Celestial triple play

"A NASA-funded astronomer has discovered a world where one sun sets over the horizon, followed by a second sun and then a third, as pictured in this artist's conception released by NASA July 13, 2005.

"The new planet, called HD 188753 Ab, is the first known to reside in a classic triple-star system. The astronomer, Dr. Maciej Konacki of the California Institute of Technology, Pasadena, California, found the planet using the Keck I telescope atop Ma'una Kea in Hawai'i."
