BBCnews is carrying this report summarizing new research that claims Earth-like planets may be far more common than we imagine. By using new computer models, scientists have discovered that the same environment that causes Jupiter-like planets to end up so close to their stars creates planet-making opportunities in the "habitable zones" of the system. The thinking goes that we may not be able to see them, but they certainly might be there, even in a system with something five times the size of Jupiter whirling around its star two or three times a day.
