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?
