NASA’s Juno spacecraft has provided close-up shots of Jupiter’s largest moon for the first time in two decades.

Juno zoomed past icy Ganymede on Monday, passing within 1,038 kilometres, but it took time for the first images to be received on Earth.

The last time a spacecraft came that close was in 2000 when NASA's Galileo spacecraft swept past our solar system's biggest moon.

NASA has released Juno's first two pictures, highlighting Ganymede's craters and long, narrow features possibly related to tectonic faults.
