Astronomers have found at least seven Earth-sized planets orbiting the same star 40 light-years away, according to a study published Wednesday in the journal Nature. The findings were also announced at a news conference at NASA Headquarters in Washington.
Aussie astronomers have found the closest potentially habitable planet that's four times the size of earth just outside our solar system.
U.S. space agency NASA said Wednesday its Kepler spacecraft has verified the existence of 715 more planets orbiting stars outside the solar system.
One in five Sun-like stars may have planets about the size of Earth and a surface temperature conducive to life, U.S. researchers said Monday.
