Scientists recently discovered a near-Earth planetoid orbiting a star only about 20 lightyears away. What does it MEAN?! Could it support human life outside of our solar system? Of course it?s got issues... it may be tidally locked, and we don?t actually know what it?s atmosphere is made of. Oh, and traveling 20 lightyears would take about 180,000 years using current propulsion methods. But a man can dream, right?!
