Scientist: There are dozens of billions Planet Earth in the universe Similar Kingdom

WASHINGTON - The universe was blanketed with a suitable planets where living creatures so, the astronomers said as reported by Dailymail.

Scientists who studied the stars similar to the sun found that nearly one of every four stars have rocky planets like Earth.

Many of these planets exist in the zone "Goldilocks" or areas where the water is not too hot but not too cold,

Their findings suggest that there may be tens of billions of planets like Earth, it was only in our galaxy - and trillions of planets throughout the universe, which can be inhabited.

Scientists have spent five years researching the 166 stars within 80 light years - or 470 trillion miles from Earth.

The planet is very far away and too small to be seen directly with telescopes, so astronomers observing the stars when they pulled gravitational pull of planets.

In this way, during the past decade, at least 500 planets outside the solar system has been found.

New research reported in the journal "Science", found that there are many Earth-like planets.

Researcher Dr. Andrew Howard, said: `of about 100 stars like the sun, one or two have a size of planets like Jupiter, approximately six in size as Neptune, and about 12 have a super size of the earth, between three to ten times the mass of the earth.

"If the planet is sought is between one half and two times the mass of the earth, we predict there are around 23 for every 100 stars, 'added Dr. Howard, University of California Berkeley.

This technique can only detect planets orbiting nearby stars, so the actual number even more.

Another decade, a new method of detecting planets and telescopes are more qualified to be revealed more clearly Earth-like planets, said the scientists.

"These results will change the view of astronomers about how planets are formed '" says researcher Professor Geoffrey Marcy, who is one of the hunters leading the planets.

Last month, astronomers announced the discovery of the planet most like Earth - a rocky planet three times larger than Earth, orbiting a star 20 million light-years away.

The planet seems to have a layer of atmosphere, the force of gravity as on earth - and may have a flow of water on its surface.
