Astrobiology. Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe: extraterrestrial life and life on Earth.
This interdisciplinary field encompasses the search for habitable environments in our Solar System and habitable planets outside our Solar System, the search for evidence of prebiotic chemistry, laboratory and field research into the origins and early evolution of life on Earth, and studies of the potential for life to adapt to challenges on Earth and in outer space. Astrobiology addresses the question of whether life exists beyond Earth, and how humans can detect it if it does. (The term exobiology is similar but more specific — it covers the search for life beyond Earth, and the effects of extraterrestrial environments on living things.) Overview It is not known whether life elsewhere in the universe would utilize cell structures like those found on Earth.
(Chloroplasts within plant cells shown here.) Methodology Paranormal. This article is about unexplained phenomena.
For phenomena not subject to laws of nature, see supernatural. For unexplained but presumed natural phenomena, see preternatural. Paranormal events are events that can not readily be explained by "the range of normal experience or scientific explanation. " A paranormal phenomenon is different from hypothetical concepts such as dark matter and dark energy. Life. Life is a characteristic distinguishing physical entities having signaling and self-sustaining processes from those that do not, either because such functions have ceased (death), or because they lack such functions and are classified as inanimate. Biology is a science concerned with the study of life.
Though life is confirmed only on the Earth, many think that extraterrestrial life is not only plausible, but probable or inevitable. Other planets and moons in the Solar System have been examined for evidence of having once supported simple life, and projects such as SETI have attempted to detect radio transmissions from possible alien civilizations. According to the panspermia hypothesis, microscopic life exists throughout the Universe, and is distributed by meteoroids, asteroids and planetoids. Early theories. Red rain in Kerala. For other uses, see Red rain.
Rain water sample (left) and after the particles settled (right). Dried sediment (centre). The Kerala red rain phenomenon was a blood rain (red rain) event that occurred from 25 July to 23 September 2001, when heavy downpours of red-coloured rain fell sporadically on the southern Indian state of Kerala, staining clothes pink. Yellow, green, and black rain was also reported. Coloured rain was also reported in Kerala in 1896 and several times since, most recently in June 2012. Following a light microscopy examination, it was initially thought that the rains were coloured by fallout from a hypothetical meteor burst, but a study commissioned by the Government of India concluded that the rains had been coloured by airborne spores from locally prolific terrestrial algae. Occurrence
Alien visitation. Throughout history, some people have claimed experiences that are the supposed results of Alien Visitation.
While some of the factors of extraterrestrial visits range in variety, the basic structure stays the same, motivating further research into the topic. Overview Alien Visitation refers to an intentional encounter between an extraterrestrial being to a human. For Alien Visitation to be considered a real issue among researchers, extraterrestrials must be proven to have a valid motivation for visiting, and the encounter must be scientifically possible and probable. Progeny (film) Progeny is an American science fiction film released in 1999.
It was directed by Brian Yuzna and written by Aubrey Solomon and Stuart Gordon. The film stars Arnold Vosloo as Dr. Craig Burton, Jillian McWhirter as Sherry Burton, Brad Dourif as Dr. Bert Clavell and Lindsay Crouse as Dr. Alien (creature in Alien franchise) Necronom IV, Giger's surrealist print that formed the basis for the Alien's design The title of the film was decided late in the script's development.
O'Bannon had quickly dropped the film's original title, Star Beast, but could not think of a name to replace it. "I was running through titles, and they all stank", O'Bannon said in an interview, "when suddenly, that word alien just came out of the typewriter at me. Alien. Pascagoula Abduction. The Pascagoula Abduction occurred in 1973 when co-workers Charles Hickson and Calvin Parker claimed that they were abducted by aliens while fishing near Pascagoula, Mississippi.

Unsolved Mysteries of the Past (German: Erinnerungen an die Zukunft: Ungelöste Rätsel der Vergangenheit) is a book authored in 1968 by Erich von Däniken. It involves the hypothesis that the technologies and religions of many ancient civilizations were given to them by ancient astronauts who were welcomed as gods. Drake equation. The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy.
The equation was written in 1961 by Frank Drake not for purposes of quantifying the number of civilizations, but intended as a way to stimulate scientific dialogue at the world's first SETI meeting, in Green Bank, West Virginia. The equation summarizes the main concepts which scientists must contemplate when considering the question of other radio-communicative life. The Drake equation has proved controversial since several of its factors are currently unknown, and estimates of their values span a very wide range. This has led critics to label the equation a guesstimate, or even meaningless. History In September 1959, physicists Giuseppe Cocconi and Philip Morrison published an article in the journal Nature with the provocative title "Searching for Interstellar Communications.
Solway Firth Spaceman. Jim Templeton's photograph. The Solway Firth Spaceman (also known as the Solway Spaceman and the Cumberland Spaceman) refers to a figure seen in a photograph taken in 1964 by firefighter, photographer and local historian Jim Templeton (13 February 1920 - 27 November 2011). Wow! signal. Background The Wow! Signal was detected by Jerry R. Ehman on August 15, 1977, who was working on a SETI project at the now-defunct Big Ear radio telescope of The Ohio State University. The telescope was then located at Ohio Wesleyan University's Perkins Observatory in Delaware, Ohio, when Ehman spotted a surprising vertical column with the alphanumerical sequence “6EQUJ5,” which had occurred at 10:16 p.m. Exotheology. Not to be confused are UFO religions or ancient astronaut theories that posit that historical religious scripture or mythology was inspired by visits from extraterrestrials.
Alien Origin. Alien Origin is an 2012 American science fiction/Horror film produced by The Asylum and directed by Mark Atkins. The film stars Chelsea Vincent, Peter Pedrero, Philip Coc, Trey McCurley and Daniela Flynn. Science fiction. §Definition A futuristic setting is a common but not a necessary hallmark of science fiction. A common thread in science fiction is exploring the potential consequences of scientific and other innovations on people's lives. According to science fiction writer Robert A. Heinlein, "a handy short definition of almost all science fiction might read: realistic speculation about possible future events, based solidly on adequate knowledge of the real world, past and present, and on a thorough understanding of the nature and significance of the scientific method.
Science fiction is largely based on writing rationally about alternative possible worlds or futures. It is similar to, but differs from fantasy in that, within the context of the story, its imaginary elements are largely possible within scientifically established or scientifically postulated physical laws (though some elements in a story might still be pure imaginative speculation). §History Fermi paradox. Ancient astronauts in popular culture. Antônio Vilas Boas. Antônio Vilas-Boas (in many English sources misspelled "Villas-Boas") (1934–1991) was a Brazilian farmer who claimed to have been abducted by extraterrestrials in 1957.
Though similar stories had circulated for years beforehand, Vilas Boas' claims were among the first alien abduction stories to receive wide attention. Vilas-Boas' story Flying saucer. An alleged flying saucer seen over Passaic, New Jersey in 1952. List of reptilian humanoids. Reptilian humanoids comprise a common motif in mythology, folklore, science fiction, fantasy, conspiracy theories, ufology, and cryptozoology. Space Brothers. List of alleged extraterrestrial beings. This is a list of alleged extraterrestrial beings that have been reported in close encounters, claimed or speculated to be associated with UFOs. UFOs are "Unidentified Flying Objects" which are popularly believed to remain unidentified in terms of existing technology or natural phenomena even after rigorous attempts at identification.
