NASA recently released this Cassini spacecraft image of Saturn’s moon Iapetus. The image, actually taken last August, shows Iapetus looking strikingly similar to the Chinese taiji symbol, what many called the yin-yang symbol. This symbol represents nature’s duality: up and down, black and white, hot and cold.
