Experts: Life possible on planets

CAPE CANAVERAL, Fla. — For the first time, astronomers have discovered seven Earth-size planets orbiting a single nearby star — and these new worlds could hold life. This cluster of planets is less than 40 light-years away in the constellation Aquarius, according to NASA and the Belgian-led research team who announced the discovery Wednesday. The planets circle tightly around a dim dwarf star called Trappist-1, barely the size of Jupiter.
