Green Fireballs
Green fireballs are a type of unidentified flying object (UFO) that has been reported since the early 1950s. Early sightings primarily occurred in the southwestern United States, particularly in New Mexico. Although some ufologists and ufology organizations consider green fireballs to be of artificial extraterrestrial origin, mainstream, non-pseudoscientific explanations have been provided, including natural bolides. Reports and responses Early observations of green fireballs date to late 1948 New Mexico, and include reports from two plane crews, one civilian and the other military, on the night of December 5, 1948. These crews described the observed fireballs as a bright "green ball of fire" and "like a huge green meteor".Ruppelt, Edward J.

Unidentified Flying Object
An unidentified flying object (UFO), more recently renamed by US officials as a UAP (unidentified aerial phenomenon), is any perceived aerial phenomenon that cannot be immediately identified or explained. On investigation, most UFOs are identified as known objects or atmospheric phenomena, while a small number remain unexplained. Scientists and skeptic organizations such as the Committee for Skeptical Inquiry have provided prosaic explanations for a large number of claimed UFOs being caused by natural phenomena, human technology, delusions, or hoaxes. Small but vocal groups of ufologists favour unconventional, pseudoscientific hypotheses, often claiming that UFOs are evidence of extraterrestrial intelligence. Beliefs surrounding UFOs have inspired parts of new religions. While unusual sightings have been reported in the sky throughout history, UFOs became culturally prominent after World War II, escalating during the Space Age. The 20th century saw studies and investigat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Teller
Edward Teller ( hu, Teller Ede; January 15, 1908 – September 9, 2003) was a Hungarian-American theoretical physicist who is known colloquially as "the father of the hydrogen bomb" (see the Teller–Ulam design), although he did not care for the title, considering it to be in poor taste. Throughout his life, Teller was known both for his scientific ability and for his difficult interpersonal relations and volatile personality. Born in Hungary in 1908, Teller emigrated to the United States in the 1930s, one of the many so-called "Martians", a group of prominent Hungarian scientist émigrés. He made numerous contributions to nuclear and molecular physics, spectroscopy (in particular the Jahn–Teller and Renner–Teller effects), and surface physics. His extension of Enrico Fermi's theory of beta decay, in the form of Gamow–Teller transitions, provided an important stepping stone in its application, while the Jahn–Teller effect and the Brunauer–Emmett–Teller (BET ...

The Report On Unidentified Flying Objects
''The Report on Unidentified Flying Objects'' is a 1956 book by then-retired Air Force UFO investigator Edward J. Ruppelt, detailing his experience running Project Bluebook. The book was noted for its suggestion that a few UFO sightings might be linked to spikes of atomic radiation. Contemporary media summarized four topics discussed in the book: * There is "no real proof" that flying saucers exist—no reliable photographs, no "hardware". * While the Air Force is officially dismissive of the spaceship theory, that conclusion is "far from unanimous". * Some staff within the Air Force had produced a UFO analysis, called the "Project Sign, Estimate of the Situation", concluding that some UFOs were interplanetary spaceships. That analysis was rejected by Robertson Panel, a panel of scientists meeting in January 1953. * Technological explanations were not considered: "No one at the meeting gave a second thought to the possibility that the UFOs might be super-secret US aircraft or a ...

UFO Conspiracy Theory
UFO conspiracy theories are a subset of conspiracy theories which argue that various governments and politicians globally, in particular the Government of the United States, are suppressing evidence that unidentified flying objects are controlled by a non-human intelligence or built using alien technology. Such conspiracy theories usually argue that Earth governments are in communication or cooperation with extraterrestrial visitors despite public disclaimers, and further that some of these theories claim that the governments are explicitly allowing alien abduction. Individuals who have suggested that UFO evidence is being suppressed include United States Senator Barry Goldwater, British Admiral Lord Hill-Norton (former NATO head and chief of the British Defence Staff), American Vice Admiral Roscoe H. Hillenkoetter (first CIA director), Israeli brigadier general Haim Eshed (former director of space programs for the Israel Ministry of Defense), astronauts Gordon Cooper and Edg ...

Fallout
Nuclear fallout is the residual radioactive material propelled into the upper atmosphere following a nuclear blast, so called because it "falls out" of the sky after the explosion and the shock wave has passed. It commonly refers to the radioactive dust and ash created when a nuclear weapon explodes. The amount and spread of fallout is a product of the size of the weapon and the altitude at which it is detonated. Fallout may get entrained with the products of a pyrocumulus cloud and fall as black rain (rain darkened by soot and other particulates, which fell within 30–40 minutes of the atomic bombings of Hiroshima and Nagasaki). This radioactive dust, usually consisting of fission products mixed with bystanding atoms that are neutron-activated by exposure, is a form of radioactive contamination. Types of fallout Fallout comes in two varieties. The first is a small amount of carcinogenic material with a long half-life. The second, depending on the height of detonation, is ...

Bolide
A bolide is normally taken to mean an exceptionally bright meteor, but the term is subject to more than one definition, according to context. It may refer to any large crater-forming body, or to one that explodes in the atmosphere. It can be a synonym for a fireball, sometimes specific to those with an apparent magnitude of −14 or brighter. Definitions The word ''bolide'' (; from Italian via Latin, ) may refer to somewhat different phenomena depending on the context in which the word appears, and readers may need to make inferences to determine which meaning is intended in a particular publication. One sense refers to an extremely bright meteor, especially one that explodes in the atmosphere. In astronomy, it refers to a fireball about as bright as the full moon, and it is generally considered a synonym for a fireball. In geology, a bolide is a very large impactor. One definition describes a bolide as a fireball reaching an apparent magnitude of −14 or brightermore th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alamogordo
Alamogordo () is the seat of Otero County, New Mexico, United States. A city in the Tularosa Basin of the Chihuahuan Desert, it is bordered on the east by the Sacramento Mountains and to the west by Holloman Air Force Base. The population was 31,358 as of the 2020 census. Alamogordo is known for its connection with the 1945 Trinity test, which was the first ever explosion of an atomic bomb. Humans have lived in the Alamogordo area for at least 11,000 years. The present settlement, established in 1898 to support the construction of the El Paso and Northeastern Railroad, is an early example of a planned community. The city was incorporated in 1912. Tourism became an important economic factor with the creation of White Sands National Monument in 1933, which is still one of the biggest attractions of the city today. During the 1950s–60s, Alamogordo was an unofficial center for research on pilot safety and the developing United States' space program. Alamogordo is a c ...

Edward J
Edward is an English given name. It is derived from the Anglo-Saxon name ''Ēadweard'', composed of the elements '' ēad'' "wealth, fortune; prosperous" and '' weard'' "guardian, protector”. History The name Edward was very popular in Anglo-Saxon England, but the rule of the Norman and Plantagenet dynasties had effectively ended its use amongst the upper classes. The popularity of the name was revived when Henry III named his firstborn son, the future Edward I, as part of his efforts to promote a cult around Edward the Confessor, for whom Henry had a deep admiration. Variant forms The name has been adopted in the Iberian peninsula since the 15th century, due to Edward, King of Portugal, whose mother was English. The Spanish/Portuguese forms of the name are Eduardo and Duarte. Other variant forms include French Édouard, Italian Edoardo and Odoardo, German, Dutch, Czech and Romanian Eduard and Scandinavian Edvard. Short forms include Ed, Eddy, Eddie, Ted, Teddy and Ned. ...
