Saturn

1. Saturn Mosaic

A total of 126 images taken over the course of two hours make up this mosaic picture of Saturn. The Cassini-Huygens spacecraft snapped the photos on October 6, 2004, when it was approximately 3.9 million miles (6.3 million kilometers) from Saturn. Cassini was on a four-year mission to explore the ringed planet.

2. Titan Halo

A halo surrounds Titan, Saturn’s largest moon. Titan’s atmosphere, almost entirely nitrogen, extends some 370 miles (600 kilometers) into space—ten times as far as Earth’s atmosphere.

3. Saturn and Moons

Two of Saturn’s 48 known moons are barely visible in this picture of the ringed planet. Mimas, at the upper right, has an enormous impact crater on one side, and Tethys, at the bottom, has a huge rift zone called Ithaca Chasma that runs nearly three-quarters of the way around the moon.

4. Saturn’s Rings

Saturn’s otherworldly rings encircle the planet and extend out for hundreds of thousands of kilometers. The rings—there are thousands—are made up of billions of ice and rock particles, thought to be pieces of comets, asteroids, or shattered moons.
