Science fiction on television and List of science fiction television programs Don Hastings left and Al Hodge right from Captain Video and His Video Rangers Science fiction and television have always had a close relationship. It featured fantasy and horror as well as science fiction, with each episode being a complete story. The original series ran until and was revived in
This hypothesis relies on the vast size and consistent physical laws of the observable universe. According to this argument, made by scientists such as Carl Sagan and Stephen Hawking as well as well-regarded thinkers such as Winston Churchill  it would be improbable for life not to exist somewhere other than Earth.
Alternatively, life may have formed less frequently, then spread—by meteoroidsfor example—between habitable planets in a process called panspermia. Numerous discoveries in such zones since have generated numerical estimates of Earth-like planets —in terms of composition—of many billions.
One of the study authors, Sam Levin, notes "Like humans, we predict that they are made-up of a hierarchy of entities, which all cooperate to produce an alien.
At each level of the organism there will be mechanisms in place to eliminate conflict, maintain cooperation, and keep the organism functioning. We can even offer some examples of what these mechanisms will be.
It has been suggested that this capacity arises with the number of potential niches a planet contains, and that the complexity of life itself is reflected in the information density of planetary environments, which in turn can be computed from its niches.
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.
It is also conceivable that there are forms of life whose solvent is a liquid hydrocarbonsuch as methaneethane or propane. These six elements form the basic building blocks of virtually all life on Earth, whereas most of the remaining elements are found only in trace amounts.
The carbon atom has the unique ability to make four strong chemical bonds with other atoms, including other carbon atoms. These covalent bonds have a direction in space, so that carbon atoms can form the skeletons of complex 3-dimensional structures with definite architectures such as nucleic acids and proteins.
Carbon forms more compounds than all other elements combined. The great versatility of the carbon atom makes it the element most likely to provide the bases—even exotic ones—for the chemical composition of life on other planets. Planetary habitabilityHabitability of natural satellitesand Exobiology Some bodies in the Solar System have the potential for an environment in which extraterrestrial life can exist, particularly those with possible subsurface oceans.
Important insights on the limits of microbial life can be gleaned from studies of microbes on modern Earth, as well as their ubiquity and ancestral characteristics. If extraterrestrial life was found on another body in the Solar Systemit could have originated from Earth just as life on Earth could have been seeded from elsewhere exogenesis.
The Nobel prize winner Francis Crickalong with Leslie Orgel proposed that seeds of life may have been purposely spread by an advanced extraterrestrial civilization,  but considering an early " RNA world " Crick noted later that life may have originated on Earth.
However, between an altitude of 50 and 65 kilometers, the pressure and temperature are Earth-like, and it has been speculated that thermoacidophilic extremophile microorganisms might exist in the acidic upper layers of the Venusian atmosphere.
Life on Mars Life on Mars has been long speculated.

Liquid water is widely thought to have existed on Mars in the past, and now can occasionally be found as low-volume liquid brines in shallow Martian soil.
Scientists have indications that heated subsurface oceans of liquid water may exist deep under the crusts of the three outer Galilean moons —Europa,    Ganymede     and Callisto.
Life on Europa Internal structure of Europa. The blue is a subsurface ocean. Such subsurface oceans could possibly harbor life.
Whether you are a science fiction fan, a space enthusiast or one of the millions who have watched astronauts gamboling about the moon's surface, you may have wondered how much you would weigh on. Science fiction (often shortened to Sci-Fi or SF) is a genre of speculative fiction, typically dealing with imaginative concepts such as advanced science and technology, spaceflight, time travel, and extraterrestrial alphabetnyc.come fiction often explores the potential consequences of scientific and other innovations, and has been called a "literature of ideas". What is the most realistic science-fiction book or movie dealing with life on other planets? What are some good fictional or non-fictional philosophical novels about life, relationships, and human nature?
Enceladus Enceladusa moon of Saturn, has some of the conditions for life, including geothermal activity and water vapor, as well as possible under-ice oceans heated by tidal effects.
The temperature and density of the plumes indicate a warmer, watery source beneath the surface. Life on Titan Titanthe largest moon of Saturnis the only known moon in the Solar System with a significant atmosphere.
Data from the Cassini—Huygens mission refuted the hypothesis of a global hydrocarbon ocean, but later demonstrated the existence of liquid hydrocarbon lakes in the polar regions—the first stable bodies of surface liquid discovered outside Earth.
Fred Hoyle and Chandra Wickramasinghe have proposed that microbial life might exist on comets and asteroids.Invisible Planets: Contemporary Chinese Science Fiction in Translation - Kindle edition by Ken Liu.
