Sunset on HD 188753 Ab. This artist's animation shows the view from a hypothetical moon in orbit around the first known planet to reside in a tight-knit triple-star system. The gas giant planet, discovered using the Keck I telescope atop Mauna Kea in Hawaii, zips around a single star that is orbited by a nearby pair of pirouetting stars.
