Will we find someday life without a home planet?
Revealing properties of other worlds in our Solar system, we gradually realize that the Earth is unique. Only at our planet’s surface was liquid water; only we had a complex, multicellular life, whose existence can be guessed, glancing from orbit; only we had copious amounts of atmospheric oxygen. In other worlds can be underground oceans or evidence of liquid water in the past, perhaps even single-celled organisms. Of course, in other solar systems might have Earth-like worlds, with similar conditions for the emergence of life. But that life existed, the presence of the world earth-like is not required. The latest findings of scientists show that the world may not even be needed. Perhaps life is in the depths of interstellar space.
