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. (Nasa/Reuters)
