Nasa's Juno spacecraft has begun to send back pictures from its voyage to Jupiter, showing the giant planet half-obscured alongside three of its moons – Io, Europa and Ganymede.
It is the first glimpse of the giant gas planet taken by the spacecraft since it was successfully placed in orbit on 5 July, after nearly five years travelling through space, and reassured scientists Jupiter's extreme radiation had not damaged the probe at the end of its 1,740 million-mile journey.
"This scene from JunoCam indicates it survived its first pass through Jupiter's extreme radiation environment without any degradation and is ready to take on Jupiter," said principal scientist Scott Bolton. "We can't wait to see the first view of Jupiter's poles."

Bolton has previously described the task of ensuring Juno was captured by Jupiter's gravity to go into orbit as the "hardest thing Nasa has ever done".
Despite being taken 2.7 million miles away from the planet, the photos are detailed enough to capture some of Jupiter's atmospheric features, including the Great Red Spot. Higher resolution images will be transmitted on a closer flypast on 27 August.
Juno's initial capture orbit will last 53.5 days, with the spacecraft swooping between the planet and the belts of extreme radiation which surround it. At its closest point, the probe will be only 3,000 miles from Jupiter's cloud tops.
Jupiter's main gases, hydrogen and helium, are the same as those of the Sun, leading scientists to believe it was the first planet to form and that Juno's mission - to "investigate the planet's origins, interior structure, deep atmosphere and magnetosphere" – will reveal more about the origins of our solar system.
Nasa's Juno spacecraft arrives in Jupiter orbit
05 July
After a five-year journey through the solar system, Nasa's Juno spacecraft has successfully been placed in orbit around Jupiter.
Scientists in California waited anxiously as the spacecraft performed a 35-minute main-engine burn to slow itself down by 1,212mph to allow itself to be captured by Jupiter's gravity.
Cheers erupted after the spacecraft indicated the burn was complete and everything had gone as planned.
"Welcome to Jupiter," declared mission control.
The burn time was "within one second of the predicted time, putting it in exactly the orbit it needed", says The Guardian.
Juno chief scientist Scott Bolton described it as the "hardest thing Nasa has ever done".
"Engineers had warned in advance that the engine firing was fraught with danger," says the BBC. "No previous spacecraft has dared pass so close to Jupiter; its intense radiation belts can destroy unprotected electronics."
Juno will now orbit Jupiter 37 times over the next 20 months, travelling 2,600 miles above the planet, which is around 3,000 miles closer to the surface than any other mission.
