Juno Post-Arrival News Conference

As darkness falls, observers in Western Europe and the British Isles fortunate to have clear skies can view a naked-eye conjunction between largest planet Jupiter and the Moon. For telescope owners, Jupiter’s Great Red Spot will be on show, while Galilean moons Io and Europa partake in a close orbital dance.

Juno’s visible camera had a bird’s-eye view of Jupiter’s four largest moons over the last few weeks, recording the satellites in their orbital ballet around the giant planet as the spacecraft approached from above Jupiter’s north pole.

Chariklo is the largest confirmed centaur, a minor planet orbiting the Sun between Saturn and Uranus. In 2014, two rings were discovered around Chariklo. Soon after, scientists discovered that rings likely exist around another centaur, Chiron, but the origin of these rings remained a mystery — until now.
