Here is your weekly reminder of Psalm 19 — Saturn’s Rings and Titan.
At least I think it’s Titan. It’s one of Saturn’s moons, anyway. This image was taken by the Cassini spacecraft as it orbited Saturn. The spacecraft is named after the 17th century Italian astronomer, Giovanni Cassini, who studied Saturn extensively.
Here you can see the outer rings of Saturn, including the Cassini Division (the large division between the rings) and the Encke Gap (the smaller gap between the outermost rings). The rings are made of icy and rocky particles that range in size from a thousandth of a millimeter (about the size of smoke particles) up to a meter. It is not known for certain how the rings were formed. One hypothesis is that a moon of Saturn was either ripped apart by Saturn’s gravity or smashed by an asteroid, and the debris formed the rings; another is that the rings are made of leftover material from the formation of the solar system.
