SEVEN EARTH-SIZE PLANETS FOUND ORBITING NEARBY STAR, WHICH COULD HOLD LIFE!

posted by Mark Robertson - 

NASA and Belgian researchers announced Wednesday (February 22nd) that seven Earth-size planets had been found orbiting a nearby star, and that there could potentially be life on them. The planets orbit a dim dwarf star called Trappist-1 and are less than 40 light-years away -- which is 235 trillion miles. Three of the planets are in what's known as the habitable zone, meaning in an orbit where water and life might possibly exist, and the others are close to it. Until the discovery of this cluster of planets, we'd only found two or three Earth-size planets orbiting around a star.
