Amateur astronomer Efrain Morales captured a breathtaking image of Titan's shadow sweeping across Saturn's cloud tops during a rare transit event on July 18 earlier this year.
Once every 15 years, Saturn's rings align edge-on with Earth, heralding the onset of a spectacular series of shadow transits as the large moon Titan passes between the gas giant's cloud surface and our parent star. Even at a distance of 846 million miles (1.36 billion kilometers), Titan's shadow is so vast that it can be seen from Earth with the correct telescopic equipment, making these transits must-see events for amateur astronomers.
