If you think that the Earth is a special planet for us humans, you're mistaken. Astronomers recently found that there are six billion Earth-like planets in the Milky Way. Most of them have similar G-type main-sequence stars like Sun and even a region of liquid water that can be considered one of the proofs that these are habitable types of planets.

A week before the University of British Columbia found this huge number of Earth-like planets, the University of Nottingham discovered that there are possible 36 types of life-forms or alien civilizations living in the Milky Way.
"I think it is extremely important and exciting because for the first time we really have an estimate for this number of active intelligent, communicating civilizations that we potentially could contact and find out there is other life in the universe - something that has been a question for thousands of years and is still not answered," said Christopher Conselice, a professor of astrophysics at the University of Nottingham and a co-author of the research.
