Saturn is the sun's sixth planet, known for its colorful concentric rings. Saturn, referred to by NASA as the jewel of the solar system, has been at the center of the Cassini space agency's mission for 13 years. On Friday, September 20, NASA shared a beautiful frontal image of Saturn taken by the Cassini probe. The picture shows the sun illuminating the rings of the planet with a narrow strip of sunlight creeping over the curvature of the planet from above.
The dark side of the planet is the night side of Saturn, which is invisible from Earth.  The Saturn image was shared on Friday as part of NASA's Astronomy Picture of the Day – a series of daily imagery showing the beauty of the cosmos.
The Space Agency credited the photo to NASA's Jet Propulsion Laboratory (JPL) of the California Institute of Technology (Caltech), the Space Science Institute, and the astronomer Mindaugas Macijauskas
saying, "Still radiant in the night sky of planet Earth good telescope views on Saturn and his beautiful rings often make him a star at star parties.

"But this breathtaking view of the rings and night side of Saturn is from telescopes that are closer to the sun than from the outside planet. You can only bring Saturn's day into view.
"In fact, this image of Saturn's narrow, sunlit crescent was captured by the Cassini spaceship with the shadow of the night thrown across its broad and complex ring system." Travel around Saturn on September 1
Three days before the death jump, the spacecraft made a series of 36 images that were embroidered in this portrait.

The sun is directly above Saturn, causing the planet to cast its shadow over its rings.
NASA comments: "Cassini, a planetary-Earth robot ship, has been calling Saturn's orbit for 13 years before being instructed to dive into the gas giant's atmosphere on September 15, 2017.
"This magnificent mosaic consists of single images of approx. ssini's wide-angle camera just two days before her big collapse.
"Saturn's night is not seen again until another spaceship calls from Earth." Saturn
