A paper co-authored by University of Hawaiʻi<\/span> at Mānoa astronomer Andrew Howard<\/strong> and visiting graduate student Erik Petigura<\/strong> has won the Cozzarelli Prize from the National Academy of Sciences<\/a>. Their paper titled The prevalence of Earth-size planets orbiting Sun-like stars<\/a><\/em> was judged the top physical and mathematical sciences paper published in the Proceedings of the National Academy of Sciences in 2013.<\/p>\n

The Cozzarelli Prize recognizes six outstanding papers in the Proceedings of the National Academy of Sciences in the major scientific disciplines covered by that journal.<\/p>\n

Petigura, Howard and University of California, Berkeley professor Geoffrey Marcy statistically determined that twenty percent of sun-like stars in our galaxy have Earth-size planets with surface temperatures that could support liquid water. The findings, gleaned from data collected from NASA<\/abbr>’s Kepler spacecraft and the W. M. Keck Observatory<\/a>, satisfied Kepler’s primary mission: a determination of the fraction of stars in our galaxy with potentially habitable planets.<\/p>\n
