How do you look for something if you don't know what it looks like? The parachutes deploy perfectly, and gradually, swinging gently through the tenuous atmosphere, the little probe falls to the ground. Minutes later it jerks slightly as it unfurls its solar panels.

Jet Propulsion Lab -- A new NASA mission will scan the entire sky in infrared light in search of nearby cool stars, planetary construction zones and the brightest galaxies in the universe.     Called the Wide-field Infrared Survey Explorer, the mission has been approved to proceed into the preliminary design phase as the next in NASA's Medium-class Explorer program of lower cost, highly focused, rapid-development scientific spacecraft...

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.
