Juno Post-Arrival News Conference

Jupiter may be two months past opposition, but it’s still big, bright and high to the south before 9 pm from the centre of the British Isles. The Galilean moons, their shadows and the Great Red Spot are all on show — plus mutual phenomena of the moons.

NASA’s Juno spacecraft has found Jupiter’s cloud belts and zones extend down some 3,000 kilometres and contain about 1 percent of the planet’s mass. Below that, the world seems to rotate as a nearly rigid body.

Jupiter has passed opposition, but the solar system’s largest planet is still putting on a magnificent show in the southern sky at dusk. Backyard telescopes readily reveal its Great Red Spot storm feature and four main moons constantly playing tag. Here’s our full guide to Jovian events visible from the UK in June.
