We are not alone!  Today N.A.S.A announced that they have discovered a brand new solar system with Earth-sized planets orbiting a single star in the Trappist-1 system. Three of the seven planets are in the star’s habitable zone, meaning liquid water, and even more amazingly, life, could exist.  Don’t pack your bags yet…it would take 40 years to get there.
