This enhanced-colour mosaic shows Daphnis, one of the moons in Saturn's rings, kicking up three waves on the edge of a ring gap. The image is part of a set collected by NASA's now-defunct Cassini spacecraft. Together, the set reveals new details about Saturn's rings, astronomers announced on June 14 in the journal Science.

NASA astronaut Christina Koch compiled this stunning long-exposure picture of Earth against a backdrop of wheeling stars as the International Space Station orbited above Namibia toward the Red Sea in July.
In August, the European Southern Observatory captured this colourful view of the wispy cloud Sharpless 2-296, which forms the “wings” of a stellar nursery called the Seagull Nebula.
