NASA’s Juno spacecraft continues to beam back spectacular pictures of Jupiter’s turbulent atmosphere, including this stunning view of a dark vortex spinning in a jet stream. It is surrounded by bright, higher-altitude clouds that have “puffed up into the sunlight,” according to a NASA description. The colour-enhanced image was captured 29 May when Juno was about 14,800 kilometres (9,200 miles) above Jupiter’s cloud tops at about 52 degrees north latitude. Citizen scientists Gerald Eichstädt and Seán Doran processed the image from Juno’s JunoCam instrument and named it Jupiter Abyss. Juno is now more than halfway through its extended mission to study the atmosphere and deep interior of the solar system’s largest planet.
Observer’s in the UK and Western Europe should look low to the southwest an hour after sunset on Friday, 30 June to glimpse the almost first quarter Moon a low-power binocular field of view to the right of Jupiter in bright twilight. The following night finds the waxing gibbous Moon forming a near isosceles triangle with the planet and first-magnitude star Spica in Virgo.
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.
