Distant Planet May Have the Right Stuff

Planet Gliese 581g, the so-called Goldilocks planet whose discovery was announced earlier this week, may help prove Earth is not the only habitable planet in the universe. One reason for that is because it was so readily discovered — scientists found it after looking at only nine nearby stars. “Planets in the habitable zone seem to be amazingly common based on the fact that we found this one in such a short period of time,” Gillian Wilson, an associate professor in the department of physics and astronomy at the University of California Riverside, told TechNewsWorld.
