White Dwarfs Could Be Fertile Ground For Other EarthsWashington DC (SPX) Mar 31, 2011 Planet hunters have found hundreds of planets outside the solar system in the last decade, though it is unclear whether even one might be habitable. But it could be that the best place to look for planets that can support life is around dim, dying stars called white dwarfs. In a new paper published Tuesday (March 29) in The Astrophysical Journal Letters, Eric Agol, a University of Washington associate professor of astronomy, suggests that potentially habitable planets orbiting white dwarfs could b ... read more |
