This on-line news article introduces the Goldilocks Zone, an area of space adequate for the survival of life. Initially believed to be a remarkably small region of space that didn't even include the whole Earth, recent discoveries of extremophiles found thriving in unlikely habitats are convincing scientists to change their definition. Scientists Elena Pikuta and Richard Hoover are highlighted for their discovery of the new species Tindallia californiensis and Spirochaeta americana in the extreme environment of Mono Lake, California.
