Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2026 June 16 [2]Saturn is shown up close with its ring plane running up diagonally from the lower right. Two small moons are visible. Near the top of the planet are large dark bands that are shadows of the rings onto Saturn's cloud tops. Please see the explanation for more detailed information. Moons, Rings, Shadows, Clouds: Saturn (Cassini) Image Credit: [3]NASA, [4]JPL-Caltech, [5]Space Science Institute Explanation: While cruising around Saturn, be on the lookout for picturesque arrangements of moons, rings, and shadows. [6]One such striking sight occurred in 2005 and was captured by the then [7]Saturn-orbiting Cassini spacecraft. In the featured image, moons [8]Mimas (left) and [9]Tethys (right) are visible on either side of [10]Saturn's thin rings, which are seen nearly edge-on. Across the top of [11]Saturn are dark [12]shadows of the wide rings, exhibiting their impressive complexity. The [13]violet-light image brings up the texture of the backdrop: [14]Saturn's clouds. Cassini orbited Saturn [15]from 2004 until mid-2017, when the [16]robotic spacecraft was directed to [17]dive into Saturn to keep it from [18]contaminating any moons.
