The Hubble Space Telescope’s Wide Field Camera 3 captured this razor-sharp image of Saturn on 20 June as the ringed planet made its closest approach to Earth in 2019 at a distance of 1.36 billion kilometres (845 million miles). The image reveals numerous ringlets and the faint inner regions of the vast ring system and the hexagon-shaped structure at the planet’s north pole. A huge storm in the north polar region that was seen last year has disappeared. This image is the second in an annual series of photos taken as part of the Outer Planets Atmospheres Legacy – OPAL – project.
