The goal is to help with the search for similar organisms in exoplanets, as the starlight reflected by planets rich in such organisms would have a specific spectrum, unlike that of starlight reflected from lifeless planets. If Earth was studied from afar with this system, it would reveal a shade of green, as a result of the abundance of plants with photosynthesis. In August 2011, NASA studied meteorites found on Antarctica, finding adenine , guanine , hypoxanthine and xanthine . Adenine and guanine are components of DNA, and

Following the 17th-century development of the novel as a literary form , Mary Shelley 's Frankenstein (1818) and The Last Man (1826) helped define the form of the science fiction novel. Brian Aldiss has argued that Frankenstein was the first work of science fiction. Edgar Allan Poe wrote several stories considered to be science fiction, including " The Unparalleled Adventure of One Hans Pfaall " (1835), which featured

Life on Earth started with an RNA world and later evolved to its current form, where some of the RNA tasks were transferred to DNA and proteins . Extraterrestrial life may still be stuck using RNA, or evolve into other configurations. It

Science fiction has communicated scientific ideas, imagined a range of possibilities, and influenced public interest in and perspectives on extraterrestrial life. One shared space is the debate over the wisdom of attempting communication with extraterrestrial intelligence. Some encourage aggressive methods to try to contact intelligent extraterrestrial life. Others – citing

Although some values may eventually be measured, others are based on social sciences and are not knowable by their very nature. This does not allow one to make noteworthy conclusions from the equation. Based on observations from the Hubble Space Telescope , there are nearly 2 trillion galaxies in the observable universe. It is estimated that at least ten per cent of all Sun-like stars have

If extraterrestrial life exists, it could range from simple microorganisms and multicellular organisms similar to animals or plants, to complex alien intelligences akin to humans . When scientists talk about extraterrestrial life, they consider all those types. Although it is possible that extraterrestrial life may have other configurations, scientists use
2502-570: A reasonable scientific explanation for any gathered data. In 1961, astronomer and astrophysicist Frank Drake devised the Drake equation as a way to stimulate scientific dialogue at a meeting on the search for extraterrestrial intelligence (SETI). The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilisations in the Milky Way galaxy . The Drake equation is: where: and Drake's proposed estimates are as follows, but numbers on
2641-443: A result has been conceived, even if hypothetical. Evolution requires life to be divided into individual organisms, and no alternative organisation has been satisfactorily proposed either. At the basic level, membranes define the limit of a cell, between it and its environment, while remaining partially open to exchange energy and resources with it. The evolution from simple cells to eukaryotes, and from them to multicellular lifeforms,

Life on Earth is quite ubiquitous across the planet and has adapted over time to almost all the available environments in it, extremophiles and the deep biosphere thrive at even the most hostile ones. As a result, it is inferred that life in other celestial bodies may be equally adaptive. However, the origin of life is unrelated to its ease of adaptation, and may have stricter requirements. A celestial body may not have any life on it, even if it

There is a tendency among science fiction enthusiasts as their own arbiter in deciding what exactly constitutes science fiction. David Seed says it may be more useful to talk about science fiction as the intersection of other more concrete subgenres. Damon Knight summed up the difficulty, saying "Science fiction

The Drake equation speculates about the existence of sapient life elsewhere in
4726-551: Is a difficulty for the study of extraterrestrial life. So far, humans have only set foot on the Moon and sent robotic probes to other planets and moons in the Solar System. Although probes can withstand conditions that may be lethal to humans, the distances cause time delays: the New Horizons took nine years after launch to reach Pluto . No probe has ever reached extrasolar planetary systems. The Voyager 2 has left

Another unknown aspect of potential extraterrestrial life would be the chemical elements that would compose it. Life on Earth is largely composed of carbon, but there could be other hypothetical types of biochemistry . A replacement for carbon would need to be able to create complex molecules, store information required for evolution, and be freely available in

The planetary context would also have an influence: a planet with higher gravity would have smaller animals, and other types of stars can lead to non-green photosynthesizers . The amount of energy available would also affect biodiversity , as an ecosystem sustained by black smokers or hydrothermal vents would have less energy available than those sustained by
10147-521: The Worlds (1898). His science fiction imagined alien invasion , biological engineering , invisibility , and time travel . In his non-fiction futurologist works he predicted the advent of airplanes , military tanks , nuclear weapons , satellite television , space travel , and something resembling the World Wide Web . Edgar Rice Burroughs 's A Princess of Mars , published in 1912,
10286-410: The area surrounding these hydrothermal vents which can suggest that some form of life can be supported even in the harshest of environments like the other planets in the solar system. The aspects of these harsh environments that make them ideal for the origin of life on Earth, as well as the possibility of creation of life on other planets, is the chemical reactions forming spontaneously. For example,
10425-568: The atom speeds, either too fast or too slow, make it difficult for specific ones to meet and start chemical reactions. A liquid medium also allows the transport of nutrients and substances required for metabolism. Sufficient quantities of carbon and other elements, along with water, might enable the formation of living organisms on terrestrial planets with a chemical make-up and temperature range similar to that of Earth. Life based on ammonia rather than water has been suggested as an alternative, though this solvent appears less suitable than water. It
10564-402: The cold temperatures would make such chemistry take place at a very slow pace. Water is rock-solid on the surface, but Titan does have a subsurface water ocean like several other moons. However, it is of such a great depth that it would be very difficult to access it for study. The science that searches and studies life in the universe, both on Earth and elsewhere, is called astrobiology . With
10703-413: The concept of powered armor exoskeletons . The German space opera series Perry Rhodan , written by various authors, started in 1961 with an account of the first Moon landing and has since expanded in space to multiple universes , and in time by billions of years. It has become the most popular science fiction book series of all time. In the 1960s and 1970s, New Wave science fiction
10842-506: The creation of microrobots and micromachinery , nanotechnology , smartdust , virtual reality , and artificial intelligence (including swarm intelligence ), as well as developing the ideas of "necroevolution" and the creation of artificial worlds. In 1965, Dune by Frank Herbert featured a much more complex and detailed imagined future society than had previously in most science fiction. In 1967 Anne McCaffrey began her Dragonriders of Pern science fantasy series. Two of
10981-521: The creation or maintenance of extraterrestrial life. However, there has been much historical evidence that some of the earliest and most basic forms of life on Earth originated in some extreme environments that seem unlikely to have harbored life at least at one point in Earth's history. Fossil evidence as well as many historical theories backed up by years of research and studies have marked environments like hydrothermal vents or acidic hot springs as some of
11120-563: The damage done to Earth's oceans with an advanced device called the Synchronium. She then dedicates her life to her father's cause, giving her a genuine sense of purpose that she had perhaps lacked earlier in the series. Kal grows jealous of the strong bond between Neri and Jason Bates, and begins hating Neri's friends on ORCA. As protest, Kal leaves the island. Neri and her ORCA mates go looking for him, but are unable to find him as he's been captured by UBRI. UBRI tricks Kal into believing that
11259-472: The devoted aficionado or fan—has a hard time trying to explain what science fiction is," and the lack of a "full satisfactory definition" is because "there are no easily delineated limits to science fiction." Another definition comes from The Literature Book by DK and is, "scenarios that are at the time of writing technologically impossible, extrapolating from present-day science...[,]...or that deal with some form of speculative science-based conceit, such as
11398-444: The difficulty for life to appear was not the temperature, but the scarcity of free heavy elements. Planetary systems emerged, and the first organic compounds may have formed in the protoplanetary disk of dust grains that would eventually create rocky planets like Earth. Although Earth was in a molten state after its birth and may have burned any organics that fell in it, it would have been more receptive once it cooled down. Once
11537-413: The end, the star blows much of its content back into the stellar medium, where it would join clouds that would eventually become new generations of stars and planets. Many of those materials are the raw components of life on Earth. As this process takes place in all the universe, said materials are ubiquitous in the cosmos and not a rarity from the Solar System. Earth is a planet in the Solar System ,
11676-439: The episodes, ran from 1959 to 1964. It featured fantasy , suspense , and horror as well as science fiction, with each episode being a complete story. Critics have ranked it as one of the best TV programs of any genre . The animated series The Jetsons , while intended as comedy and only running for one season (1962–1963), predicted many inventions now in common use: flat-screen televisions , newspapers on
11815-403: The first hominids appeared 60 million years ago. Life on other planets may have started, evolved, given birth to extraterrestrial intelligences, and perhaps even faced a planetary extinction event millions or even billions of years ago. The brief times of existence of Earth's species, when considered from a cosmic perspective, may suggest that extraterrestrial life may be equally fleeting under such
11954-415: The first places that life could have originated on Earth. These environments can be considered extreme when compared to the typical ecosystems that the majority of life on Earth now inhabit, as hydrothermal vents are scorching hot due to the magma escaping from the Earth's mantle and meeting the much colder oceanic water. Even in today's world, there can be a diverse population of bacteria found inhabiting
12093-762: The first science fiction novel . Some of the stories from The Arabian Nights , along with the 10th-century The Tale of the Bamboo Cutter and Ibn al-Nafis 's 13th-century Theologus Autodidactus , are also argued to contain elements of science fiction. Written during the Scientific Revolution and later the Age of Enlightenment are considered true science-fantasy books. Francis Bacon 's New Atlantis (1627), Johannes Kepler 's Somnium (1634), Athanasius Kircher 's Itinerarium extaticum (1656), Cyrano de Bergerac 's Comical History of
12232-410: The formation of planets, eventually arriving on young planets early in their formation. In December 2023, astronomers reported the first time discovery, in the plumes of Enceladus , moon of the planet Saturn , of hydrogen cyanide , a possible chemical essential for life as we know it, as well as other organic molecules , some of which are yet to be better identified and understood. According to
12371-486: The genre, it describes the history of humanity from the present onwards across two billion years. In 1937, John W. Campbell became editor of Astounding Science Fiction , an event that is sometimes considered the beginning of the Golden Age of Science Fiction , which was characterized by stories celebrating scientific achievement and progress . The "Golden Age" is often said to have ended in 1946, but sometimes
12510-455: The giant planets themselves are highly unlikely to have life, there is much hope to find it on moons orbiting these planets. Europa , from the Jovian system, has a subsurface ocean below a thick layer of ice. Ganymede and Callisto also have subsurface oceans, but life is less likely in them because water is sandwiched between layers of solid ice. Europa would have contact between the ocean and
12649-404: The habitable zones vary according to the type of star, and even the solar activity of each specific star influences the local habitability. The type of star also defines the time the habitable zone will exist, as its presence and limits will change along with the stars stellar evolution. The Big Bang took place 14 billion years ago, the Solar System was formed 4 and a half billion years ago, and
12788-571: The hierarchy of lifeforms from Earth for simplicity, as it is the only one known to exist. The first basic requirement for life is an environment with non-equilibrium thermodynamics , which means that the thermodynamic equilibrium must be broken by a source of energy. The traditional sources of energy in the cosmos are the stars, such as for life on Earth, which depends on the energy of the sun. However, there are other alternative energy sources, such as volcanoes , plate tectonics , and hydrothermal vents . There are ecosystems on Earth in deep areas of
12927-403: The hopes of facilitating cross-species communication. A significant portion of the series takes place on ORCA itself, and looks at the activities of its inhabitants, which includes the school-aged children of the resident scientists, such as Jason and Brett. Jason discovers Neri while on a whale-tracking expedition with his mother. While attempting to tag a whale using a harpoon from the boat, Jason
13066-477: The implications of the Internet and the expanding information universe, questions about biotechnology , nanotechnology , and post-scarcity societies . Recent trends and subgenres include steampunk , biopunk , and mundane science fiction . The first, or at least one of the first, recorded science fiction film is 1902's A Trip to the Moon , directed by French filmmaker Georges Méliès . It
13205-415: The late 1940s and the 1950s are included. In 1942, Isaac Asimov started his Foundation series , which chronicles the rise and fall of galactic empires and introduced psychohistory . The series was later awarded a one-time Hugo Award for "Best All-Time Series". Theodore Sturgeon 's More Than Human (1953) explored possible future human evolution . In 1957, Andromeda: A Space-Age Tale by
13344-440: The life-abundant Earth. However, there are many extreme and chemically harsh ecosystems on Earth that do support forms of life and are often hypothesized to be the origin of life on Earth. Hydrothermal vents , acidic hot springs, and volcanic lakes are examples of life forming under difficult circumstances, provide parallels to the extreme environments on other planets and support the possibility of extraterrestrial life. Since
13483-468: The male should lead (as he had been indoctrinated into the matriarchal social mores of his people), and he creates an alliance with Dr. Hellegren to steal the Synchronium pieces that Neri and Mera have hidden in a secret cave. When the rebellion in the Ocean World is growing, Mera escapes to Earth and is reunited with Neri. But PRAXIS sees this pyramid as a danger to the Earth. Much of the final series
13622-543: The medium. To create DNA , RNA , or a close analog, such an element should be able to bind its atoms with many others, creating complex and stable molecules. It should be able to create at least three covalent bonds: two for making long strings and at least a third to add new links and allow for diverse information. Only nine elements meet this requirement: boron , nitrogen , phosphorus , arsenic , antimony (three bonds), carbon , silicon , germanium and tin (four bonds). As for abundance, carbon, nitrogen, and silicon are
13761-478: The mid-20th century, active research has taken place to look for signs of extraterrestrial life, encompassing searches for current and historic extraterrestrial life, and a narrower search for extraterrestrial intelligent life . Depending on the category of search, methods range from analysis of telescope and specimen data to radios used to detect and transmit communications. The concept of extraterrestrial life, and particularly extraterrestrial intelligence, has had
13900-456: The modern genre primarily arose in the 19th and early 20th centuries when popular writers began looking to technological progress and speculation. Mary Shelley 's Frankenstein , written in 1818, is often credited as the first true science fiction novel . Jules Verne and H.G. Wells are pivotal figures in the genre's development. In the 20th century, expanded with the introduction of space operas , dystopian literature, pulp magazines , and
14039-572: The most abundant ones in the universe, far more than the others. On Earth's crust the most abundant of those elements is silicon, in the Hydrosphere it is carbon and in the atmosphere, it is carbon and nitrogen. Silicon, however, has disadvantages over carbon. The molecules formed with silicon atoms are less stable, and more vulnerable to acids, oxygen, and light. An ecosystem of silicon-based lifeforms would require very low temperatures, high atmospheric pressure , an atmosphere devoid of oxygen, and
14178-504: The native planet that may not be caused by natural causes. There are three main types of techno-signatures considered: interstellar communications , effects on the atmosphere, and planetary-sized structures such as Dyson spheres . Organizations such as the SETI Institute search the cosmos for potential forms of communication. They started with radio waves , and now search for laser pulses as well. The challenge for this search
14317-490: The natural ecology of the ocean around ORCA. Eventually, they put in play an effort to build the so-called "ORCA City", an elaborate underwater construction that will likely eradicate much of the natural life on the seabed . In response, Dr. Bates's mission changes over the course of the series from cetologist to environmental protectionist . This role becomes more prominent beginning with the third series, when UBRI representatives establish themselves on board ORCA. Accordingly,
14456-478: The novellas included in the first novel, Dragonflight , made McCaffrey the first woman to win a Hugo or Nebula Award . In 1968, Philip K. Dick 's Do Androids Dream of Electric Sheep? was published. It is the literary source of the Blade Runner movie franchise . In 1969, The Left Hand of Darkness by Ursula K. Le Guin was set on a planet in which the inhabitants have no fixed gender . It
14595-418: The ocean that do not receive sunlight, and take energy from black smokers instead. Magnetic fields and radioactivity have also been proposed as sources of energy, although they would be less efficient ones. Life on Earth requires water in a liquid state as a solvent in which biochemical reactions take place. It is highly unlikely that an abiogenesis process can start within a gaseous or solid medium:
14734-568: The origin of extraterrestrial life. The Solar System has a wide variety of planets, dwarf planets, and moons, and each one is studied for its potential to host life. Each one has its own specific conditions that may benefit or harm life. So far, the only lifeforms found are those from Earth. No extraterrestrial intelligence other than humans exists or has ever existed within the Solar System. Astrobiologist Mary Voytek points out that it would be unlikely to find large ecosystems, as they would have already been detected by now. The inner Solar System
14873-468: The others are used in other biological processes. The studies ruled out pollution of the meteorites on Earth, as those components would not be freely available the way they were found in the samples. This discovery suggests that several organic molecules that serve as building blocks of life may be generated within asteroids and comets. In October 2011, scientists reported that cosmic dust contains complex organic compounds ("amorphous organic solids with
15012-553: The planetary core ceased to generate a magnetic field, solar winds removed the atmosphere and the planet became vulnerable to solar radiation. Ancient life-forms may still have left fossilised remains, and microbes may still survive deep underground. As mentioned, the gas giants and ice giants are unlikely to contain life. The most distant solar system bodies, found in the Kuiper Belt and outwards, are locked in permanent deep-freeze, but cannot be ruled out completely. Although
15151-614: The play RUR , written by the Czech playwright Karel Čapek , broadcast live from the BBC's Alexandra Palace studios on 11 February 1938. The first popular science fiction program on American television was the children's adventure serial Captain Video and His Video Rangers , which ran from June 1949 to April 1955. The Twilight Zone (the original series), produced and narrated by Rod Serling , who also wrote or co-wrote most of
15290-511: The precise differences that lead to beneficial or harmful conditions for life. And despite the conditions against life on Venus , there are suspicions that microbial life-forms may still survive in high-altitude clouds. Mars is a cold and almost airless desert, inhospitable to life. However, recent studies revealed that water on Mars used to be quite abundant, forming rivers, lakes, and perhaps even oceans. Mars may have been habitable back then, and life on Mars may have been possible. But when
15429-456: The probability of the existence of extraterrestrial civilisations and the lack of evidence for such civilisations is known as the Fermi paradox . Dennis W. Sciama claimed that life's existence in the universe depends on various fundamental constants. Zhi-Wei Wang and Samuel L. Braunstein suggest that a random universe capable of supporting life is likely to be just barely able to do so, giving
15568-476: The probe to study ocean water. Still, Cassini detected complex organic molecules, salts, evidence of hydrothermal activity, hydrogen, and methane. Titan is the only celestial body in the Solar System besides Earth that has liquid bodies on the surface. It has rivers, lakes, and rain of hydrocarbons, methane, and ethane, and even a cycle similar to Earth's water cycle . This special context encourages speculations about lifeforms with different biochemistry, but
15707-438: The problems of survival of life on other planets. However, he also considered that the conditions found on Mars were incompatible with carbon based life. Even if extraterrestrial life is based on carbon and uses water as a solvent, like Earth life, it may still have a radically different biochemistry . Life is generally considered to be a product of natural selection . It has been proposed that to undergo natural selection
15846-468: The reaction of human beings to changes in science and technology ." Robert A. Heinlein wrote that "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 ." American science fiction author and editor Lester del Rey wrote, "Even
15985-433: The researchers, "these [newly discovered] compounds could potentially support extant microbial communities or drive complex organic synthesis leading to the origin of life ." Although most searches are focused on the biology of extraterrestrial life, an extraterrestrial intelligence capable enough to develop a civilization may be detectable by other means as well. Technology may generate technosignatures , effects on
16124-426: The right conditions on Earth were met, life started by a chemical process known as abiogenesis . Alternatively, life may have formed less frequently, then spread – by meteoroids , for example – between habitable planets in a process called panspermia . During most of its stellar evolution stars combine hydrogen nuclei to make helium nuclei by stellar fusion, and the comparatively lighter weight of helium allows
16263-405: The right side of the equation are agreed as speculative and open to substitution: 10,000 = 5 ⋅ 0.5 ⋅ 2 ⋅ 1 ⋅ 0.2 ⋅ 1 ⋅ 10,000 {\displaystyle 10{,}000=5\cdot 0.5\cdot 2\cdot 1\cdot 0.2\cdot 1\cdot 10{,}000} The Drake equation has proved controversial since, although it is written as
16402-422: The rocky surface, which helps the chemical reactions. It may be difficult to dig so deep in order to study those oceans, though. Enceladus , a tiny moon of Saturn with another subsurface ocean, may not need to be dug, as it releases water to space in eruption columns . The space probe Cassini flew inside one of these, but could not make a full study because NASA did not expect this phenomenon and did not equip
16541-532: The same samples suggests that a non-biological reaction is a more likely hypothesis. In February 2005 NASA scientists reported they may have found some evidence of extraterrestrial life on Mars. The two scientists, Carol Stoker and Larry Lemke of NASA's Ames Research Center , based their claim on methane signatures found in Mars's atmosphere resembling the methane production of some forms of primitive life on Earth, as well as on their own study of primitive life near
16680-648: The series gained popularity through syndication and extraordinary fan interest . It became a very popular and influential franchise with many films , television shows , novels , and other works and products. Star Trek: The Next Generation (1987–1994) led to six additional live action Star Trek shows: Deep Space Nine (1993–1999), Voyager (1995–2001) , Enterprise (2001–2005), Discovery (2017–2024), Picard (2020–2023), and Strange New Worlds (2022–present), with more in some form of development. Extraterrestrial life Extraterrestrial life , or alien life (colloquially, alien ),
16819-478: The series shifts to a more serious tone in its later series. As Neri gradually discovers more of her island and ORCA, she also begins to understand her greater purpose. This self-awakening is particularly enhanced by encounters with others of her kind. In the second series, she discovers her sister, Mera, and the two are given the opportunity to return to their home planet. Mera avails herself of this option, but Neri stays, feeling that she must discover what her father
16958-491: The show was repeated on the ABC in Australia, as part of their ABC Kids afternoon block of children's programs. The series began airing in 2011 on children's channel ABC3 . In Perth, the series screens on West TV on Sundays at 5:30pm, with encore screenings the following Saturday at 11:30am. Common Sense Media gave the show a rating of 4 out of 5 stars, saying "The plot is almost as complex and twisty [as Lost ]...the action
17097-399: The star to release the extra energy. The process continues until the star uses all of its available fuel, with the speed of consumption being related to the size of the star. During its last stages, stars start combining helium nuclei to form carbon nuclei. The higher-sized stars can further combine carbon nuclei to create oxygen and silicon, oxygen into neon and sulfur, and so on until iron. In
17236-482: The stellar evolution of stars and planets, it is usually not taken into account by astrobiology. There is an area around a star, the circumstellar habitable zone or "Goldilocks zone", where water may be at the right temperature to exist in liquid form at a planetary surface. This area is neither too close to the star, where water would become steam, nor too far away, where water would be frozen as ice. However, although useful as an approximation, planetary habitability
17375-508: The study of Earth's life, the only known form of life, astrobiology seeks to study how life starts and evolves and the requirements for its continuous existence. This helps to determine what to look for when searching for life in other celestial bodies. This is a complex area of study, and uses the combined perspectives of several scientific disciplines, such as astronomy , biology , chemistry , geology , oceanography , and atmospheric sciences . The scientific search for extraterrestrial life
17514-539: The survival and possible origin of life on Earth . With the little amount of information that scientists have found regarding the atmosphere on other planets in the Milky Way galaxy and beyond, the atmospheres are most likely reducing or with very low oxygen levels, especially when compared with Earth's atmosphere. If there were the necessary elements and ions on these planets, the same carbon fixing, reduced chemical compounds occurring around hydrothermal vents could also occur on these planets' surfaces and possibly result in
17653-636: The tendency of technologically advanced human societies to enslave or destroy less advanced societies – argue it may be dangerous to actively draw attention to Earth. Initially, after the Big Bang the universe was too hot to allow life. 15 million years later , it cooled to temperate levels, but the elements that make up living things did not exist yet. The only freely available elements at that point were hydrogen and helium . Carbon and oxygen (and later, water ) would not appear until 50 million years later, created through stellar fusion. At that point,
17792-515: The term speculative fiction to be used instead for those that are more "serious" or "thoughtful". Some scholars assert that science fiction had its beginnings in ancient times , when the line between myth and fact was blurred. Written in the 2nd century CE by the satirist Lucian , A True Story contains many themes and tropes characteristic of modern science fiction, including travel to other worlds, extraterrestrial lifeforms , interplanetary warfare, and artificial life . Some consider it
17931-403: The threat of UBRI fades, to be replaced by a new organization, PRAXIS (Preventative Response and eXtraterritorial Intelligence Service) and by rebels on the Ocean Planet. This group is dedicated to protecting against any threats posed by extraterrestrial life , and its agents come to believe Neri and her people are a problem for Earth. They thus chased Neri and the Bates boys around the world. When
18070-608: The universe. The science of extraterrestrial life is known as astrobiology . Speculation about the possibility of inhabited worlds beyond Earth dates back to antiquity. Early Christian writers discussed the idea of a "plurality of worlds" as proposed by earlier thinkers such as Democritus ; Augustine references Epicurus 's idea of innumerable worlds "throughout the boundless immensity of space" in The City of God . Pre-modern writers typically assumed extraterrestrial "worlds" are inhabited by living beings. William Vorilong , in
18209-445: The unusual properties of the meteorite were eventually explained as the result of inorganic processes, the controversy over its discovery laid the groundwork for the development of astrobiology. An experiment on the two Viking Mars landers reported gas emissions from heated Martian soil samples that some scientists argue are consistent with the presence of living microorganisms. Lack of corroborating evidence from other experiments on
18348-512: Was a humpback whale (a jali in Neri's native tongue) whom she names "Charlie" and with whom she can communicate. Later in the series, Neri's curiosity leads her to explore ORCA, while Dr. Bates' study of Charlie's whale song helps her identify Neri as the intended recipient of that song. Eventually, Dr Bates and her assistant, Dr. Winston Seth, become embroiled in Jason and Brett's effort to keep Neri
18487-442: Was aired in 1995, with a subsequent re-airing in 2002, although for unknown reasons this airing halted before Series 4 was complete. In 2004, the entire series was re-aired in full. In Vietnam, it was aired on VTV3 twice through from 1998 to 1999 and had a total 81 episodes (instead of 78). It is unknown why this was done, but presumably scenes from several episodes were edited out and made into extra installments. In recent years,
18626-417: Was habitable. It is unclear if life and intelligent life are ubiquitous in the cosmos or rare. The hypothesis of ubiquitous extraterrestrial life relies on three main ideas. The first one, the size of the universe allows for plenty of planets to have a similar habitability to Earth, and the age of the universe gives enough time for a long process analog to the history of Earth to happen there. The second
18765-404: Was influential on later filmmakers , bringing a different kind of creativity and fantasy . Méliès's innovative editing and special effects techniques were widely imitated and became important elements of the cinematic medium . 1927's Metropolis , directed by Fritz Lang , is the first feature-length science fiction film. Though not well received in its time, it is now considered
18904-484: Was known for its embrace of a high degree of experimentation, both in form and in content, and a highbrow and self-consciously " literary " or " artistic " sensibility . In 1961, Solaris by Stanisław Lem was published in Poland . The novel dealt with the theme of human limitations as its characters attempted to study a seemingly intelligent ocean on a newly discovered planet . Lem's work anticipated
19043-399: Was reported. Scientists search for biosignatures within the Solar System by studying planetary surfaces and examining meteorites . Some claim to have identified evidence that microbial life has existed on Mars. In 1996, a controversial report stated that structures resembling nanobacteria were discovered in a meteorite, ALH84001 , formed of rock ejected from Mars . Although all
19182-408: Was the first of his three- decade -long planetary romance series of Barsoom novels , which were set on Mars and featured John Carter as the hero . These novels were predecessors to YA novels , and drew inspiration from European science fiction and American Western novels . In 1924, We by Russian writer Yevgeny Zamyatin , one of the first dystopian novels, was published. It describes
19321-405: Was trying to do on Earth. In the third series, she gains entry into the downed spacecraft that originally brought her to Earth. There, she finds another of her people in suspended animation. The new character, Kal, proves to be the son of the commander of the vessel, and helps her tap into the ship's memory core. She finds the ship's log, in which Kal's mother explains that Neri's father was to repair
