Can life emerge on planets around cooling stars?
Seattle WA (SPX) Dec 05, 2012
Astronomers find planets in strange places and wonder if they might support life. One such place would be in orbit around a white or brown dwarf. While neither is a star like the sun, both glow and so could be orbited by planets with the right ingredients for life. No terrestrial, or Earth-like planets have yet been confirmed orbiting white or brown dwarfs, but there is no reason to assume they don't exist. However, new research by Rory Barnes of the University of Washington and Rene Heller of Ger ... read more
