Understanding planetary habitability is partly an extrapolation of the Earth 's conditions, as this is the only planet currently known to support life .
Planetary habitability - Wikipedia, the free encyclopedia
An artist's conception shows a terraformed Mars in four stages of development. Terraforming (literally, "Earth-shaping") of a planet , moon , or other body is the hypothetical process of deliberately modifying its atmosphere , temperature , surface topography or ecology to be similar to the biosphere of Earth , in order to make it habitable by humans .

Astrobiology is the study of the origin , evolution , distribution, and future of extraterrestrial life . 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. [ 2 ] (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.) [ 3 ]

Kardashev scale - Wikipedia, the free encyclopedia
The Kardashev scale is a method of measuring an advanced civilization's level of technological advancement.The multiverse (or meta-universe , metaverse ) is the hypothetical set of multiple possible universes (including the historical universe we consistently experience) that together comprise everything that exists and can exist: the entirety of space , time , matter , and energy as well as the physical laws and constants that describe them. The term was coined in 1895 by the American philosopher and psychologist William James . [ 1 ] The various universes within the multiverse are sometimes called parallel universes .

Drake equation - Wikipedia, the free encyclopedia
The Drake equation is an equation used to estimate the number of detectable extraterrestrial civilizations in the Milky Way galaxy .
We could spot alien civilizations from the light of their cities
There's no surefire way to find evidence of alien civilizations — indeed, they're basically all long shots — but a new method could reveal the existence of aliens just like us. And we've almost got the technology needed to do it. It's always dangerous to assume that another intelligent species would evolve along the same general lines as humans, but there are some reasonable assumptions that we can make.An international team of astronomers have reached the most definitive conclusion, one with profound implications: our galaxy contains a minimum of 100 billion planets . Of those, most are small planets like ours.
