Introduction

Life in other Planets or better said, extraterrestrial life is defined as life that does not originate from Earth. It is often also referred to as alien life, or simply aliens (or space aliens, to differentiate from other definitions of alien or aliens). These hypothetical forms of life range from simple bacteria-like organisms to beings far more complex than humans. The possibility that viruses might also exist extra terrestrially has been proposed.

UFO
An unidentified flying object, or UFO, in its most general definition, is any apparent anomaly in the sky (or near or on the ground, but observed hovering, landing, or departing into the sky) that is not readily identifiable as any known object or phenomenon by visual observation and/or use of associated instrumentation such as radar. These anomalies were referred to popularly as “flying saucers” or “flying discs” during the late 1940s and early 1950s.

Body

Alien life, such as bacteria, has been hypothesized to exist in the Solar System and throughout the universe. 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, it would be improbable for life not to exist somewhere other than Earth. This argument is embodied in the Copernican principle, which states that the Earth does not occupy a unique position in the Universe, and the mediocrity principle, which holds that there is nothing special about life on Earth. Life may have emerged independently at many places throughout the Universe. Alternatively life may form less frequently, then spread between habitable planets through panspermia or exogenesis In any case, complex organic molecules necessary for life may have formed in the protoplanetary disk of dust grains surrounding the Sun before the formation of the Earth based on computer model studies. According to these studies, this same process may also occur around other stars that acquire planets. (Also see Extraterrestrial organic molecules.) Suggested locations at which life might have developed include the planets Venu] and Mars, Jupiter’s moon Europa, and Saturn’s moons Titan and Enceladus. In May 2011, NASA scientists reported that Enceladus “is emerging as the most habitable spot beyond Earth in the Solar System for life as we know it”. Since the 1950s, scientists have promoted the idea that “habitable zones” as the most likely places for life to be found. Numerous discoveries in this zone since 2007 have stimulated estimations of frequencies of Earth-like habitats numbering in the many billions though as of 2013, only a small number of planets have been discovered in these zones. More recently, astrobiologists have increasingly shifted toward a “follow the energy” view of potential habitats.

UFO

CThe term “UFO” was officially created in 1953 by the United States Air Force (USAF) to replace the more popular terms because of the variety of shapes described other than “discs” or “saucers.” It was stated that a “UFOB” was “any airborne object which by performance, aerodynamic characteristics, or unusual features, does not conform to any presently known aircraft or
missile type, or which cannot be positively identified as a familiar object.” As originally defined, the term was restricted to those fractions of cases which remained unidentified after investigation, with USAF interest being for potential national security reasons and/or “technical aspects. The term UFO became more widespread during the 1950s, at first in professional literature, but later in popular use. UFOs garnered considerable interest during the Cold War, an era associated with a heightened concern for national security. Various studies, both governmental and civilian, have reached varying conclusions, some saying that the phenomenon does not represent a threat to national security nor does it contain anything worthy of scientific pursuit (e.g., 1953 CIA Robertson Panel, USAF Project Blue Book, Condon Committee), while others have reached the opposite conclusions (see, e.g., 1999 French COMETA study, 1948 USAF Estimate of the Situation, Sturrock panel). A number of military personnel and others have given statements about having witnessed UFOs themselves or having been privy to information about them. Culturally, the phenomenon has often been associated with extraterrestrial life or government-related conspiracy theories, and has become a popular theme in fiction, conclusion

Conclusion

My conclusion to this report is that there is a big possibility of life beyond our planet or even in ours, just that we don’t realize it still. It is hard to believe we are definitely alone in the universe and that in our sister’s galaxies could have life. But, still if I don’t look at it with my own eyes, I won’t completely believe.
