The 130 extrasolar planets discovered so far are in solar systems very different from our own, in which life-bearing planets like Earth are unlikely to exist. But an obscure characteristic of these planets and their stars has led astronomers to predict that our galaxy is brimming with solar systems like ours. The key to their prediction is something called metallicity.
