Bloop Noise
The Bloop is the name given to an ultra-low frequency and extremely powerful underwater sound detected by the U.S. National Oceanic and Atmospheric Administration (NOAA) in 1997. The source of the sound remains unknown.
Numbers stations (or number stations) are shortwave radio stations of uncertain origin. In the 1950s, Time magazine reported that the numbers stations first appeared shortly after the war (World War II) and were using a format that had been used to send weather data during that war.
Numbers stations generally broadcast artificially generated voices reading streams of numbers, words, letters (sometimes using a spelling alphabet), tunes or Morse code. They are in a wide variety of languages and the voices are usually female, although sometimes men's or children's voices are used.
Dyatlov Pass Incident
The Dyatlov Pass incident refers to an event that resulted in the deaths of nine ski hikers in the northern Ural mountains on the night of February 2, 1959. It happened on the east shoulder of the mountain Kholat Syakhl The mountain pass where the incident occurred has since been named Dyatlov Pass after the group's leader, Igor Dyatlov
The lack of eyewitnesses and subsequent investigations into the hikers' deaths have inspired much speculation. Investigators at the time determined that the hikers tore open their tent from within, departing barefoot in heavy snow. Though the corpses showed no signs of struggle, two victims had fractured skulls, two had broken ribs, and one was missing her tongue. According to sources, four of the victims' clothing contained substantial levels of radiation. There is no mention of this in contemporary documentation; it only appears in later documents. Soviet investigators determined only that "a compelling unknown force" had caused the deaths. Access to the area was barred for skiers and other adventurers for three years after the incident. The chronology of the incident remains unclear due to the lack of survivors.
The Lead Masks Case was the name given to the events which led to the death of two Brazilian electronic technicians: Manoel Pereira da Cruz and Miguel José Viana. Their bodies were discovered on August 20, 1966.
The Wow! signal was a strong narrowband radio signal detected by Dr. Jerry R. Ehman on August 15, 1977, while working on a SETI project at the Big Ear radio telescope of The Ohio State University. The signal bore expected hallmarks of potential non-terrestrial and non-solar system origin. It lasted for the full 72-second duration that Big Ear observed it, but has not been detected again. Much attention has been focused on it in the media when talking about SETI results.
Amazed at how closely the signal matched the expected signature of an interstellar signal in the antenna used, Ehman circled the signal on the computer printout and wrote the comment "Wow!" on its side. This comment became the name of the signal.
This video has some extracts of the radio transmission
The Valentich disappearance describes an event on 21 October 1978 when 20-year-old Frederick Valentich disappeared in unknown circumstances while piloting a Cessna 182L light aircraft over Bass Strait, Australia. His intention was to land at King Island, pick up three or four friends there, and return to Moorabbin Airport.
During the 127 Nautical mile (235 km) private flight, Valentich advised Melbourne air traffic control he was being accompanied by an aircraft about 1,000 feet above him. He described unusual actions and features of the aircraft, reported that his engine had begun running roughly, and finally reported that "That strange aircraft is hovering on top of me again. It is hovering and it's not an aircraft".
No trace of Valentich or his aircraft was ever found, and a Department of Transport investigation concluded that the reason for the disappearance could not be determined.
There were numerous belated reports of a UFO sighting in Australia the night of the disappearance. Ken Williams, a spokesman for the Department of Transport, told the Associated Press that "it's funny all these people ringing up with UFO reports well after Valentich's disappearance.
The Voynich manuscript is a handwritten book thought to have been written in the early 15th century and comprising about 240 vellum pages, most with illustrations. Although many possible authors have been proposed, the author, script, and language remain unknown. It has been described as "the world's most mysterious manuscript".
Generally presumed to be some kind of ciphertext, the Voynich manuscript has been studied by many professional and amateur cryptographers, including American and British codebreakers from both World War I and World War II. Yet it has defied all decipherment attempts, becoming a historical cryptology cause célèbre. The mystery surrounding it has excited the popular imagination, making the manuscript a subject of both fanciful theories and novels.
The Taman Shud Case, also known as the "Mystery of the Somerton Man", is an unsolved case revolving around an unidentified man found dead at 6:30a.m., December 1, 1948, on Somerton beach in Adelaide, Australia.
Considered "one of Australia's most profound mysteries", the case has been the subject of intense speculation over the years regarding the identity of the victim, the events leading up to his death and the cause of death.
While scrutiny of the case has been mainly centred in Australia, there has also been coverage of the case internationally.
Are supernatural shadow-like figures of both modern folklore and paranormal popular culture that believers describe as dark humanoid forms or evasive specters that are seen mostly in peripheral vision. They are commonly regarded as malicious or evil spirits
The Cash-Landrum Incident was a reported Unidentified Flying Object sighting from the United States in 1980, which the witnesses insist was responsible for damage to their health. It is one of very few UFO cases to result in criminal court proceedings.
It can be classified as a Close Encounter of the Second Kind, due to its reported physical effects on the witnesses and their automobile.
I've heard of all of these, and actually have a bunch of numbers stations recordings floating around on my computer. they are absolutely creepy to listen to at night.
