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
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 theoretical process of deliberately modifying its atmosphere, temperature, surface topography or ecology to be similar to the biosphere of Earth to make it habitable by Earth-like life.

Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe: extraterrestrial life and life on Earth. 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. (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.)

The Kardashev scale is a method of measuring a civilization's level of technological advancement, based on the amount of energy a civilization is able to utilize.

The multiverse (or meta-universe) is the hypothetical set of infinite or finite 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. The various universes within the multiverse are sometimes called parallel universes.
Drake Vs Fermi...
The Drake equation is a probabilistic argument used to estimate the number of active, communicative 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.

Exoplanet Atlas full of errors – VisualJournalism When you do graphics for print in Wired – and then post on your blog about the process – stressing how much attention you pay to the details, then you’re asking for it. Sorry, David McCandless … (Click the graphic for full-size at Wired and read the blogpost at information is beautiful here) Your Exoplanet Atlas is full of errors. According to your own description, you have three designers and three researchers working on the project for nine months doing 26 drafts, and yet it takes only a very simple check-up to realize, that this Atlas is not to be trusted.
1. Introduction ‘Astrobiology is the study of things that do not exist.’ This well-known statement can be dismissed as flippant cynicism, but one might suggest that in its vernacular way it is struggling to grasp what on earth (so to speak) we might expect to find. Consider the presumed alternatives: will the extra-terrestrials be utterly familiar, completely alien (whatever that is supposed to mean) or is the search a complete waste of time? Predicting what extra-terrestrials will be like: and preparing for the worst
Space Colonization Space colonization (also called space settlement, or extraterrestrial colonization) is permanent human habitation outside of Earth. There are several arguments for space colonization that can be made: survival of human civilization and the biosphere from possible disasters (natural or man-made), and the huge resources in space for expansion of human society, being the two most common ones. However, as of right now the building of a space colony would be a hugely difficult and massively expensive project.
