of high trustworthiness; however, NASA Assistant Administrator for Legislative Affairs, Robert F. Allnut, concluded in a 1970 letter, "after fifteen years of manned space voyages including space stations and landing on the Moon, spacemen have brought back not a shred of evidence – verbal, photographic, or otherwise – for the existence of extraterrestrial spacecraft, or 'UFOs'."
