Alien Planets Like Earth [2014 Documentary] NEW
Habitable alien planets similar to Earth may not be that rare in the universe, a new study suggests.
About one in five sunlike stars observed by NASA's planet-hunting Kepler spacecraft has an Earth-size planet in the so-called habitable zone, where liquid water — and, potentially life — could exist, according to the new study. If these results apply elsewhere in the galaxy, the nearest such planet could be just 12 light-years away.
"Human beings have been looking at the stars for thousands of years," said study researcher Erik Petigura, a graduate student at the University of California, Berkeley (UC Berkeley). "How many of those stars have planets that are in some way like Earth?
astrophysicists and theoretical physicists argue among themselves whether we are not alone in this universe,i watched Niel de gras tyson once stating that there is a very high probability if there is life else where in the universe,but the most known scientist in the world,Stephen Hawkins states "if they were there,they could must have walked to our planet" also Hawkins is worried by the fact that when two civilizations once encounter one another,the superior one exploit another.
