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.

According to a study in The Astronomical Study via Newsweek, an estimated six billion planets in Milky Way have the same structure as the Earth. This means that there is 18% of Sun-like stars that could host human beings in the future.
These Earth-like planets have roughly the same size, abundance in liquid water, and the same Sun-like stars that are signs of its possible habitable structure, which was said to be unique with Earth.
At the University of British Columbia, Astronomers, which have extrapolated from data from NASA's now-dead Kepler space telescope, found these findings.
"Our Milky Way has as many as 400 billion stars, with seven percent of them being G-type. That means less than six billion stars may have Earth-like planets in our Galaxy," astronomer Jaymie Matthews, a co-author of the study from the University of British Columbia, Canada, said in a statement.
The Milky Way contains up to 400 billion stars in space. A minimal percentage from this estimated number has Sun-like stars.
Just to be clear, the agency did not discover anything that shows other planets may cater to human beings. It was just a discovery of the estimated number of Earth-like planets, located in the Milky Way. However, it serves a huge mark in history.
"Estimating how common different kinds of planets are around different stars can provide important constraints on planet formation and evolution theories, and help optimize future missions dedicated to finding exoplanets," Michelle Kunimoto, another co-author of the new study from the University of British Columbia, said in the statement.

36 life-forms could be hiding in the Milky Way
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.
