A study based on 151 multi-planetary systems found by NASA's Kepler space telescope shows that most have a planet -- or two or three -- at the right distance for liquid surface water, a condition believed to be necessary for life.

Scientists combined data collected by the Kepler telescope with computer models replicating preferential structures of planetary systems to calculate the likelihood that planets would end up in life-friendly orbits -- those properly distanced from their parent stars for liquid surface water.

The results of the study, published in the Monthly Notices of the Royal Astronomical Society, indicate that billions of stars in the Milky Way have planets in so-called "habital zones" suitable for liquid water - and possibly life.
