Planet With 3 Suns

A NASA-funded astronomer has discovered a world where the 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 Mauna Kea mountain in Hawaii. The finding, reported in this week's issue of Nature, suggests that planets are more robust than previously believed. NO SALES REUTERS/NASA/Handout
