New ##ell describes atomic clock with unprecedented precision . Clock is made with atoms of the element hydrogen . You 'd never need this level of precision for getting to work on time , but the clock could be used for scientific exploration and technological advancements in areas such as navigation systems , said study co-author Andrew Ludlow , researcher at the National Institute of Standards and Technology in Boulder , Colorado . Clock is at the National Institute of Standards and Technology in Colorado . Efforts are under way to make the clock small enough to send into space .
