ScienceDaily: Astronomers Find First Habitable Earth-like Planet
Already, they've found another planet that most probably habitable.
To think, in what...48 years since the first person landed on the moon, we've already explored out solar system, and moved on to others and maybe already found another planet likes our own.
With our technology, in another 50 years, we might have half on the population on another planet.
EDIT: We REALLY need to spend more money on Space Technology.
