A detailed analysis of data collected by NASA’s Kepler space telescope has revealed an additional 219 possibleorbiting distant suns, including 10 roughly Earth-size worlds in the habitable zones of their host stars, researchers said Monday.
The analysis pushes Kepler’s tally to 4,034 planet candidates overall, of which 2,335 have been confirmed through additional observation and analysis. More than 30 of 49 terrestrial candidates have been confirmed orbiting in habitable zones where water can exist as a liquid and life as it’s known on Earth could, in theory, exist.
The new Kepler analysis also indicates extra-solar planets form in three general sizes, not two as previously thought. At one extreme are huge-class gas giants. In the middle are roughly Neptune-size…
