Alien planets similar to Earth may not be that hard to find in the universe after all.
According to a new study, the nearest planet to potentially support life could be just 12 light-years away.
A team of planet hunters estimated that about 22% of the sun-like stars in our galaxy may have planets about the size of earth, and sit in similar amounts of sunlight.
This discovery was made by NASA's Kepler Space Telescope, which was launched in 2009 to look for Earth-like planets around other stars.
Officials at NASA now say they are thrilled to finally begin to answer the question of how many stars have planets that are in some way like Earth.
"The potential is there and it's very exciting, because in the Kevlar's of planets that we now have, this is the first time we've had an Earth-like planet in the habitable zone of a sun-like star." said Neil DeGrasse Tyson
NASA officials also said that even if the planets have all the basic ingredients for life, scientists still don't know if life would ever get started that deep into space.
