While visiting Australia, I had the opportunity on a particularly clear night to see the Southern Cross. Located in the Southern Hemisphere, this constellation is one of the most distinctive. Mariners and navigators began relying on it as early as the 15th century for direction and navigation through the seas. Although relatively small, it is visible throughout most of the year. The Southern Cross was so vivid on that dark night that even I could pick it out of the bundle of stars. It was truly a magnificent sight!
