Saturn is just rising on mid-April evenings. In 1610, when Galileo first turned his crude telescope at the planet, he could make out the rings only as two smaller spheres surrounding Saturn's main disk. It wasn't until 1655 that Christiaan Huygens made out the rings as a disk shape surrounding the planet. Huygens went on to discover Titan, Saturn's largest moon; in his honor, the Huygens probe, the first object to land on Titan, carried his name.
