By comparing habituated zones on earth with those that don’t support life, researchers have determined that planetary habitation relies on the presence of liquid water, a narrow range of temperature and an energy source.

The increasing number of discovered planets and broadening of habitable terrestrial environments increase the probabilities of discovering extraterrestrial life.
