SUMMARY: The chances of finding life somewhere else in the Universe depends on how many planets are capable of supporting life.

The team created mathematical models of known exoplanetary systems, and then added Earth-sized planets into the mix. They found that in half of all planetary systems they simulated, the gravity of the gas giants won't catastrophically affect the orbits of these smaller planets, giving life a chance to evolve.
