** Extraterrestrial life **

From Wikipedia, the free encyclopedia
Jump to: navigation, search
For other uses, see Astrobiology.
The official U.S. government position on extraterrestrial life, and the
three major efforts in the search for it:
#Looking for extrasolar planets (File: /Kepler/ spacecraft)
#Listening for signals (File: Allen array)
#Discovery and exploration of of the Solar System using robotic spacecraft
(File: /Curiosity/ rover)

*Extraterrestrial life* (from the Latin words: /extra/ ["beyond", or "not
of"] and /terrestris/ ["of or belonging to Earth"]) 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 development and testing of hypotheses on extraterrestrial life is known
as exobiology or astrobiology; the term astrobiology, however, includes the
study of life on Earth viewed in its astronomical context. Nonetheless,
scientists at the National Institutes of Health reported studies that life
in the universe may have begun "9.7±2.5 billion years ago", billions of
years before the Earth was formed, based on extrapolating the "genetic
complexity of organisms" [from "major phylogenetic lineages"] to earlier
times.^[1]^[2] Many scientists consider extraterrestrial life to be
plausible, but there is no direct evidence of its existence. Since the
mid-20th century, there has been an ongoing search for signs of
extraterrestrial life, from radios used to detect possible extraterrestrial
signals, to telescopes used to search for potentially habitable extrasolar
planets. It has also played a major role in works of science fiction.
