    Most of the searches for planets that could support life are focused on looking at stars. For life to form and survive, at least water-based life, the planet needs to be at a particular location in proximity to its star so that the temperature is just right. New computer simulations suggest that life might actually survive on a "rogue planet" that has been ejected from its planetary system through gravitational interaction with other planets. With a blanket of ice and geothermal heating, life on such a wandering planet might exist.... For a while.
