The North Stars

Polaris, for centuries a beacon for celestial navigators, has been known for some time to be part of a multiple star system. Until recently, the only evidence of a close companion star were the measured effects - a wobble - on the North Star. Recently, however, the venerable Hubble Space Telescope has imaged this giant star’s close companion, providing visual confirmation of the triple star system. See HubbleSite for more information and images of this fantastic achievement.
